Frequently asked questions

What is the purpose of a literature review.

There are several reasons to conduct a literature review at the beginning of a research project:

  • To familiarize yourself with the current state of knowledge on your topic
  • To ensure that you’re not just repeating what others have already done
  • To identify gaps in knowledge and unresolved problems that your research can address
  • To develop your theoretical framework and methodology
  • To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

Frequently asked questions: Academic writing

A rhetorical tautology is the repetition of an idea of concept using different words.

Rhetorical tautologies occur when additional words are used to convey a meaning that has already been expressed or implied. For example, the phrase “armed gunman” is a tautology because a “gunman” is by definition “armed.”

A logical tautology is a statement that is always true because it includes all logical possibilities.

Logical tautologies often take the form of “either/or” statements (e.g., “It will rain, or it will not rain”) or employ circular reasoning (e.g., “she is untrustworthy because she can’t be trusted”).

You may have seen both “appendices” or “appendixes” as pluralizations of “ appendix .” Either spelling can be used, but “appendices” is more common (including in APA Style ). Consistency is key here: make sure you use the same spelling throughout your paper.

The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.

In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.

A lab report is usually shorter than a research paper.

The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:

  • Title: expresses the topic of your study
  • Abstract: summarizes your research aims, methods, results, and conclusions
  • Introduction: establishes the context needed to understand the topic
  • Method: describes the materials and procedures used in the experiment
  • Results: reports all descriptive and inferential statistical analyses
  • Discussion: interprets and evaluates results and identifies limitations
  • Conclusion: sums up the main findings of your experiment
  • References: list of all sources cited using a specific style (e.g. APA)
  • Appendices: contains lengthy materials, procedures, tables or figures

A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .

If you’ve gone over the word limit set for your assignment, shorten your sentences and cut repetition and redundancy during the editing process. If you use a lot of long quotes , consider shortening them to just the essentials.

If you need to remove a lot of words, you may have to cut certain passages. Remember that everything in the text should be there to support your argument; look for any information that’s not essential to your point and remove it.

To make this process easier and faster, you can use a paraphrasing tool . With this tool, you can rewrite your text to make it simpler and shorter. If that’s not enough, you can copy-paste your paraphrased text into the summarizer . This tool will distill your text to its core message.

Revising, proofreading, and editing are different stages of the writing process .

  • Revising is making structural and logical changes to your text—reformulating arguments and reordering information.
  • Editing refers to making more local changes to things like sentence structure and phrasing to make sure your meaning is conveyed clearly and concisely.
  • Proofreading involves looking at the text closely, line by line, to spot any typos and issues with consistency and correct them.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

Avoid citing sources in your abstract . There are two reasons for this:

  • The abstract should focus on your original research, not on the work of others.
  • The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

  • To help potential readers determine the relevance of your paper for their own research.
  • To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .

Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.

Whether you’re publishing a blog, submitting a research paper , or even just writing an important email, there are a few techniques you can use to make sure it’s error-free:

  • Take a break : Set your work aside for at least a few hours so that you can look at it with fresh eyes.
  • Proofread a printout : Staring at a screen for too long can cause fatigue – sit down with a pen and paper to check the final version.
  • Use digital shortcuts : Take note of any recurring mistakes (for example, misspelling a particular word, switching between US and UK English , or inconsistently capitalizing a term), and use Find and Replace to fix it throughout the document.

If you want to be confident that an important text is error-free, it might be worth choosing a professional proofreading service instead.

Editing and proofreading are different steps in the process of revising a text.

Editing comes first, and can involve major changes to content, structure and language. The first stages of editing are often done by authors themselves, while a professional editor makes the final improvements to grammar and style (for example, by improving sentence structure and word choice ).

Proofreading is the final stage of checking a text before it is published or shared. It focuses on correcting minor errors and inconsistencies (for example, in punctuation and capitalization ). Proofreaders often also check for formatting issues, especially in print publishing.

The cost of proofreading depends on the type and length of text, the turnaround time, and the level of services required. Most proofreading companies charge per word or page, while freelancers sometimes charge an hourly rate.

For proofreading alone, which involves only basic corrections of typos and formatting mistakes, you might pay as little as $0.01 per word, but in many cases, your text will also require some level of editing , which costs slightly more.

It’s often possible to purchase combined proofreading and editing services and calculate the price in advance based on your requirements.

There are many different routes to becoming a professional proofreader or editor. The necessary qualifications depend on the field – to be an academic or scientific proofreader, for example, you will need at least a university degree in a relevant subject.

For most proofreading jobs, experience and demonstrated skills are more important than specific qualifications. Often your skills will be tested as part of the application process.

To learn practical proofreading skills, you can choose to take a course with a professional organization such as the Society for Editors and Proofreaders . Alternatively, you can apply to companies that offer specialized on-the-job training programmes, such as the Scribbr Academy .

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows: 

 Annotated Bibliography Literature Review 
Purpose List of citations of books, articles, and other sources with a brief description (annotation) of each source. Comprehensive and critical analysis of existing literature on a specific topic. 
Focus Summary and evaluation of each source, including its relevance, methodology, and key findings. Provides an overview of the current state of knowledge on a particular subject and identifies gaps, trends, and patterns in existing literature. 
Structure Each citation is followed by a concise paragraph (annotation) that describes the source’s content, methodology, and its contribution to the topic. The literature review is organized thematically or chronologically and involves a synthesis of the findings from different sources to build a narrative or argument. 
Length Typically 100-200 words Length of literature review ranges from a few pages to several chapters 
Independence Each source is treated separately, with less emphasis on synthesizing the information across sources. The writer synthesizes information from multiple sources to present a cohesive overview of the topic.

What is a Literature Review?

A literature review is a critical summary and evaluation of the existing research (e.g., academic journal articles and books) on a specific topic. It is typically included as a separate section or chapter of a research paper or dissertation, serving as a contextual framework for a study. Literature reviews can vary in length depending on the subject and nature of the study, with most being about equal length to other sections or chapters included in the paper. Essentially, the literature review highlights previous studies in the context of your research and summarizes your insights in a structured, organized format. Next, let’s look at the overall purpose of a literature review.

Literature reviews are considered an integral part of research across most academic subjects and fields. The primary purpose of a literature review in your study is to:

Provide a Foundation for Current Research

Since the literature review provides a comprehensive evaluation of the existing research, it serves as a solid foundation for your current study. It’s a way to contextualize your work and show how your research fits into the broader landscape of your specific area of study.  

Define Key Concepts and Theories

The literature review highlights the central theories and concepts that have arisen from previous research on your chosen topic. It gives your readers a more thorough understanding of the background of your study and why your research is particularly significant .

Demonstrate Critical Evaluation 

A comprehensive literature review shows your ability to critically analyze and evaluate a broad range of source material. And since you’re considering and acknowledging the contribution of key scholars alongside your own, it establishes your own credibility and knowledge.

Show How Research and Methodologies Have Evolved

Another purpose of literature reviews is to provide a historical perspective and demonstrate how research and methodologies have changed over time, especially as data collection methods and technology have advanced. And studying past methodologies allows you, as the researcher, to understand what did and did not work and apply that knowledge to your own research.  

Identify Gaps in Existing Research

Besides discussing current research and methodologies, the literature review should also address areas that are lacking in the existing literature. This helps further demonstrate the relevance of your own research by explaining why your study is necessary to fill the gaps.

Support Your Argument

A good literature review should provide evidence that supports your research questions and hypothesis. For example, your study may show that your research supports existing theories or builds on them in some way. Referencing previous related studies shows your work is grounded in established research and will ultimately be a contribution to the field.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it .

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

  • To develop a theory or evaluate an existing theory
  • To summarize the historical or existing state of a research topic
  • Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

  • A research paper assigned in a course
  • A thesis or dissertation
  • A grant proposal
  • An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

  • Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

  • Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

  • Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

  • Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

  • Search for relevant literature
  • Evaluate sources
  • Identify themes, debates and gaps
  • Outline the structure
  • Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

  • Quick Run-through
  • Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

  • Demonstrate your familiarity with the topic and scholarly context
  • Develop a theoretical framework and methodology for your research
  • Position yourself in relation to other researchers and theorists
  • Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Literature review guide

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

  • Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
  • Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
  • Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
  • Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

  • Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
  • Body image, self-perception, self-esteem, mental health
  • Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

  • Your university’s library catalogue
  • Google Scholar
  • Project Muse (humanities and social sciences)
  • Medline (life sciences and biomedicine)
  • EconLit (economics)
  • Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

  • What question or problem is the author addressing?
  • What are the key concepts and how are they defined?
  • What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
  • What are the results and conclusions of the study?
  • How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
  • How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
  • What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

what is the main goal of literature review

Correct my document today

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

  • Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
  • Themes: what questions or concepts recur across the literature?
  • Debates, conflicts and contradictions: where do sources disagree?
  • Pivotal publications: are there any influential theories or studies that changed the direction of the field?
  • Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

  • Most research has focused on young women.
  • There is an increasing interest in the visual aspects of social media.
  • But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

  • Look at what results have emerged in qualitative versus quantitative research
  • Discuss how the topic has been approached by empirical versus theoretical scholarship
  • Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

  • Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
  • Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
  • Critically evaluate: mention the strengths and weaknesses of your sources.
  • Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

  • To familiarise yourself with the current state of knowledge on your topic
  • To ensure that you’re not just repeating what others have already done
  • To identify gaps in knowledge and unresolved problems that your research can address
  • To develop your theoretical framework and methodology
  • To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

  • Provide a comprehensive and updated review of the literature;
  • Explain why this review has taken place;
  • Articulate a position or hypothesis;
  • Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

  • Demonstrate how a study fills a gap in research
  • Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

  • Organizes or describes a topic
  • Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

  • It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
  • It may be too focused. Some niche studies may miss the bigger picture.
  • It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
  • It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

What is a Literature Review?

So, what is a literature review .

"A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available or a set of summaries." - Quote from Taylor, D. (n.d)."The Literature Review: A Few Tips on Conducting it".

  • Citation: "The Literature Review: A Few Tips on Conducting it"

What kinds of literature reviews are written?

Each field has a particular way to do reviews for academic research literature. In the social sciences and humanities the most common are:

  • Narrative Reviews: The purpose of this type of review is to describe the current state of the research on a specific research topic and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weaknesses, and gaps are identified. The review ends with a conclusion section that summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.
  • Book review essays/ Historiographical review essays : A type of literature review typical in History and related fields, e.g., Latin American studies. For example, the Latin American Research Review explains that the purpose of this type of review is to “(1) to familiarize readers with the subject, approach, arguments, and conclusions found in a group of books whose common focus is a historical period; a country or region within Latin America; or a practice, development, or issue of interest to specialists and others; (2) to locate these books within current scholarship, critical methodologies, and approaches; and (3) to probe the relation of these new books to previous work on the subject, especially canonical texts. Unlike individual book reviews, the cluster reviews found in LARR seek to address the state of the field or discipline and not solely the works at issue.” - LARR

What are the Goals of Creating a Literature Review?

  • To develop a theory or evaluate an existing theory
  • To summarize the historical or existing state of a research topic
  • Identify a problem in a field of research 
  • Baumeister, R.F. & Leary, M.R. (1997). "Writing narrative literature reviews," Review of General Psychology , 1(3), 311-320.

When do you need to write a Literature Review?

  • When writing a prospectus or a thesis/dissertation
  • When writing a research paper
  • When writing a grant proposal

In all these cases you need to dedicate a chapter in these works to showcase what has been written about your research topic and to point out how your own research will shed new light into a body of scholarship.

Where I can find examples of Literature Reviews?

Note:  In the humanities, even if they don't use the term "literature review", they may have a dedicated  chapter that reviewed the "critical bibliography" or they incorporated that review in the introduction or first chapter of the dissertation, book, or article.

  • UCSB electronic theses and dissertations In partnership with the Graduate Division, the UC Santa Barbara Library is making available theses and dissertations produced by UCSB students. Currently included in ADRL are theses and dissertations that were originally filed electronically, starting in 2011. In future phases of ADRL, all theses and dissertations created by UCSB students may be digitized and made available.

Where to Find Standalone Literature Reviews

Literature reviews are also written as standalone articles as a way to survey a particular research topic in-depth. This type of literature review looks at a topic from a historical perspective to see how the understanding of the topic has changed over time. 

  • Find e-Journals for Standalone Literature Reviews The best way to get familiar with and to learn how to write literature reviews is by reading them. You can use our Journal Search option to find journals that specialize in publishing literature reviews from major disciplines like anthropology, sociology, etc. Usually these titles are called, "Annual Review of [discipline name] OR [Discipline name] Review. This option works best if you know the title of the publication you are looking for. Below are some examples of these journals! more... less...

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

How to write a literature review in 6 steps

Literature review for thesis

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

  • Identify the main purpose of the literature review.
  • Do extensive research.
  • Evaluate and select relevant sources.
  • Analyze the sources.
  • Plan a structure.
  • Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

  • How many sources do I need to include?
  • What types of sources should I review?
  • Should I evaluate the sources?
  • Should I summarize, synthesize or critique sources?
  • Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

  • Google Scholar
  • Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

  • authors' names
  • page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Paperpile reference manager

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

  • Read it critically.
  • Look for the main arguments.
  • Take notes as you read.
  • Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

  • What are the key terms, concepts and problems addressed by the author?
  • How is this source relevant for my specific topic?
  • How is the article structured? What are the major trends and findings?
  • What are the conclusions of the study?
  • How are the results presented? Is the source credible?
  • When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
  • Does the study help me understand the topic better?
  • Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

  • Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
  • Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
  • Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
  • Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

  • An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
  • A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
  • A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

➡️ If your literature review is part of a longer paper, visit our guide on what is a research paper for additional tips.

➡️ How to write a literature review in 3 steps

➡️ How to write a literature review in 30 minutes or less

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

Questions to Consider

B. In some fields or contexts, a literature review is referred to as the introduction or the background; why is this true, and does it matter?

The elements of a literature review • The first step in scholarly research is determining the “state of the art” on a topic. This is accomplished by gathering academic research and making sense of it. • The academic literature can be found in scholarly books and journals; the goal is to discover recurring themes, find the latest data, and identify any missing pieces. • The resulting literature review organizes the research in such a way that tells a story about the topic or issue.

The literature review tells a story in which one well-paraphrased summary from a relevant source contributes to and connects with the next in a logical manner, developing and fulfilling the message of the author. It includes analysis of the arguments from the literature, as well as revealing consistent and inconsistent findings. How do varying author insights differ from or conform to previous arguments?

Language in Action

A. How are the terms “critique” and “review” used in everyday life? How are they used in an academic context?

what is the main goal of literature review

In terms of content, a literature review is intended to:

• Set up a theoretical framework for further research • Show a clear understanding of the key concepts/studies/models related to the topic • Demonstrate knowledge about the history of the research area and any related controversies • Clarify significant definitions and terminology • Develop a space in the existing work for new research

The literature consists of the published works that document a scholarly conversation or progression on a problem or topic in a field of study. Among these are documents that explain the background and show the loose ends in the established research on which a proposed project is based. Although a literature review focuses on primary, peer -reviewed resources, it may begin with background subject information generally found in secondary and tertiary sources such as books and encyclopedias. Following that essential overview, the seminal literature of the field is explored. As a result, while a literature review may consist of research articles tightly focused on a topic with secondary and tertiary sources used more sparingly, all three types of information (primary, secondary, tertiary) are critical.

The literature review, often referred to as the Background or Introduction to a research paper that presents methods, materials, results and discussion, exists in every field and serves many functions in research writing.

Review and Reinforce

Two common approaches are simply outlined here. Which seems more common? Which more productive? Why? A. Forward exploration 1. Sources on a topic or problem are gathered. 2. Salient themes are discovered. 3. Research gaps are considered for future research. B. Backward exploration 1. Sources pertaining to an existing research project are gathered. 2. The justification of the research project’s methods or materials are explained and supported based on previously documented research.

What Is A Literature Review?

A plain-language explainer (with examples).

By:  Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)

If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.

Literature Review 101

  • What (exactly) is a literature review
  • What’s the purpose of the literature review chapter
  • How to find high-quality resources
  • How to structure your literature review chapter
  • Example of an actual literature review

What is a literature review?

The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of  reviewing the literature  – i.e. sourcing and reading through the existing research relating to your research topic. The second is the  actual chapter  that you write up in your dissertation, thesis or research project. Let’s look at each of them:

Reviewing the literature

The first step of any literature review is to hunt down and  read through the existing research  that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then  summarise and catalogue these  for easy reference when you write up your literature review chapter. 

The literature review chapter

The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an  overview of the key literature  that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an  integrated review of the state of knowledge  around your research topic. 

Starting point for the literature review

What’s the purpose of a literature review?

The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:

Purpose #1 – Demonstrate your topic knowledge

The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you  know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be  more than just a summary  of who said what – it needs to integrate the existing research to  show how it all fits together  and what’s missing (which leads us to purpose #2, next). 

Purpose #2 – Reveal the research gap that you’ll fill

The second function of the literature review chapter is to  show what’s currently missing  from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that  your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.  

Purpose #3 – Lay the foundation for your conceptual framework

The third function of the literature review is to form the  basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review. 

For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut! 

So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework. 

Purpose #4 – To inform your methodology

The fourth function of the literature review is to  inform the choice of methodology  for your own research. As we’ve  discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.

So, when you’re reviewing the literature, you’ll need to  pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to  “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales.

How do I find articles for my literature review?

Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is  built on credible research . 

We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the  most popular pieces of research  are in your field.

One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes  it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites. 

Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to  ResearchGate , which is another great source for existing research. 

Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer.

what is the main goal of literature review

How should I structure my literature review?

Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.

You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.

In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .

Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.

A good literature review should synthesise the existing research in relation to the research aims, not simply summarise it.

Example of a literature review

In the video below, we walk you through a high-quality literature review from a dissertation that earned full distinction. This will give you a clearer view of what a strong literature review looks like in practice and hopefully provide some inspiration for your own.

Conducting your literature review 

by Susanne Hempel

The purpose of a literature review

Conducting a literature review is a means of demonstrating the  author’s knowledge  about a particular field of study, including vocabulary, theories, key variables and phenomena, and its methods and history. Conducting a literature review also informs the student of the  influential researchers and research groups  in the field (Randolph, 2009).

Literature reviews:

  • report on  knowledge and ideas  that have been established on a particular topic, including their  strengths and weaknesses  while they allow you to discover the agreed academic opinion on the topic while at the same time letting you find out the disagreements on the same subject.
  • position your research project within the body of literature and thereby  provide perspective  for the reader.
  • demonstrate  your knowledge  of the subject area.
  • determine what each source contributes to the topic.
  • understand the  relationship between the various contributions , identify and (if possible) resolve contradictions, and determine gaps or unanswered questions.
  • justify your  choice of research design ; for instance, your choice of qualitative over quantitative approaches, or your method of data analysis.
  • clarify how your work fills a  gap  in the scholarly literature.

Writing a literature review also allows you to:

  • gain expertise in the ability to scan the literature on a particular topic efficiently, and
  • hone your skills in identifying and analysing unbiased and valid data on various topics or fields of study.

The Research Proposal

83 Components of the Literature Review

Krathwohl (2005) suggests and describes a variety of components to include in a research proposal.  The following sections present these components in a suggested template for you to follow in the preparation of your research proposal.

Introduction

The introduction sets the tone for what follows in your research proposal – treat it as the initial pitch of your idea.  After reading the introduction your reader should:

  • Understand what it is you want to do;
  • Have a sense of your passion for the topic;
  • Be excited about the study´s possible outcomes.

As you begin writing your research proposal it is helpful to think of the introduction as a narrative of what it is you want to do, written in one to three paragraphs.  Within those one to three paragraphs, it is important to briefly answer the following questions:

  • What is the central research problem?
  • How is the topic of your research proposal related to the problem?
  • What methods will you utilize to analyze the research problem?
  • Why is it important to undertake this research? What is the significance of your proposed research?  Why are the outcomes of your proposed research important, and to whom or to what are they important?

Note : You may be asked by your instructor to include an abstract with your research proposal.  In such cases, an abstract should provide an overview of what it is you plan to study, your main research question, a brief explanation of your methods to answer the research question, and your expected findings. All of this information must be carefully crafted in 150 to 250 words.  A word of advice is to save the writing of your abstract until the very end of your research proposal preparation.  If you are asked to provide an abstract, you should include 5-7 key words that are of most relevance to your study. List these in order of relevance.

Background and significance

The purpose of this section is to explain the context of your proposal and to describe, in detail, why it is important to undertake this research. Assume that the person or people who will read your research proposal know nothing or very little about the research problem.  While you do not need to include all knowledge you have learned about your topic in this section, it is important to ensure that you include the most relevant material that will help to explain the goals of your research.

While there are no hard and fast rules, you should attempt to address some or all of the following key points:

  • State the research problem and provide a more thorough explanation about the purpose of the study than what you stated in the introduction.
  • Present the rationale for the proposed research study. Clearly indicate why this research is worth doing.  Answer the “so what?” question.
  • Describe the major issues or problems to be addressed by your research. Do not forget to explain how and in what ways your proposed research builds upon previous related research.
  • Explain how you plan to go about conducting your research.
  • Clearly identify the key or most relevant sources of research you intend to use and explain how they will contribute to your analysis of the topic.
  • Set the boundaries of your proposed research, in order to provide a clear focus. Where appropriate, state not only what you will study, but what will be excluded from your study.
  • Provide clear definitions of key concepts and terms. As key concepts and terms often have numerous definitions, make sure you state which definition you will be utilizing in your research.

Literature Review

This is the most time-consuming aspect in the preparation of your research proposal and it is a key component of the research proposal. As described in Chapter 5 , the literature review provides the background to your study and demonstrates the significance of the proposed research. Specifically, it is a review and synthesis of prior research that is related to the problem you are setting forth to investigate.  Essentially, your goal in the literature review is to place your research study within the larger whole of what has been studied in the past, while demonstrating to your reader that your work is original, innovative, and adds to the larger whole.

As the literature review is information dense, it is essential that this section be intelligently structured to enable your reader to grasp the key arguments underpinning your study. However, this can be easier to state and harder to do, simply due to the fact there is usually a plethora of related research to sift through. Consequently, a good strategy for writing the literature review is to break the literature into conceptual categories or themes, rather than attempting to describe various groups of literature you reviewed.  Chapter V, “ The Literature Review ,” describes a variety of methods to help you organize the themes.

Here are some suggestions on how to approach the writing of your literature review:

  • Think about what questions other researchers have asked, what methods they used, what they found, and what they recommended based upon their findings.
  • Do not be afraid to challenge previous related research findings and/or conclusions.
  • Assess what you believe to be missing from previous research and explain how your research fills in this gap and/or extends previous research

It is important to note that a significant challenge related to undertaking a literature review is knowing when to stop.  As such, it is important to know how to know when you have uncovered the key conceptual categories underlying your research topic.  Generally, when you start to see repetition in the conclusions or recommendations, you can have confidence that you have covered all of the significant conceptual categories in your literature review.  However, it is also important to acknowledge that researchers often find themselves returning to the literature as they collect and analyze their data.  For example, an unexpected finding may develop as one collects and/or analyzes the data and it is important to take the time to step back and review the literature again, to ensure that no other researchers have found a similar finding.  This may include looking to research outside your field.

This situation occurred with one of the authors of this textbook´s research related to community resilience.  During the interviews, the researchers heard many participants discuss individual resilience factors and how they believed these individual factors helped make the community more resilient, overall.  Sheppard and Williams (2016) had not discovered these individual factors in their original literature review on community and environmental resilience. However, when they returned to the literature to search for individual resilience factors, they discovered a small body of literature in the child and youth psychology field. Consequently, Sheppard and Williams had to go back and add a new section to their literature review on individual resilience factors. Interestingly, their research appeared to be the first research to link individual resilience factors with community resilience factors.

Research design and methods

The objective of this section of the research proposal is to convince the reader that your overall research design and methods of analysis will enable you to solve the research problem you have identified and also enable you to accurately and effectively interpret the results of your research. Consequently, it is critical that the research design and methods section is well-written, clear, and logically organized.  This demonstrates to your reader that you know what you are going to do and how you are going to do it.  Overall, you want to leave your reader feeling confident that you have what it takes to get this research study completed in a timely fashion.

Essentially, this section of the research proposal should be clearly tied to the specific objectives of your study; however, it is also important to draw upon and include examples from the literature review that relate to your design and intended methods.  In other words, you must clearly demonstrate how your study utilizes and builds upon past studies, as it relates to the research design and intended methods.  For example, what methods have been used by other researchers in similar studies?

While it is important to consider the methods that other researchers have employed, it is equally important, if not more so, to consider what methods have not been employed but could be.  Remember, the methods section is not simply a list of tasks to be undertaken. It is also an argument as to why and how the tasks you have outlined will help you investigate the research problem and answer your research question(s).

Tips for writing the research design and methods section:

  • Specify the methodological approaches you intend to employ to obtain information and the techniques you will use to analyze the data.
  • Specify the research operations you will undertake and he way you will interpret the results of those operations in relation to the research problem.
  • Go beyond stating what you hope to achieve through the methods you have chosen. State how you will actually do the methods (i.e. coding interview text, running regression analysis, etc.).
  • Anticipate and acknowledge any potential barriers you may encounter when undertaking your research and describe how you will address these barriers.
  • Explain where you believe you will find challenges related to data collection, including access to participants and information.

Preliminary suppositions and implications

The purpose of this section is to argue how and in what ways you anticipate that your research will refine, revise, or extend existing knowledge in the area of your study. Depending upon the aims and objectives of your study, you should also discuss how your anticipated findings may impact future research.  For example, is it possible that your research may lead to a new policy, new theoretical understanding, or a new method for analyzing data?  How might your study influence future studies?  What might your study mean for future practitioners working in the field?  Who or what may benefit from your study?  How might your study contribute to social, economic, environmental issues?  While it is important to think about and discuss possibilities such as these, it is equally important to be realistic in stating your anticipated findings.  In other words, you do not want to delve into idle speculation.  Rather, the purpose here is to reflect upon gaps in the current body of literature and to describe how and in what ways you anticipate your research will begin to fill in some or all of those gaps.

The conclusion reiterates the importance and significance of your research proposal and it provides a brief summary of the entire proposed study.  Essentially, this section should only be one or two paragraphs in length. Here is a potential outline for your conclusion:

  • Discuss why the study should be done. Specifically discuss how you expect your study will advance existing knowledge and how your study is unique.
  • Explain the specific purpose of the study and the research questions that the study will answer.
  • Explain why the research design and methods chosen for this study are appropriate, and why other design and methods were not chosen.
  • State the potential implications you expect to emerge from your proposed study,
  • Provide a sense of how your study fits within the broader scholarship currently in existence related to the research problem.

As with any scholarly research paper, you must cite the sources you used in composing your research proposal.  In a research proposal, this can take two forms: a reference list or a bibliography.  A reference list does what the name suggests, it lists the literature you referenced in the body of your research proposal.  All references in the reference list, must appear in the body of the research proposal.  Remember, it is not acceptable to say “as cited in …”  As a researcher you must always go to the original source and check it for yourself.  Many errors are made in referencing, even by top researchers, and so it is important not to perpetuate an error made by someone else. While this can be time consuming, it is the proper way to undertake a literature review.

In contrast, a bibliography , is a list of everything you used or cited in your research proposal, with additional citations to any key sources relevant to understanding the research problem.  In other words, sources cited in your bibliography may not necessarily appear in the body of your research proposal.  Make sure you check with your instructor to see which of the two you are expected to produce.

Overall, your list of citations should be a testament to the fact that you have done a sufficient level of preliminary research to ensure that your project will complement, but not duplicate, previous research efforts. For social sciences, the reference list or bibliography should be prepared in American Psychological Association (APA) referencing format. Usually, the reference list (or bibliography) is not included in the word count of the research proposal. Again, make sure you check with your instructor to confirm.

Metrics details

The prevailing patient safety strategies in suicide prevention are suicide risk assessments and retrospective reviews, with emphasis on minimising risk and preventing adverse events. Resilient healthcare focuses on how everyday clinical practice succeeds and emphasises learning from practice, not from adverse events. Yet, little is known about resilient practices for suicidal inpatients. The aim of the study is to draw upon the perspectives of patients and healthcare professionals to inform the conceptual development of resilient practices in inpatient suicide prevention.

A narrative synthesis was conducted of findings across patients and healthcare professionals derived from a qualitative case study based on interviews with patients and healthcare professionals in addition to a systematic literature review.

Three sub-themes categorise resilient practices for healthcare professionals and for patients hospitalised with suicidal behaviour: 1) interactions capturing non-verbal cues; 2) protection through dignity and watchfulness; and 3) personalised approaches to alleviate emotional pressure. The main theme, the establishment of relationships of trust in resilient practices for patients in suicidal crisis, is the foundation of their communication and caring.

Clinical practice for patients hospitalised with suicidal behaviour has characteristics of complex adaptive systems in terms of dynamic interactions, decision-making under uncertainty, tensions between goals solved through trade-offs, and adaptations to patient variability and interpersonal needs. To improve the safety of patients hospitalised with suicidal behaviour, variability in clinical practice should be embraced.

Peer Review reports

Introduction

Our understanding of patient safety for patients hospitalised during a suicidal crisis is limited [ 1 ]. In a systematic review of the literature, Thibaut et al. found [ 2 ] few peer-reviewed empirical studies on patient safety and suicidal behaviour. The literature drawing on the interdisciplinary field of safety science in suicide prevention is particularly thin. Safety science has provided us with the key message that different models affect our understanding of adverse events and thereby have a vast impact on learning and to where we direct our safety measures [ 3 , 4 , 5 ].

According to Hollnagel, the traditional view of safety, referred to here as safety-I is defined by the absence of accidents and incidents [ 6 ]. Consequently, the focus of safety management and research has been on learning about unsafe systems while minimising the number of adverse events [ 7 ]. Methods such as root cause analysis, incident reporting and checklists to reduce healthcare professionals’ (HCPs’) errors are examples of the traditional approach to patient safety [ 7 , 8 ]. Likewise, in a scoping review of patient safety strategies in psychiatry, Svensson found that these measures are mainly intended to prevent adverse events by focusing on failure and ensuring compliance to procedures [ 9 ]. Across countries, clinical practice guidelines on suicide prevention include restricting lethal means, assessing evidence-based suicide risk factors and suicidal intent along with recommended treatment and post-intervention recommendation [ 10 ]. Nevertheless, while the clinical field is moving in the direction of a systematic suicide management system [ 11 , 12 , 13 ], patient safety strategies in suicide prevention have been criticised as excessively focused on harm reduction (e.g. suicide risk assessment) [ 14 , 15 , 16 ].

Retrospective reviews of suicide incidents have focused on deficiencies in the interface between healthcare professionals (HCPs) and patients [ 14 , 17 , 18 ]. In hindsight, suicide investigations have often concluded that an improved risk assessment could have led to a different outcome [ 14 , 17 , 18 ]. Nonetheless, suicidal outcomes cannot be predicted at the individual level [ 19 , 20 , 21 ]. The fallacies of perceiving HCPs in the sharp end of the system as the main causes of the patient suicide are abundant; HCPs are the secondary victims of patient suicides; learning outcomes at the system level are limited; and the complexity of making the decisions regarding suicide risk, and the flexibility required for HCPs to adapt treatment to patients is ignored [ 14 , 17 , 18 ].

A safety-I approach narrows the gap between what HCPs do in practice and their procedures for that practice [ 6 ]. Patient safety in psychiatry has emphasised improving staff compliance to safety-I procedures [ 9 ]. At the same time, there is no single means of preventing inpatient suicides, and practice is characterised by uncertainty and complexity. The lack of a solution relates to the aetiological heterogeneity of suicidal patients, and the need to understand and approach each patient differently [ 22 ]. Uncertainty is also related to the ethical challenges of assigning suicidal patients to a control non-treatment condition to determine whether specific interventions, such as constant observation, have a preventive effect [ 23 ]. As such, no study has examined whether being under observation reduces the number of suicide attempt or deaths [ 24 ]. Clinical decision-making regarding suicide risk involves a high degree of uncertainty. Despite considerable research, instruments used to assign patients to high-risk groups do not enable HCPs to predict which of those patients will die by suicide [ 19 , 25 , 26 ]. There are therefore many limitations to the safety-I approach in the face of healthcare practices.

The field of resilient healthcare (RHC) has sought insight into healthcare practices and the ways in which everyday clinical practice succeeds [ 27 , 28 , 29 ]. Hollnagel [ 6 ] has defined safety-II as ‘the ability to succeed under expected and unexpected conditions alike, so that the number of intended and acceptable outcomes (in other words, everyday activities) is as high as possible’ (Hollnagel, 2014, p. 134). RHC draws on theories from safety science in which healthcare is recognised as a complex adaptive system (CAS) [ 27 , 28 ]. Wiig et al. [ 30 ] describe resilience in healthcare as ‘…the capacity to adapt to challenges and changes at different system levels to maintain high-quality care’ (p. 6). Adaptation is thus seen as the central tenet of RHC and might come in many forms and at multiple levels, for example as HCPs’ capacity to adjust their reasoning and clinical measures based on patient conditions and/or work-related conditions.

Mental health services have been conceptualised as a CAS by Ellis, Churruca and Braithwaite [ 31 ], in which patients and HCPs interact across care levels, and constantly adjust practice to the patient, caregivers, policies, research and standardised and evidence-based treatment. Although most RHC studies have used HCPs as the main source of data on healthcare resilience, patients and family may also be sources [ 32 , 33 ]. Quinlivan et al. [ 34 ] emphasise the importance of patient perspectives when applying an RHC approach to suicide prevention to better grasp the patient vulnerabilities and the individual differences specific to this field. However, patients have not been used extensively as sources of knowledge in RHC [ 35 , 36 ]. Furthermore, few empirical studies have adopted RHC perspectives to suicide prevention [ 37 , 38 , 39 ], and none have incorporated patients’ perspectives. This synthesis of an in-depth qualitative case study applying RHC to suicide prevention can fill this gap. Therefore, the aim of this study was to draw upon the perspectives of patients and healthcare professionals to inform the conceptual development of resilient practices in inpatient suicide prevention.

A narrative synthesis was conducted of findings across two embedded units of analysis: the experiences of patients and the experiences of HCPs (Table 1 ) [ 40 ]. The original data consisted of three samples collected through a multi-method case study approach [ 40 ] consisting of a systematic review of 20 peer-reviewed articles published between 1999 and 2016 on patient experiences of being hospitalised in a psychiatric ward or facility during a suicidal crisis (sample 1) [ 41 ]; individual interviews with 18 patients hospitalised during a suicidal crisis (sample 2) [ 42 ]; and focus group and individual interviews with 35 HCPs responsible for the care of suicidal patients (sample 3) [ 43 ]. The methods of the case study are described in a published study protocol [ 44 ] and the first author’s PhD thesis [ 45 ]. Interview guides have been previously published, see supplemental file 2 in Berg et al. 2020a [ 46 ] and additional file 1 in Berg et al. 2020b [ 47 ].

The literature review (sample 1) followed a systematic approach according to the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses [ 48 ]. Systematic searches were conducted in the MEDLINE, Academic Search Premier, CINAHL, SOCINDEX and PsycINFO databases, identifying 20 qualitative studies on suicidal patients and their psychiatric in-patient care experiences. These studies were systematically reviewed according to PRISMA, subjected to quality appraisals, and synthesized by using thematic analysis [ 49 , 50 ]. The included studies had a total of 311 patients (see Table 2 ).

All individual interviews followed a semi-structured interview guide and were conducted by SHB face to face in a room close to the hospital ward. Focus groups were conducted with a moderator (SHB/KR) and a co-moderator (SHB/MA). Sample 3 followed a sequential triangulation, with the first data set (focus groups) informing the nature of the second (individual interviews) [ 51 ]. All interviews were audio-recorded, transcribed verbatim, coded and followed the systematic qualitative analysis methods of thematic analysis [ 50 ] and content analysis [ 52 ], with a phenomenological hermeneutical approach [ 53 ].

The setting for the empirical studies (sample 2, sample 3) was a university hospital in Norway. We used purposeful sampling to recruit suicidal patients and HCPs working in open or locked wards in specialised mental healthcare facilities for adults. Participants were recruited from nine wards. Locked wards specialised in affective disorders ( n  = 2) or acute care ( n  = 2) while open wards specialised in rehabilitation ( n  = 3) or short-time stabilisation during a crisis ( n  = 2). Fifty-three individuals (patients and HCPs) participated in the empirical studies. All patient participants had active suicidal ideation during inpatient care, nine had recently attempted suicide prior to admission to mental healthcare, see Table 2 (sample 1 and 2).

The HCPs sample included both novices and experienced participants from all professional groups, see Table 3 (sample 3).

Two patients who were invited to participate declined because of their mental state. No HCPs refused to participate. None dropped out. Five patients had follow-up interview within a week of the first interview, which followed the same interview guide.

The Norwegian suicide context

Preventing suicides during inpatient care is a high priority for patient safety in mental health. In Norway, the national guidelines for the prevention of suicides in mental healthcare [ 54 ] outline practices that managers and HCPs in specialised mental healthcare are required to follow. In addition, checklists have been used in the management of suicide risk [ 55 ]. Suicide rates have remained relatively stable in Norway, with approximately 12.1 suicides per 100 000 inhabitants in 2020 [ 56 ], which is slightly higher than the global suicide rate (11.4 per 100 000 inhabitants in 2020 [ 57 ]. Approximately 650 individuals die from suicide in Norway each year [ 58 ], and there are approximately 3500–7500 suicide attempts annually [ 59 ]. Walby et al. [ 60 ] found that 67% of the individuals in Norway who died by suicide within a year of last contact with mental health services had been hospitalised at least once in the year preceding their death. On average, 25 suicides (SD = 4,9) occurred during inpatient care each year in Norway in the period 2008–2015. This is a relatively low proportion (13%) of the total number of suicides conducted by patients receiving specialised mental healthcare services, meaning that most suicides occur in the outpatient care [ 60 ].

Ethical considerations

The case study was approved by the Western Regional Ethics Committee of Norway (REC 2016/34). All participants provided voluntary informed and written consent. Patients were interviewed during hospitalisation and all of them were under the care of specialised HCPs. None of the researchers had a role as a clinician or manager in any of the seven units included in the study or had prior established relationships with the participants. Participants were informed of the rationale for the research: to get insight into safe clinical practices for suicidal patients.

A narrative synthesis was conducted across methods and samples to find common themes reflecting both patients’ and HCPs’ perspectives, using the four stages of data synthesis as proposed by Whittemore and Knafl [ 40 ]. The narrative synthesis was a re-analysis of the work presented in the first author’s PhD thesis [ 45 ]. In the first stage, the primary sources were divided into two subgroups: patients and HCPs. In the second stage, the main findings related to perspectives on resilient practices were extracted from the primary sources and coded inductively. In the third stage, tables were used to display the codes to visualise patterns and relationship within and across primary data. Categories relating to both the patients’ and the HCPs’ perspectives were constructed by compiling codes with shared meaning. In the fourth stage, data were organised into meaningful patterns with themes and sub-themes under an overarching main theme.

This narrative synthesis synthesised patients’ experiences and the HCPs’ experiences in the context of inpatient suicide prevention. The main theme, relationships of trust in resilient practices for patients in suicidal crisis, is the foundation of their communication and caring. The main theme was described by three sub-themes which illuminate three sets of relationships: interactions capturing non-verbal cues, protection through dignity and watchfulness, and personalised approaches to alleviate emotional pressure. Table 4 depicts the main theme, the three sub-themes and categories related to the patient and HCPs perspective and how the three samples form the three themes.

The main theme, relationships of trust in resilient practices for patients in suicidal crisis reflected that resilient practices depended on trust between patients and HCPs, and that HCPs need alliances to establish trusting relationships with the patients. Trust is a precondition for resilient practices to adapt protection, treatment, and care to the needs of suicidal patients.

Suicidal patients experienced the relationship to the HCPs as essential for a feeling of safety during inpatient care. They felt safe when they met someone who cared, validated their feelings and respected them as human beings. Trusting and familiar relationships with HCPs gave them predictability in terms of how their suicidal behaviour would be understood and treated. Trust is relevant to findings involving patients in vulnerable situations: being externally controlled, talking about suicide and relieving emotional pressure.

HCPs experienced personal uncertainty in working with patients in suicidal crisis. They feared losing a patient to suicide while under their care, and they feared being held responsible by the health authorities and the hospital management. HCPs noted that their colleagues’ trust and support were necessary to manage uncertainty in clinical practice. HCPs formed and adapted their informal networks in response to the lack of formal support systems. Without support that could help HCPs cope with the uncertainty of working with suicidal patients, HCPs resorted to fear-based defensive practices to avoid blame and responsibility, which took time and focus away from the personalised activities with patients. However, social support and clinical supervision helped to counteract the impact of personal uncertainty in the patient contact.

As such, resilient practices did not merely depend on strengthening the HCPs’ ability to establish trusting relationships with the patients, but also on ensuring that HCPs had reliable support systems.

Interactions capturing non-verbal cues

The resilient practice interactions capturing non-verbal cues described the interaction between the patient and the HCPs in the detection of suicidal crisis. Suicidal crisis was apparent not only in what patients did and did not say, but also in their body language and affect, as exemplified in Table 5 .

Many of the patients expressed a struggle to communicate suicidal ideations during suicide risk assessment and acute suicidal crisis in the ward. They also experienced being recognised by HCPs who were attentive to their body language and to changes in their mental state. Patients noted that when their HCPs took a genuine personal interest in them, they were less likely to attempt suicide during inpatient care (sample 2).

HCPs attended to multiple sources of information to make sense of suicidal behaviour including the non-verbal cues. The more experienced HCPs claimed that the formal procedures for assessing risk were not helpful during risk assessment, as the list did not take the context-sensitive and non-verbal behaviour into account. They improved their understanding by establishing relational contact with the patient and triangulating several sources of information, including the patients’ verbal and non-verbal cues, mental state, diagnosis and their own ‘gut feeling’. Expertise increased the complexity and the number of information sources that were considered to clarify the picture. Furthermore, HCPs improved their situational awareness of the patients’ suicide risk by seeking other perspectives, which involved reflecting with the patient, bringing other HCPs into conversations with the patient and discussing the case with more experienced colleagues and with doctors on call (sample 3).

Interactions capturing non-verbal cues were grounded in relationships of trust. Patients described a trusted HCPs as someone who connected with them and understood their verbal and non-verbal cues of suicidal crisis (sample 2). When trusted HCPs were unavailable, patients in suicidal deterioration felt unsafe and vulnerable (sample 2). HCPs used experience and emotionally based competence to anticipate suicidal acts, and they perceived this process was strengthened by developing bonds of trust with the patient (sample 3).

Protection through dignity and watchfulness

The resilient practice protection through dignity and watchfulness described the physical protection of patients with suicidal behaviour as a relational and interacting practice, depending on adaptations to ensure that each patient was physically protected, yet connected, as exemplified in Table 6 .

Suicidal patients expressed a need for a safe balance among multiple needs for protection. Findings reflected that suicidal patients needed to be physically protected from death during suicidal crisis while feeling connected with the HCPs during observation. Lack of connection during observation made some patients feel unsafe and thereby intensified their suicidal behaviour (sample 1).

Furthermore, patients’ need for protection during suicidal crisis changed in the course of hospitalisation and depended on a) their ability to establish relations with their HCPs and verbalise their needs; b) their need to withdraw from and master stressors in the outside world; c) their need for closeness to or distance from the HCPs; and d) their need for external control (e.g., locked doors) or internal control (e.g,. impulse control). Thus, resilient practices were experienced when protection of the individual balanced his or her multiple needs (sample 2).

HCPs were adjusting protection of the patient through dynamic trade-offs between under- and over-protection. While the formal procedure described observation as either constant or intermittent (5-, 10-, 30-min) intervals of observation, HCPs were constantly adjusting the observation practice towards the patient. Instead of watching the patients from a distance, they engaged with them, treated them with dignity, but kept an eye on them. Furthermore, HCPs were constantly balancing the physical protection of the patient from suicidal impulses with the risk of over-protection while increasing the patient’s sense of independence at the risk of under-protection. Thus, safe levels of protection were trade-offs between short- and long-term goals in care (sample 3).

Protection through dignity and watchfulness was rooted in relationships of trust. The link between feeling safe and being safe was vital for suicidal patients; their physical safety could not be guaranteed if they felt vulnerable (sample 1). Lack of support from HCPs when patients were under constant observation made patients feel alienated and objectified, their suicidality worsened, and it supported their perception of worthlessness and the sense that no one cared about them (sample 1). Trust that HCPs were acting in the patients’ best interest was a prerequisite for patients’ feelings of safety when they were under external control (sample 2). Likewise, HCP adapted their approaches to protection to ensure patients understood they were acting in their best interest through explaining why doors were locked, and why they had to give away some personal belongings (sample 2) and treating patients with dignity during observation (sample 3).

Personalised approaches to alleviate emotional pressure

The resilient practice personalised approaches to alleviate emotional pressure described the adaptation of treatment and safety procedures that are made to meet individual patients’ needs. Patients experienced less emotional pressure and their suicidal impulses diminished as a result (Table 7 ).

Patients emphasised that regaining a sense of control through coping with symptoms and difficulties was vital when they were having a suicidal crisis. Perception of control through gaining insight, coping with underlying difficulties and symptoms, and being prepared for discharge were essential for suicidal patients’ feeling of safety during inpatient care (sample 1).

Personalised approaches to treatment addressed patients’ underlying mental health issues and stressors. This kind of treatment relieved their emotional pressure, whether it involved medications and physical protection to reduce psychotic symptoms or resolving financial issues to instill hope and a sense of relief from depression. These strategies helped suicidal patients feel safe from suicidal impulses through strengthening their sense of internal control. Talking about suicide also alleviated patients’ individual stressors, symptoms, or emotional pain. When conversations about suicide opened with standard questions and answers about suicide risk, they lost their therapeutic benefit and could evoke feelings of shame and hopelessness. Patients achieved a sense of control in a variety of ways. In the acute phases of their suicidal crisis, some patients wanted external control over their suicidal impulses because physical protection convinced them that they could not harm themselves (sample 2).

HCPs targeted underlying issues by creating individual clinical pathways for suicidal patients. HCPs considered individualised approaches to be important in conversations about suicidal ideations; however, they experienced competing goals between documenting risk and understanding patients as individuals in practice (sample 3).

Personalised approaches to alleviating emotional pressure are rooted in relationships of trust. Seeking help and talking about suicide place a suicidal patient in a highly vulnerable position. If they could not trust their HCPs, some patients withdrew from talking about suicidal ideations and stopped seeking help (sample 2). Likewise, HCPs perceived trusted relationships as a condition for honest responses in suicide risk assessment and described setting aside checklists and forms to prioritise making a trusting bond, a safe atmosphere and engaging with the patients in a dialogue when talking about suicide (sample 3).

We identified three sub-themes categorising resilient practices for patients hospitalised with suicidal behaviour and HCPs: interactions capturing non-verbal cues, protection through dignity and watchfulness, and personalised approaches to alleviate emotional pressure. All three are grounded in relationships of trust in resilient practices for patients in suicidal crisis. These resilient practices outline a safety-II perspective in inpatient care of suicidal patients, which is based on culturally situated knowledge which cannot be generalised to all inpatient settings [ 61 ]. However, theoretical conceptualisation can be made regarding the understanding of safety for the suicidal patient, from a resilience perspective [ 61 ]. Above all, the perspective of resilience provides insight into the system complexity of suicide prevention, and how patients and HCPs cope with challenges and changes [ 28 , 62 ].

The complexity of clinical practice for patients hospitalised with suicidal behaviour

The shared understanding of resilient practices offers insight into clinical practice for patients hospitalised with suicidal behaviour. This clinical practice has the characteristics of a CAS [ 27 , 28 , 63 , 64 ], which has been previously presented in the first author’s PhD thesis [ 45 ].

Interactions capturing non-verbal cues of suicidal inpatients reflect uncertainty in clinical decision-making. The findings correspond with previous studies suggesting that caring for suicidal patients involves uncertainty [ 65 , 66 , 67 ] and expand the literature by showing that making sense of suicidal behaviour requires the comprehension of information ‘beyond the spoken word’, using intuition along with other sources of information (e.g. diagnosis, mental state, medical journal, individual risk factors) [ 68 , 69 ]. To attempt anticipating suicide, and to adapt and respond to the suicidal crisis of patients in the wards, HCPs apply multiple sensemaking strategies to improve their situational awareness [ 70 , 71 ]. The complexity and ambiguity of the cues involved in making sense of suicidal behaviour highlight that it is difficult to standardise screening questions or limit a set of cues to look for (proximal risk factors) in the setting of inpatient suicide prevention with high specificity [ 72 ]. Furthermore, suicide prediction models are imprecise [ 21 ], the evidence does not support the use of risk scales in suicide risk assessment [ 20 , 73 ], and there is no support for the use of clinical intuition as the sole source of suicide prediction, which leaves HCPs with limited support for their clinical decision making. This study supports that ‘work as done’ of suicide risk assessments involves multiple strategies to make sense of uncertainty, which is a characteristic of decision making in complex high-risk and ambiguous work settings [ 70 , 74 , 75 , 76 ].

Protection through dignity and watchfulness, and personalised approaches to alleviate emotional pressure emphasise that there is no one-size-fits-all approach to the protection and treatment of suicidal patients. Instead, practice relies on interpersonal and context-sensitive adaptations to ensure protection is safe [ 28 , 30 , 31 , 77 ]. Furthermore, clinical practice for suicidal patients is characterised by multiple conflicting goals which must be resolved by making trade-offs between higher- and lower-level goals [ 78 ], e.g., preventing immediate harm and working towards long-term health goals. Dynamic interactions and adaptations to ensure safe work are characteristics of a complex adaptive system [ 27 , 28 , 63 , 64 ].

Relationships of trust in resilient practices for patients in suicidal crisis reflect that the complexity in clinical practice is characterised by the establishment of psychological and relational safety, which is only created through personalised and trusted relationships. Personalised relationships are the core characteristic of mental healthcare as a complex adaptive systems [ 31 ].

In a CAS there will be unpredictable consequences of standardised patient safety interventions due to the need for adaptations in clinical practice to ensure safe outcomes. For those designing patient safety interventions at the blunt end of the system, deviations from the procedure may be perceived as an error to be corrected [ 6 ]. However, while errors arise from approximate adjustments of procedures, it is also why everyday work in complex adaptive systems is safe [ 6 ]. To improve safety in complex adaptive systems, variability should be embraced, not erased [ 79 ]. This means that flexible and relationally based patient safety measures should be developed alongside the currently more standardised approaches. Protocols, procedures, and guidelines could for example form a starting point for reflections on how a certain practice might entail variability that go beyond these standardised measures and how the variability should be acted on.

The CAS perspective of clinical practice in suicide prevention also has implications for learning. To learn from variability, it is necessary to move from simple linear models (e.g., root cause analysis) to systemic models (e.g., resilience, CAS) focusing on why practices vary, succeed or fail at the clinical level, hospital management level and at the health system macro level [ 9 , 30 , 77 ].

Supporting resilient practices

This study describes resilient practices which outline complexity in the clinical work in suicidal inpatient care. Some generic lessons regarding how to approach patient safety and suicide prevention at the micro level of the system are drawn based on the RHC perspective.

In a CAS, it is impossible for the HCPs to anticipate all of the consequences of adjustments of procedures and trade-offs [ 80 , 81 ]. Feedback systems are needed to acquire knowledge of how to adapt and its outcomes [ 82 ]. This implies that, systems in mental healthcare need to collect feedback on everyday clinical practice to learn what fosters success under various conditions (Safety-II), not merely from retrospective views of suicide incidents [ 6 , 9 , 14 ]. Suicidal patients provide valuable feedback on what makes them feel safe or unsafe, identify conditions for successful treatment, and those that may cause adverse events. All of this corresponds to findings in other domains of healthcare [ 83 , 84 ]. Collecting patient feedback should be considered essential to support resilient practices for suicidal patients.

Furthermore, suicidal patients’ experiences should inform the development of patient safety measures. This study finding corresponds with the literature that identifies trust as fundamental for hospitalised patients’ feelings of safety [ 85 , 86 ]. The relational component of patient safety is the most vital aspect of care from the patients’ perspective, and HCPs can strengthen the sense of safety in those patients by respecting them as human beings, validating their feelings and ensuring that they know that people care about them. A sense of safety is also linked to a sense of control. HCPs may strengthen patients’ sense of control by addressing underlying issues and mental illnesses during hospitalisation and adapting suicide risk assessments and therapeutic approaches to suicidal behavior to meet each patient’s needs. An intervention which may support resilient practices is the collaborative assessment and management of suicide risk (CAMS) that involves the exploration of the suicidal patients’ individual drivers, warnings signs along with addressing the patient’s pain and suffering [ 87 , 88 ]. Furthermore, dialectical behavior therapy, which aims to improve patients’ emotional and practical coping skills is relevant [ 89 , 90 ].

This study implies that HCPs apply sensemaking strategies to improve their situational awareness of suicidal behavior. These strategies are enacted to gain a fuller meaning of the information they have obtained and a sense of what is going on in complex and ill-defined situations [ 75 , 76 , 91 ]. Since obtaining feedback from the healthcare team is essential in the creation of situational awareness [ 74 , 75 , 76 ], training in suicide risk detection can benefit from multidisciplinary training involving HCPs who regularly interact as a team to establish a shared vision, values and mental models [ 92 , 93 ]. HCPs need to be able to discuss their clinical judgement in everyday clinical practice with a team of colleagues [ 75 , 76 ]. In dialectical behavior therapy, and evidence-based treatment for borderline personality disorder with a specific focus on suicidal behavior, discussion of clinical assessment with colleagues is an integral part of the intervention [ 89 , 90 ]. Furthermore, the results indicate that opening a collaborative dialogue with the patient may also help HCPs’ sensemaking of suicidal behavior [ 87 ]. In this regard, sensemaking is concerned with supporting strategies that create a more comprehensible understanding that enables action [ 94 ]. Future studies are needed to develop complex interventions to improve HCPs’ shared situational awareness, non-verbal communication and relational skills in the patient contact, and may include the development of simulation training interventions for suicide risk assessment [ 95 ].

Following the literature, this study highlights the importance of having experienced HCPs [ 96 ], who are fully therapeutically engaged with the patient [ 97 , 98 ] who balance the exertion of control and the building of the therapeutic relationship during observation [ 99 ]. Observation of patients at suicide risk is a resilient practice that entails watchfulness and sensitivity to cues of a patient’s mental state along with engaging with the patient and establish bonds of trust. The findings are in accordance with research depicting prevention of suicides in constant observation as intertwined with forming connections and regaining hope [ 97 , 100 , 101 ]. The finding supports that observation demands resilient strategies from the individual HCPs and required adaptations and the balancing of multiple goals in care [ 28 , 30 , 77 , 102 ].

Lastly, this study implies that resilient practice should not rely solely on HCPs’ capacity to adapt without formal support systems. Without reliable sources of trust, the system is brittle. HCPs’ adaptive capacities may be overstretched and threaten the adaptive capacity of the system [ 103 , 104 , 105 ]. The findings also follow the literature finding that HCPs may distance themselves from suicidal patients’ emotions to protect themselves from emotional discomfort which may erode patients’ trust in their HCPs [ 106 , 107 , 108 ]. HCPs need to know they are supported, and thus they favour formal arenas for collegial trust, support [ 65 , 109 ], supervision and training to ensure they can keep working with suicidal patients [ 66 , 97 ]. Support systems are currently not considered a vital part of clinical guidelines for inpatient suicide prevention [ 10 ]. However, to support resilient practice, HCPs’ capacity to handle daily stress needs to be nurtured after incidents and on a daily basis. Clinical guidelines and patient safety policies related to inpatient suicide prevention need to include psychosocial support system and clinical supervision of HCPs.

Strengths and limitations

The ability to judge the quality of qualitative research rests on four characteristics: credibility, dependability, confirmability and transferability [ 110 ]. Triangulation of data sources (patients and professional groups), methods (focus groups, individual interviews and systematic review of literature) and the use of several researchers enhance the credibility of this synthesis: the confidence in the accuracy of the data and ensures that the research investigates what it intended to investigate. Credibility was strengthened by including a sample with sufficient information power [ 111 ], that covered significant variations and had relevant experiences with the phenomenon under study [ 112 ]. A sample size of 18 participants was considered adequate to ensure such information power when studying a heterogenic group of patients with suicidal behaviour [ 111 ]. A sample size of 18 and 25 HCPs was considered adequate to ensure variability across care settings (locked/open wards), diverse specialities (psychologists, nurses, medical doctors), gender, experience, expertise and patient diagnosis [ 111 ].

Dependability is strengthened in this synthesis by the provision of clear, detailed descriptions of all procedures and methods in the first author’s PhD thesis [ 45 ], the original studies [ 41 , 42 , 43 ], and by providing transparency through the published protocol [ 44 ], This allows for appraisal without the need to arrive at the same results [ 113 ].

Confirmability is the degree of neutrality and researcher bias [ 110 ]. Confirmability was strengthened through the sharing of the researchers’ backgrounds, preconceptions and pre-understandings to interpret the data [ 114 ]. This study adopted an inductive approach to analysis and curiosity about the experienced reality to describe resilient practices in this context, which reduces researcher bias through approaching data with sensitivity and openness [ 53 ].

Transferability is the extent to which the findings can be transferred to other settings, context or groups [ 113 ]. Qualitative data produce culturally situated knowledge which cannot be generalised to all inpatient practice settings [ 61 ]. The resilient practices described here are part of the processes of clinical practice, not linked to specific outcome measures (e.g., suicidal behaviour, symptoms). We therefore cannot draw conclusions on the effect of such practices related to suicidal behaviour and they should not replace current evidence-based system approaches to suicide prevention (e.g., [ 11 , 12 , 13 , 22 , 115 , 116 , 117 , 118 , 119 ]) However, the findings of this study can be conceptualised at a theoretical level and used to arrive at a deeper insight into the ontology of safety for suicidal patients [ 120 ]. This study focused on hospitalised patients who survived a suicidal crisis and resilient practices in mental health wards, as experienced by these patients and their HCPs. As such, the study conclusions do not pertain to patients dying from suicide or to patients who were not admitted to hospital wards during their suicidal crisis.

Resilient practices for patients hospitalised with suicidal behaviour are experienced by those patients and their HCPs using three practice types: interactions capturing non-verbal cues, protection through dignity and watchfulness, and personalised approaches to alleviate emotional pressure. All of these practice types are grounded in relationships of trust.

These practices inform the conceptual development of resilience in inpatient suicide prevention. The prevention of inpatient suicide is characterised by complexity related to changing, interrelated and variable patient needs in clinical practice and to the unpredictability of suicidal threats. Thus, inpatient suicide prevention demands adaptations and high levels of sensitivity towards the patient. To improve patient safety in this context, variability in clinical practice must be embraced. It is important to acknowledge the uncertainty in clinical decision-making regarding suicide risk and to avoid concluding that HCPs have performed an unsuccessful suicide risk assessment as the root cause of patient suicides. It is not possible to eliminate all uncertainty of suicide risk at the individual patient level. Nevertheless, it is possible to reduce emotional demands placed on HCPs by acknowledging the complexity and challenges involved in clinical decision-making regarding suicide.

Strategies should strengthen feedback systems that foster communication between HCPs and between HCPs and their patients, and reinforce systems such as clinical supervision that ensure support for HCPs. This synthesis was limited to the suicide inpatient care at the micro level of the healthcare system. Future studies should include the roles of family, carers, and ward management.

Health-related quality of life and clinical outcomes of adults with heart failure in nigeria: a review of current literature, ganiyu a amusa.

Background: Heart failure (HF) is a major public health problem due to its high prevalence, nature of morbidity and consequent socio-economic burden on individuals and societies. The established aims of the management are the prevention of disease progression and improving health-related quality of life (HRQoL). HF is a chronic illness known to have a negative impact on HRQoL with consequent adverse clinical outcomes. While there has been progress in reducing HF progression globally, not much has been achieved in improving RQoL, particularly in Nigeria and other low-resource countries. Methods : The available literature on the topic from PubMed, Medline, Google Scholar and other relevant internet sites were accessed, reviewed and inferences made. Conclusion : Heart failure has a significant negative impact on HRQoL with consequent poor clinical outcomes. Periodic assessment of HRQoL, HRQoL goal setting and adherence to guideline-directed medical therapy (GDMT) are recommended as standard care for individuals with HF in Nigeria and across the world

Metrics details

Therapeutic communication (TC) promotes effective patient care, emotional wellbeing, and improves patient outcomes. The purpose of this review was to synthesise evidence on barriers and outcomes of TC between nurses and patients in Africa and to inform future studies and systematic reviews.

Search for the records was done in four major databases including PubMed, Science Direct, PubMed CENTRAL, and JSTOR. Additional searches were done in Google Scholar and Google. Results and findings from published studies and grey literature were included. A total of 16 articles met the eligibility criteria and were included in the review. This scoping review followed the guidelines by Askey and O’Malley.

Barriers associated with TC were grouped under five main themes: sociodemographic factors, patient-related factors, nurse-related factors, environmental and health service-related. Age, and religious beliefs were the main sociodemographic factors that hindered TC while stress and inadequate knowledge and skills were identified among the nurse-related barriers to TC. Extreme weather conditions and mosquito infestation were environmental factors while lack of access to TC educational programmes on TC was a health service-related factor that interfered with TC. Both positive and negative outcomes of TC were also identified.

Continuous professional development on TC is necessary to improve nurses’ attitudes and update their skills to enable them to render culturally competent nursing care to patients.

Peer Review reports

Introduction

Therapeutic communication (TC) is fundamental to health service delivery [ 1 ]. TC includes the usage of communication and the development of a professional relationship between the nurse and the patient which may lead to positive patient outcomes that promote healing and recovery [ 2 ]. Therapeutic communication has evolved significantly within the nursing profession, reflecting an increasing understanding of its importance in patient care [ 1 ]. Initially rooted in basic communication principles, TC has matured to encompass a holistic approach that considers patients’ emotional needs, cultural backgrounds, and individual preferences [ 2 ]. Over time, nursing knowledge has recognized TC as not just a tool for relaying information but as a means to establish trust, empathy, and a supportive environment conducive to healing [ 3 ]. This evolution has been marked by a shift towards patient-centered care models, where nurses actively engage in dialogue, active listening, and empathetic responses to better address patient concerns and foster collaborative relationships [ 2 , 3 ]. As nursing continues to advance, TC remains a cornerstone, adapting to new technologies, diverse patient populations, and emerging healthcare challenges to ensure the delivery of compassionate and effective care.

Therapeutic communication, when practised consistently and effectively, has the potential to promote effective patient care, emotional wellbeing, and improve patient outcomes [ 3 ]. Bright and Reeves claimed that the art of TC entails prioritising patients’ needs and fostering a supportive environment in which care can be provided and accessed [ 4 ]. It also involves employing various interpersonal skills such as empathy, understanding and active listening which aims at establishing a meaningful connection with patients [ 5 ].

Navigating through the health system can be a daunting task for most patients and clients who may experience uncertainty and a sense of vulnerability [ 6 ]. In spite of this challenge, nurses are in a central position to create a supportive and welcoming atmosphere for these patients. A positive nurse-patient interaction is said to contribute to positive patient experiences and satisfaction, and better treatment outcomes [ 2 , 7 ]. Thus, nurses who spend longer times with patients are required to maintain a therapeutic relationship with clients and apply therapeutic communication to explore their physical and emotional well-being [ 8 ].

However, following decades of research on TC, there is a lack of review study that has mapped evidence on outcomes and barriers to effective TC [ 9 ]. This is typical of Africa where inadequacies are reported in the utilisation of TC which impacts negatively on the provision of nursing care [ 9 , 10 ].

It is argued that medical errors and patient injuries can be decreased with effective use of TC [ 4 ] which may also promote the psychosocial wellbeing of the client [ 11 ]. This review will fill this gap by synthesising the evidence on barriers and outcomes of TC between nurses and patients in Africa. The purpose is to inform future studies and systematic reviews. Additionally, this review aims to furnish substantiated evidence that has the potential to enrich the creation of policies and the integration of approaches geared towards enhancing therapeutic communication within nursing education and practice.

This scoping review is conducted using the guidelines by Arksey and O’Malley [ 12 ]. The steps include specifying the research question, identifying relevant literature, selecting studies, mapping out the data, summarising, synthesising, reporting of the results and including expert consultation. The reporting of the review follows PRISMA-ScR specifications [ 13 ].

Research questions which formed the basis for the review included: (1) What are the barriers of TC among nurses and patients in Africa (2)? What are the outcomes of TC between nurses and patients in Africa?

The inclusion and exclusion criteria for the review are presented in Table  1 .

Medical Subject Headings (MeSH) terms were used for the search in PubMed and subsequently modified for search in other databases (Science Direct, PubMed CENTRAL, and JSTOR). Table  2 shows the keywords and MeSH terms used for the strategic search in PubMed.

Additional searches were conducted in Google Scholar and Google for relevant materials. Records were exported into a Bibliographic Manager (Mendeley) and duplicates removed. Articles which were not relevant to the subject matter were also excluded. Reference check and institutional repository search also revealed some records which were screened by the team. Furthermore, reference lists of all eligible articles were carefully checked for potentially relevant full text articles. Complete articles that met the eligibility criteria for the review were finally saved in Mendeley for data extraction and charting.

Data extraction was conducted independently by two groups comprising six members each. To retrieve relevant studies, FN, JA, DFA, ROD, SAA, ITC, BKA, BOK, independently extracted the data for analysis. Details such as authors, the countries in Africa where the study was conducted, the purpose of the study, study design, population, sample size, study findings, and conclusions were extracted. Data were compared and inconsistencies that were detected from the charting reconciled by independent team members (MA, FN, JA, DFA, ROD, SAA, ITC, BOK). Thematic analysis and data synthesis were carried out using the method proposed by Braun and Clarke (2006) and the results presented according to the research questions. Authors acquainted themselves with the data that was extracted, and codes were assigned to the data to aid in the content's description. The gathered data was then examined by the authors for patterns and themes. The developed themes were then examined, described, and identified, and the outcomes presented. The review started on June 13 and ended with the last search on August 18, 2023.

Search results

A total of 7,755 records were retrieved. Sixteen records were retrieved from additional search in other databases (Google Scholar and Google). A total of 3,000 duplicates were removed. Following title and abstract screening, 37 full-text records remained after excluding 4734 records. The excluded records at this phase were not relevant to the topic under review. Checking the reference list of all the full-text records produced four records while consultation with a digital librarian also produced 2 records. A total of 16 records were finally included in this review. Reasons for excluding full-text records were provided. Details of search results and screening process are presented in Fig.  1 .

Study characteristics

Most reviewed studies used a qualitative design followed by cross-sectional designs with a few using mixed method (see Fig.  3 ). Majority of the reviewed studies were conducted in three countries in Africa including Ghana, Egypt and Ethiopia. See Fig. 2 for details. Also, most of the studies were conducted in 2019. Figures  3 and 4 present the years in which the studies were published and study designs respectively.

Study designs of reviewed studies

Findings were reported according to research questions (Barriers associated with TC and outcomes of TC).

Barriers associated with TC were grouped into sociodemographic factors, patient-related factors, nurse-related factors, environmental and health service-related. The outcomes were grouped under positive and negative outcomes of TC (Table  3 ).

Sociodemographic barriers

The studies reviewed indicated that the age of patients affected TC. Older and younger age of patients were observed to influence the effectiveness of TC between nurses and patients [ 14 , 15 , 16 , 18 ]. For instance, communicating with children requires the use of different words and strategies compared to adults since children cannot think in abstract terms. Emishaw also found that younger males preferred female nurses and vice versa [ 16 ].

Other studies reported that religious beliefs and tenets of both patients and nurses acted as barriers to effective TC in health facilities [ 14 , 15 , 16 ]. For instance, Muslim males preferred to be cared for by male nurses and vice versa [ 14 ]. In relation to gender, some studies found that therapeutic communication was effective when male patients were nursed by female patients and vice versa [ 15 , 16 ]. Cultural differences and practices between nurses and patients also affected effective TC [ 14 , 15 ]. For instance, beliefs that older dying patients had witchcraft affected TC between nurses and older patients [ 15 ]. Given that different cultures use language differently, language differences between nurses and patients were found to affect TC [ 16 , 17 , 19 ]. Therefore, ongoing validation is important in a therapeutic relationship to confirm interpretation of words. Another socio-demographic characteristic that impacted effective TC was education. Formal education on the part of patients was found to negatively affect the practice of TC in healthcare facilities [ 17 ]. Limited literacy of patients [ 23 ] was reported to affect TC. In addition, all-knowing attributes of some patients were more likely to impact negatively on TC between nurses and patients [ 14 , 15 ]. Furthermore, a review study found that marital status and being unmarried was a barrier to TC [ 16 ].

Nurse-related barriers

Evidence from the review showed that stress among nurses was a barrier to TC [ 20 , 21 ]. Also, a few years of work experience of the nurses negatively influenced TC [ 19 ]. Another study having more years of experience affected TC practice [ 22 ]. Inadequate knowledge and skills of TC [ 14 , 15 , 16 , 17 , 19 , 21 , 23 ] was found to be a barrier. The use of technical terms and jargons [ 17 , 19 ], and the inability of the nurses to explain technical terms [ 15 ] were also identified as barriers to TC. The review found that negative nurses’ attitudes and behaviours [ 15 , 20 , 26 ], lack of empathy [ 15 ], oppressive and judgemental attitudes [ 23 ] hindered TC between nurses and patients. Also, dissatisfaction and lack of love for the job [ 27 ], resistance and reluctance of the nurses to communicate with patients [ 19 ] impeded TC. The review found that the personality and/or mood of nurses hindered TC [ 23 ]. Furthermore, a study reported that the lack of professional decency and urgency of nurses was a barrier [ 15 ]. In addition, the unwillingness of nurses to work in poor working environments affected their communication with patients [ 28 ].

Patient related barriers

Evidence from this review suggested that, negative attitude of the patient towards the nurse was a barrier to TC [ 19 ]. In addition, the negative attitude of patients’ relatives hindered TC [ 15 , 26 ].

Patient’s dissatisfaction with nurses was reported by [ 14 , 15 ] as a hindrance to TC. Idleness on the part of the patient was identified as a barrier [ 14 ]. Also, patients’ misconceptions about nurses [ 14 ], stereotyping, lack of empathy, lack of respect from the nurses [ 15 ], and bad nursing care experience [ 23 ] were all found to affect TC between patients and nurses. The review also reported that pain [ 14 , 16 , 17 , 19 , 23 ], anxiety [ 15 , 19 ], and physical discomfort of the patient [ 19 ], deafness [ 26 ], patient condition [ 20 ] and patient mood swings [ 27 ] were all identified as barriers to TC. Lack of confidentiality was identified as a barrier to TC [ 19 ]. Additionally, patients’ family interference with care also affected TC [ 16 , 17 , 20 ]. Cubaka et al. reported that power imbalance weighing on the provider’s side was reported to affect TC [ 23 ].

Environment-related barriers

The reviewed studies reported that anxiety related to new environments [ 14 , 19 ] and long stay in health facilities [ 14 , 15 ] negatively impacted TC between nurses and patients. Also, extreme weather events such as very hot and cold wards affected TC [ 14 , 19 ]. Furthermore, noisy environments [ 14 , 15 , 16 ], distracting environments in relation to the light and fan [ 14 , 19 ], and the busy nature of the ward environment [ 16 , 19 ] also hinders the practice of TC. Also, mosquito infestation [ 14 , 15 ] and poor environment of the health facility [ 28 ] also impacted TC between nurses and patients.

Health facility related barriers

In relation to health facility factors, shortage of nursing staff [ 16 , 21 ] and high workload [ 14 , 17 , 19 , 20 , 21 , 22 , 23 , 28 ] were identified as hindrances to TC. Additionally, lack of access to therapeutic educational programmes [ 17 , 18 , 23 , 24 , 25 ], lack of medical facilities and drugs and lack of continuous TC opportunities [ 16 ] were reported as barriers to TC. Other impediments to TC identified from the reviewed studies were poor information on ward routines [ 21 ] and ineffective health insurance system [ 16 ].

Outcomes of therapeutic communication

The outcomes of TC between nurses and patients were grouped into positive and negative.

Positive outcomes

This review found that effective TC resulted in adherence of patients to treatment [ 21 , 27 ]. Furthermore, effective TC improved patients’ satisfaction with treatment protocol [ 25 ], communication with nurses [ 22 ], instructions and acceptance of guidance from nurses [ 27 ]. Another study reported effective TC fostered patients’ trust and improved recovery [ 18 ]. Successful TC also resulted in improvement in nurses’ skills in TC and the quality of nursing care [ 24 ] protection of patients’ rights [ 22 ].

Negative outcomes

A reviewed study showed that ineffective TC contributed to poor treatment compliance, medical errors, patient dissatisfaction with care and inefficient use of resources [ 20 ]. Also, negative TC reportedly resulted in non-supportive management [ 21 ].

The aim of the scoping review was to map evidence on the barriers impacting the practice of effective TC and its outcome. Findings from this review suggest that there are numerous obstacles to effective TC between nurses and in-patients in Africa. These hindrances were clients’ sociodemographic characteristics such as age and religious differences, limited experience of nurses, patients’ negative attitudes, bad experience of nursing care, and physical discomfort. Other obstacles to TC which were identified in the review related to the environment, climate and the working conditions. These included; hot and noisy ward environments, lack of access to therapeutic educational programmes, shortage of staff and ineffective health insurance system. From the review, it was found that one of the barriers that negatively impacts TC is the shortage of nurses who provide direct patient care to in-patients [ 16 , 21 ]. Nursing staff shortage could result in high workload for nurses who remain at work and therefore impede the ability to effectively communicate with patients. Consequently, this review also found high workload as an obstacle for effective TC between nurses and in-patients [ 14 , 15 , 16 , 17 , 20 , 22 , 23 ]. Furthermore, the review indicated that job-related stress among nurses served as a catalyst for ineffectiveness of TC as the emotional and social elements of communication are lost [ 29 ]. There is therefore the need for healthcare administrators and nurse managers to address these healthcare related factors that impede TC between nurses and patients. Kwame and Petrucka suggest a thorough examination of how this could be addressed [ 9 ].

Furthermore, this review found negative nursing attitudes such as lack of empathy hindered effective communication with admitted patients [ 15 ]. Sharafkhani et al. reported that nurses’ inability to express empathy and accept their own emotions produces gaps in therapeutic communication [ 30 ]. This is unfortunate as empathy is central to effective TC in healthcare settings. Consequently, this lack of empathy can result in increased patient anxiety, hostility and poor clinical outcomes [ 31 ].

Another barrier to TC found by this review was limited practical experience of nurses [ 19 ]. A similar finding. Also, ineffective TC by trained nurses may serve as a negative reinforcement for preservice nurses and thus, cause the problem to become institutionalised [ 32 ]. There is the need for supportive supervision by nurse managers and supervisors to ensure that TC is appropriately practised during nursing service delivery.

Cultural beliefs and practices such as the notion that older dying patients were witches and wizards caused reluctance among nurses in effectively communicating with older dying patients [ 14 , 15 ]. Most of these cultural barriers are compounded by the language differences that affect the effective communication of needs and expectations between nurses and patients [ 9 , 14 ].

The inadequate knowledge and skill of nurses with regard to TC can have a profound impact on the quality-of-care patients receive and their overall outcomes [ 8 ]. TC is an essential element in the nursing profession that entails proficient engagement and interaction with patients to foster recovery, confidence, and comprehension [ 2 ]. The absence of the requisite knowledge and skills in this domain among nurses may result in various limitations and consequences including fatal medical errors. Access to training opportunities in TC for nurses plays a pivotal role in the development and enhancement of therapeutic engagement with patients [ 15 , 19 ]. In turn, this can substantially ameliorate patient care and overall healthcare outcomes. The inability of nurses to explain technical terms and the use of medical jargon can equally have a significant impact on TC with patients [ 33 ]. Effective communication in healthcare requires clear and understandable dialogue between healthcare providers and patients. If nurses opt to employ intricate medical terminology that may not be comprehensible to patients, it may impede effective TC [ 14 ].

This review also identified positive outcomes of effective TC between and patients in Africa. Evidence suggested that successful TC leads to patient adherence [ 21 , 27 ] and satisfaction [ 25 ] to treatment protocol these is in agreement with Sherrill et al. who reported that effective TC enables healthcare workers to actively explain and listen to patients and their families making it easier for them to understand their specific needs, preferences and concerns. The results are also similar to that of Abrams et al. who reported that families of patients are very satisfied with the communication made by nurses [ 34 ]. In addition, effective TC also leads to patients understanding instructions and guidance from nurses [ 27 ]. Risna & Fauzia reported that nurse TC had a positive effect on the cooperative behaviour of patients with mental disorders [ 35 ]. Hence, the patient developed trust which eventually leads to improved outcome [ 18 ]. Finally, the reviewed studies found that effective communication is essential in preventing medication errors [ 2 , 8 , 36 ].

Limitations of the review

A significant majority of the included studies were qualitative and non-experimental. Included studies relied on self-report measures. This introduces biased responses from participants which may affect the generalisation of their findings. This situation may affect the generalisation of findings of this review.

Furthermore, the literature search was restricted to peer-reviewed articles and papers published in English. This situation may have affected the number of included studies and the depth of information presented in this review. Although the study focused on Africa, the majority of the papers were conducted in sub-Saharan Africa (SSA). This may be another limitation to generalising the findings to cover the entire African continent.

There could be papers unpublished on TC in languages other than English which may help understand TC’s importance and barriers in creating a safe and healthy work environment for healthcare delivery. However, this review focused primarily on papers published in English. This may reduce the number of included studies conducted on the subject matter in Africa.

Though there were limitations to the study findings, the review article is still relevant to nurses -patients relationship regarding TC.

Recommendations for future research

Reviewed papers on TC mainly conducted in Africa were included in this study. Most of these papers were conducted using a qualitative approach with much attention on sub-Saharan Africa. Quantitative designs may be needed to understand the concept of TC in nursing care.

Additionally, present literature on the subject matter focuses on nurses and patients. Hence, studies that seek to explore views of physicians, surgeons, clinical psychologists, pharmacists, laboratory technicians and other auxiliary staff in healthcare facilities are needed.

Moreover, the direct impact of TC on nursing care may need further exploration. More studies would also be required to explore the strengths and weaknesses of TC in health care delivery in Africa. Finally, understanding TC through the experiences of other health workers in the health facilities will be of significant benefit for patient care.

Implications for nursing practice, education and policy

The barriers for effective TC between nurses and patients in health care settings are numerous and require a comprehensive strategy to address them. Nurses who lack skills to practise TC might struggle to engage the patients at an emotional level. Hence, it leads to lower patients’ satisfaction levels. Also, TC must be integrated in all aspects of the nursing curricula to enhance nurses’ ability to effectively communicate with patients, families and healthcare teams. Policies to institutionalise supportive supervision on nurses practice of TC while interacting with patients should be established and implemented.

Cultural differences also hinder TC and affected nurses’ willingness to provide care to older dying patients. This means that geriatric patients may suffer neglect in health facilities while on admission. This may result in missed opportunities to provide comfort to dying patients, exacerbate patient anxiety and negatively impact patient care experience. Strategies to incorporate cultural competency and reflective practice in nursing practice should also be enforced.

Furthermore, shortage of nurses providing direct patient care results in increased workload. This could invariably cause stress among the nurses and affect the practice of effective TC negatively. When this is not resolved, it has the potential to impact preservice nurses who see these nurses as role models and mentors and serve as an avenue for negative learning. Health service managers must ensure the appraisal of nursing tasks and responsibilities and recruit more nurses to enhance opportunities for the implementation of effective TC.

Lack of access to educational programmes on TC may result in ineffective practice of TC such as using jargon and technical terms while communicating with patients. This could result in failure to effectively educate patients and families, and fester misunderstanding, anxiety and confusion. Nurse managers and health services administrators must invest in continuous professional development for nurses providing direct patient care to enhance their knowledge and skills.

In conclusion, this comprehensive review illuminates the multifaceted nature of therapeutic communication (TC) within nursing practice and its pivotal role in patient care outcomes across diverse healthcare settings in Africa. The analysis underscores a myriad of barriers spanning sociodemographic, nurse-related, patient-related, environment-related, and health facility-related domains, all of which significantly impede the effective exchange of information, empathy, and support between nurses and patients. Notably, the shortage of nursing staff, high workload, and limited access to educational programs emerge as critical impediments to nurturing meaningful therapeutic relationships. Moreover, the review underscores the nuanced interplay of cultural beliefs, patient attitudes, and environmental factors that shape the landscape of TC, underscoring the imperative for culturally sensitive and patient-centered approaches in nursing care delivery. The findings also highlight the imperative for robust policies, comprehensive nursing education curricula, and supportive supervision mechanisms to foster a conducive environment for effective TC practices. Moving forward, there is a compelling need for future research endeavors to delve deeper into the quantitative dimensions of TC, explore diverse healthcare stakeholders’ perspectives, and elucidate the direct impact of TC on patient outcomes. Ultimately, by addressing the identified barriers and embracing a holistic approach to TC, nursing practice, education, and policy can collectively pave the way for enhanced patient satisfaction, improved treatment adherence, and optimized healthcare delivery across the African continent.
