How to Write a Thematic Literature Review: A Beginner’s Guide

Literature reviews provide a comprehensive understanding of existing knowledge in a particular field, offer insights into gaps and trends, and ultimately lay the foundation for innovative research. However, when tackling complex topics spanning multiple issues, the conventional approach of a standard literature review might not suffice. Many researchers present a literature review without giving any thought to its organization or structure, but this is where a thematic literature review comes into play. In this article, we will explore the significance of thematic reviews, delve into how and when to undertake them, and offer invaluable guidance on structuring and crafting a compelling thematic literature review.

What is a thematic literature review?

A thematic literature review, also known as a thematic review, involves organizing and synthesizing the existing literature based on recurring themes or topics rather than a chronological or methodological sequence. Typically, when a student or researcher works intensively on their research there are many sub-domains or associated spheres of knowledge that one encounters. While these may not have a direct bearing on the main idea being explored, they provide a much-needed background or context to the discussion. This is where a thematic literature review is useful when dealing with complex research questions that involve multiple facets, as it allows for a more in-depth exploration of specific themes within the broader context.

When to opt for thematic literature review?

It is common practice for early career researchers and students to collate all the literature reviews they have undertaken under one single broad umbrella. However, when working on a literature review that involves multiple themes, lack of organization and structure can slow you down and create confusion. Deciding to embark on a thematic literature review is a strategic choice that should align with your research objectives. Here are some scenarios where opting for a thematic review is advantageous:

• Broad Research Questions: When your research question spans across various dimensions and cannot be adequately addressed through a traditional literature review.
• Interdisciplinary Research: In cases where your research draws from multiple disciplines, a thematic review helps in synthesizing diverse literature cohesively.
• Emerging Research Areas: When exploring emerging fields or topics with limited existing literature, a thematic review can provide valuable insights by focusing on available themes.
• Complex Issues: Thematic reviews are ideal for dissecting complex issues with multiple contributing factors or dimensions.

Advantages of a Thematic Literature Review

With better comprehension and broad insights, thematic literature reviews can help in identifying possible research gaps across themes. A thematic literature review has several advantages over a general or broad-based approach, especially for those working on multiple related themes.

• It provides a comprehensive understanding of specific themes within a broader context, allowing for a deep exploration of relevant literature.
• Thematic reviews offer a structured approach to organizing and synthesizing diverse sources, making it easier to identify trends, patterns, and gaps.
• Researchers can focus on key themes, enabling a more detailed analysis of specific aspects of the research question.
• Thematic reviews facilitate the integration of literature from various disciplines, offering a holistic view of the topic.
• Researchers can provide targeted recommendations or insights related to specific themes, aiding in the formulation of research hypotheses.

Now that we know the benefits of a thematic literature review, what is the best way to arrange reviewed literature in a thematic format?

How to write a thematic literature review

To effectively structure and write a thematic literature review, follow these key steps:

• Define Your Research Question: Clearly define the overarching research question or topic you aim to explore thematically. When writing a thematic literature review, go through different literature review sections of published research work and understand the subtle nuances associated with this approach.
• Identify Themes: Analyze the literature to identify recurring themes or topics relevant to your research question. Categorize the bibliography by dividing them into relevant clusters or units, each dealing with a specific issue. For example, you can divide a topic based on a theoretical approach, methodology, discipline or by epistemology. A theoretical review of related literature for example, may also look to break down geography or issues pertaining to a single country into its different parts or along rural and urban divides.
• Organize the Literature: Group the literature into thematic clusters based on the identified themes. Each cluster represents a different aspect of your research question. It is up to you to define the different narratives of thematic literature reviews depending on the project being undertaken; there is no one formal way of doing this. You can weigh how specific areas stack up against others in terms of existing literature or studies and how many more aspects may need to be added or further looked into.
• Review and Synthesize: Within each thematic cluster, review and synthesize the relevant literature, highlighting key findings and insights. It is recommended to identify any theme-related strengths or weaknesses using an analytical lens.
• Integrate Themes: Analyze how the themes interact with each other, draw linkages between earlier studies and see how they contribute to your own research. A thematic literature review presents readers with a comprehensive overview of the literature available on and around the research topic.
• Provide a Framework: Develop a framework or conceptual model that illustrates the relationships between the themes. Present the most relevant part of the thematic review toward the end and study it in greater detail as it reflects the literature most relevant and directly related to the main research topic.
• Conclusion: Conclude your thematic literature review by summarizing the key findings and their implications for your research question. Be sure to highlight any gaps or areas requiring further investigation in this section.
• Cite and Reference: It is important to remember that a thematic review of literature for a PhD thesis or research paper lends greater credibility to the student or researcher. So ensure that you properly cite and reference all sources according to your chosen citation style.
• Edit and Proofread: Take some time to review your work, ensure proper structure and flow and eliminate any language, grammar, or spelling errors that could deviate reader attention. This will help you deliver a well-structured and elegantly written thematic literature review.

Thematic literature review example

In essence, a thematic literature review allows researchers to dissect complex topics into smaller manageable themes, providing a more focused and structured approach to literature synthesis. This method empowers researchers to gain deeper insights, identify gaps, and generate new knowledge within the context of their research.

To illustrate the process mentioned above, let’s consider an example of a thematic literature review in the context of sustainable development. Imagine the overarching research question is: “What are the key factors influencing sustainable urban planning?” Potential themes could include environmental sustainability, social equity, economic viability, and governance. Each theme would have a dedicated section in the review, summarizing relevant literature and discussing how these factors intersect and impact sustainable urban planning. Close with a strong conclusion that highlights research gaps or areas of investigation. Finally, review and refine the thematic literature review, adding citations and references as required.

In conclusion, when tackling multifaceted research questions, a thematic literature review proves to be an indispensable tool for researchers and students alike. By adopting this approach, scholars can navigate the intricate web of existing literature, unearth meaningful patterns, and contribute to the advancement of knowledge in their respective fields. We hope the information in this article helps you create thematic reviews that illuminate your path to new discoveries and innovative insights.

Thematic Analysis Literature Review

A thematic literature review serves as a critical tool for synthesizing research findings within a specific subject area. By categorizing existing literature into themes, this method offers a structured approach to identify and analyze patterns and trends across studies. The primary goal is to provide a clear and concise overview that aids scholars and practitioners in understanding the key discussions and developments within a field. Unlike traditional literature reviews , which may adopt a chronological approach or focus on individual studies, a thematic literature review emphasizes the aggregation of findings through key themes and thematic connections. This introduction sets the stage for a detailed examination of what constitutes a thematic literature review, its benefits, and guidance on effectively structuring and writing one.

A thematic literature review methodically organizes and examines a body of literature by identifying, analyzing, and reporting themes found within texts such as journal articles, conference proceedings, dissertations, and other forms of academic writing. While a particular journal article may offer some specific insight, a synthesis of knowledge through a literature review can provide a comprehensive overview of theories across relevant sources in a particular field.

Unlike other review types that might organize literature chronologically or by methodology , a thematic review focuses on recurring themes or patterns across a collection of works. This approach enables researchers to draw together previous research to synthesize findings from different research contexts and methodologies, highlighting the overarching trends and insights within a field.

At its core, a thematic approach to a literature review research project involves several key steps. Initially, it requires the comprehensive collection of relevant literature that aligns with the review's research question or objectives. Following this, the process entails a meticulous analysis of the texts to identify common themes that emerge across the studies. These themes are not pre-defined but are discovered through a careful reading and synthesis of the literature.

The thematic analysis process is iterative, often involving the refinement of themes as the review progresses. It allows for the integration of a broad range of literature, facilitating a multidimensional understanding of the research topic. By organizing literature thematically, the review illuminates how various studies contribute to each theme, providing insights into the depth and breadth of research in the area.

A thematic literature review thus serves as a foundational element in research, offering a nuanced and comprehensive perspective on a topic. It not only aids in identifying gaps in the existing literature but also guides future research directions by underscoring areas that warrant further investigation. Ultimately, a thematic literature review empowers researchers to construct a coherent narrative that weaves together disparate studies into a unified analysis.

Conducting a literature review thematically provides a comprehensive and nuanced synthesis of research findings, distinguishing it from other types of literature reviews. Its structured approach not only facilitates a deeper understanding of the subject area but also enhances the clarity and relevance of the review. Here are three significant advantages of employing a thematic analysis in literature reviews.

Enhanced understanding of the research field

Thematic literature reviews allow for a detailed exploration of the research landscape, presenting themes that capture the essence of the subject area. By identifying and analyzing these themes, reviewers can construct a narrative that reflects the complexity and multifaceted nature of the field.

This process aids in uncovering underlying patterns and relationships, offering a more profound and insightful examination of the literature. As a result, readers gain an enriched understanding of the key concepts, debates, and evolutionary trajectories within the research area.

Identification of research gaps and trends

One of the pivotal benefits of a thematic literature review is its ability to highlight gaps in the existing body of research. By systematically organizing the literature into themes, reviewers can pinpoint areas that are under-explored or warrant further investigation.

Additionally, this method can reveal emerging trends and shifts in research focus, guiding scholars toward promising areas for future study. The thematic structure thus serves as a roadmap, directing researchers toward uncharted territories and new research questions .

Facilitates comparative analysis and integration of findings

A thematic literature review excels in synthesizing findings from diverse studies, enabling a coherent and integrated overview. By concentrating on themes rather than individual studies, the review can draw comparisons and contrasts across different research contexts and methodologies . This comparative analysis enriches the review, offering a panoramic view of the field that acknowledges both consensus and divergence among researchers.

Moreover, the thematic framework supports the integration of findings, presenting a unified and comprehensive portrayal of the research area. Such integration is invaluable for scholars seeking to navigate the extensive body of literature and extract pertinent insights relevant to their own research questions or objectives.

The process of structuring and writing a thematic literature review is pivotal in presenting research in a clear, coherent, and impactful manner. This review type necessitates a methodical approach to not only unearth and categorize key themes but also to articulate them in a manner that is both accessible and informative to the reader. The following sections outline essential stages in the thematic analysis process for literature reviews , offering a structured pathway from initial planning to the final presentation of findings.

Identifying and categorizing themes

The initial phase in a thematic literature review is the identification of themes within the collected body of literature. This involves a detailed examination of texts to discern patterns, concepts, and ideas that recur across the research landscape. Effective identification hinges on a thorough and nuanced reading of the literature, where the reviewer actively engages with the content to extract and note significant thematic elements. Once identified, these themes must be meticulously categorized, often requiring the reviewer to discern between overarching themes and more nuanced sub-themes, ensuring a logical and hierarchical organization of the review content.

Analyzing and synthesizing themes

After categorizing the themes, the next step involves a deeper analysis and synthesis of the identified themes. This stage is critical for understanding the relationships between themes and for interpreting the broader implications of the thematic findings. Analysis may reveal how themes evolve over time, differ across methodologies or contexts, or converge to highlight predominant trends in the research area. Synthesis involves integrating insights from various studies to construct a comprehensive narrative that encapsulates the thematic essence of the literature, offering new interpretations or revealing gaps in existing research.

Presenting and discussing findings

The final stage of the thematic literature review is the discussion of the thematic findings in a research paper or presentation. This entails not only a descriptive account of identified themes but also a critical examination of their significance within the research field. Each theme should be discussed in detail, elucidating its relevance, the extent of research support, and its implications for future studies. The review should culminate in a coherent and compelling narrative that not only summarizes the key thematic findings but also situates them within the broader research context, offering valuable insights and directions for future inquiry.

How to Do Thematic Analysis | Step-by-Step Guide & Examples

Published on September 6, 2019 by Jack Caulfield . Revised on June 22, 2023.

Thematic analysis is a method of analyzing qualitative data . It is usually applied to a set of texts, such as an interview or transcripts . The researcher closely examines the data to identify common themes – topics, ideas and patterns of meaning that come up repeatedly.

There are various approaches to conducting thematic analysis, but the most common form follows a six-step process: familiarization, coding, generating themes, reviewing themes, defining and naming themes, and writing up. Following this process can also help you avoid confirmation bias when formulating your analysis.

This process was originally developed for psychology research by Virginia Braun and Victoria Clarke . However, thematic analysis is a flexible method that can be adapted to many different kinds of research.

When to use thematic analysis, different approaches to thematic analysis, step 1: familiarization, step 2: coding, step 3: generating themes, step 4: reviewing themes, step 5: defining and naming themes, step 6: writing up, other interesting articles.

Thematic analysis is a good approach to research where you’re trying to find out something about people’s views, opinions, knowledge, experiences or values from a set of qualitative data – for example, interview transcripts , social media profiles, or survey responses .

Some types of research questions you might use thematic analysis to answer:

• How do patients perceive doctors in a hospital setting?
• What are young women’s experiences on dating sites?
• What are non-experts’ ideas and opinions about climate change?
• How is gender constructed in high school history teaching?

To answer any of these questions, you would collect data from a group of relevant participants and then analyze it. Thematic analysis allows you a lot of flexibility in interpreting the data, and allows you to approach large data sets more easily by sorting them into broad themes.

However, it also involves the risk of missing nuances in the data. Thematic analysis is often quite subjective and relies on the researcher’s judgement, so you have to reflect carefully on your own choices and interpretations.

Pay close attention to the data to ensure that you’re not picking up on things that are not there – or obscuring things that are.

Professional editors proofread and edit your paper by focusing on:

• Vague sentences

Once you’ve decided to use thematic analysis, there are different approaches to consider.

There’s the distinction between inductive and deductive approaches:

• An inductive approach involves allowing the data to determine your themes.
• A deductive approach involves coming to the data with some preconceived themes you expect to find reflected there, based on theory or existing knowledge.

Ask yourself: Does my theoretical framework give me a strong idea of what kind of themes I expect to find in the data (deductive), or am I planning to develop my own framework based on what I find (inductive)?

There’s also the distinction between a semantic and a latent approach:

• A semantic approach involves analyzing the explicit content of the data.
• A latent approach involves reading into the subtext and assumptions underlying the data.

Ask yourself: Am I interested in people’s stated opinions (semantic) or in what their statements reveal about their assumptions and social context (latent)?

After you’ve decided thematic analysis is the right method for analyzing your data, and you’ve thought about the approach you’re going to take, you can follow the six steps developed by Braun and Clarke .

The first step is to get to know our data. It’s important to get a thorough overview of all the data we collected before we start analyzing individual items.

This might involve transcribing audio , reading through the text and taking initial notes, and generally looking through the data to get familiar with it.

Next up, we need to code the data. Coding means highlighting sections of our text – usually phrases or sentences – and coming up with shorthand labels or “codes” to describe their content.

Let’s take a short example text. Say we’re researching perceptions of climate change among conservative voters aged 50 and up, and we have collected data through a series of interviews. An extract from one interview looks like this:

In this extract, we’ve highlighted various phrases in different colors corresponding to different codes. Each code describes the idea or feeling expressed in that part of the text.

At this stage, we want to be thorough: we go through the transcript of every interview and highlight everything that jumps out as relevant or potentially interesting. As well as highlighting all the phrases and sentences that match these codes, we can keep adding new codes as we go through the text.

After we’ve been through the text, we collate together all the data into groups identified by code. These codes allow us to gain a a condensed overview of the main points and common meanings that recur throughout the data.

Prevent plagiarism. Run a free check.

Next, we look over the codes we’ve created, identify patterns among them, and start coming up with themes.

Themes are generally broader than codes. Most of the time, you’ll combine several codes into a single theme. In our example, we might start combining codes into themes like this:

At this stage, we might decide that some of our codes are too vague or not relevant enough (for example, because they don’t appear very often in the data), so they can be discarded.

Other codes might become themes in their own right. In our example, we decided that the code “uncertainty” made sense as a theme, with some other codes incorporated into it.

Again, what we decide will vary according to what we’re trying to find out. We want to create potential themes that tell us something helpful about the data for our purposes.

Now we have to make sure that our themes are useful and accurate representations of the data. Here, we return to the data set and compare our themes against it. Are we missing anything? Are these themes really present in the data? What can we change to make our themes work better?

If we encounter problems with our themes, we might split them up, combine them, discard them or create new ones: whatever makes them more useful and accurate.

For example, we might decide upon looking through the data that “changing terminology” fits better under the “uncertainty” theme than under “distrust of experts,” since the data labelled with this code involves confusion, not necessarily distrust.

Now that you have a final list of themes, it’s time to name and define each of them.

Defining themes involves formulating exactly what we mean by each theme and figuring out how it helps us understand the data.

Naming themes involves coming up with a succinct and easily understandable name for each theme.

For example, we might look at “distrust of experts” and determine exactly who we mean by “experts” in this theme. We might decide that a better name for the theme is “distrust of authority” or “conspiracy thinking”.

Finally, we’ll write up our analysis of the data. Like all academic texts, writing up a thematic analysis requires an introduction to establish our research question, aims and approach.

We should also include a methodology section, describing how we collected the data (e.g. through semi-structured interviews or open-ended survey questions ) and explaining how we conducted the thematic analysis itself.

The results or findings section usually addresses each theme in turn. We describe how often the themes come up and what they mean, including examples from the data as evidence. Finally, our conclusion explains the main takeaways and shows how the analysis has answered our research question.

In our example, we might argue that conspiracy thinking about climate change is widespread among older conservative voters, point out the uncertainty with which many voters view the issue, and discuss the role of misinformation in respondents’ perceptions.

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.

• 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.

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.

You can use our free APA Reference Generator for quick, correct, consistent citations.

Prevent plagiarism, run a free check.

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 .

Thematic Literature Review: A Beginner’s Guide

A thematic literature review is a powerful tool for synthesizing and analyzing existing research within a specific thematic framework. It enables researchers to explore key themes, patterns, and trends across a body of literature, providing valuable insights and understanding in a particular field or topic. In this beginner’s guide, we’ll delve into the essential steps and strategies for crafting a compelling thematic literature review.

Understanding Thematic Literature Reviews:

A thematic literature review focuses on identifying, analyzing, and synthesizing common themes, concepts, or patterns within a body of literature related to a specific research topic or question. Unlike traditional narrative reviews, which provide a chronological overview of literature, thematic reviews organize and categorize information based on thematic connections and relationships.

Steps to Write a Thematic Literature Review:

Define Your Research Question and Objectives:

• Clearly define your research question or topic of interest that will guide the thematic review.
• Determine the specific objectives or goals of the review, such as identifying themes, exploring relationships, or evaluating gaps in knowledge.

Conduct a Comprehensive Literature Search:

• Use academic databases, journals, books, and other sources to gather relevant literature related to your research topic.
• Employ keyword searches, Boolean operators, and advanced search techniques to identify key studies and resources.

Select and Evaluate Relevant Literature:

• Evaluate the quality, relevance, and credibility of each source based on criteria such as authorship, methodology, research design, and publication date.
• Select literature that directly contributes to addressing your research question and thematic focus.

Organize Literature Based on Themes:

• Identify common themes, concepts, or patterns emerging from the selected literature.
• Create a thematic framework or coding scheme to categorize and organize literature based on thematic connections and relationships.

Synthesize and Analyze Themes:

• Analyze each theme or category in-depth, summarizing key findings, arguments, and perspectives from the literature.
• Identify similarities, differences, contradictions, and gaps within and across themes to develop a comprehensive understanding of the research landscape.

Write the Thematic Literature Review:

• Structure the review based on thematic categories or sections, clearly labelling and defining each theme.
• Provide a synthesis of findings, discussing the implications, significance, and contributions of each theme to the research topic.

Include Critical Reflection and Discussion:

• Critically reflect on the strengths, limitations, and methodological considerations of the reviewed literature.
• Engage in a thoughtful discussion of the implications, theoretical frameworks, and future research directions based on the thematic analysis.

Use Clear and Concise Writing Style:

• Write in a clear, concise, and organized manner, presenting information logically and cohesively.
• Use transitions, signposts, and citations to guide readers through the thematic review and connect ideas seamlessly.

Tips for Writing a Compelling Thematic Literature Review:

• Stay Focused: Maintain focus on the thematic analysis and avoid unnecessary tangents or deviations from the main themes.
• Engage Critically: Critically evaluate and analyze literature, offering insights, interpretations, and evaluations within each theme.
• Provide Evidence: Support your analysis and arguments with evidence, citations, and references from the reviewed literature.
• Be Objective: Maintain objectivity and impartiality in presenting and interpreting findings, avoiding bias or personal opinions.
• Revise and Edit: Revise and edit your thematic review for clarity, coherence, and accuracy, ensuring that it meets scholarly standards and expectations.

Conclusion:

Crafting a thematic literature review requires careful planning, thorough research, critical analysis, and effective synthesis of findings. By following the steps outlined in this beginner’s guide and incorporating tips for writing a compelling thematic review, researchers can create a valuable scholarly contribution that enhances understanding, identifies trends, and informs future research in their field of study. Remember to approach the thematic review process with curiosity, rigour, and attention to detail, striving to uncover meaningful insights and contribute to the advancement of knowledge within your research area.

Tips for creating a literature review template

Literary review templates are surveys of scholarly sources on a specific subject matter. It gives a general summary of information relevant to a certain research problem or question. Here are the steps to follow when creating a literary review.

• Gather, assess, and choose the appropriate literature Before researching for literature for a review, you must have a topic that’s narrowly-defined. If you were to write a review for some research work or dissertation, you have to gather information related to the research problem or question. Having to understand the state of knowledge of your subject is the first step in creating your outline for literature review. Composing a literature review outline example for stand-alone research shouldn’t be that difficult. You only have to a good focus, then come up with a question that directs your search. This should be an answerable question without the need to generate or collect new data. Start the process by making a list of relevant keywords for the research topic in question. Based on the list, whenever you discover useful articles, check your list of references to find other relevant articles. During this process, you can identify any significant publications which didn’t show up when you performed a keyword search through recurring citations. It’s impossible for you to read all the available sources about a single topic. The best thing to do first is to read the abstract and determine if the articles are of any use. You have to do some evaluations on which of the sources are of value and relevant to the question. Also, make sure to only choose credible sources. Make it a point to read major theories and landmark studies in the field of your research. Logically, your scope of work depends upon the discipline and topic you have chosen. Make it a habit of writing down notes while you’re reading. Later on, you can incorporate these notes in your literature review format. Also, consider keeping track of the sources you have cited to avoid any consequential plagiarism cases. Making an annotated bibliography is a good suggestion. Include here a written paragraph for the summary and the analysis for each cited source. This can also be very helpful in reminding you about what you have read.
• Look for themes and connections When you start organizing a literature review format, you should identify the relationships between all of the sources that you have read. Based on what you have read and the notes you have taken, look for: Patterns and trends: Are there approaches which become less or more popular as time goes by? Themes: Identifying concepts or questions that repeat constantly across the different literature. Conflicts, contradictions, and debates: At what points do the sources disagree or agree? Pivotal publications: Identify any influential studies or theories which affected the direction of the field. Gaps: Try looking for answers for the following questions – What’s missing from the literature? Did you find any weaknesses that you need to address? The answers to these questions can help organize the structure of the literary review. If applicable, you can include how your research contributes to the existing knowledge.
• Plan the structure of your literature review template You can organize the whole body of your literary review through various approaches but at this point, you should already have an idea of the strategy you want to use even before writing your review. Depending on how long your review will be, you can use the following strategies: Chronological This is the simplest strategy where you map out the development of your topic over a period of time. If you use this approach, you should avoid merely listing or summarizing your sources chronologically. Make it a point to analyze the patterns, key events, and turning points that have influenced the direction of the field. If possible, give your own ideas about why and how certain developments came to happen. Thematic If you’ve discovered, in the course of your research, some recurring themes, you may organize your literary review into subsections which address the different parts of your topic. Methodology When you’re drawing your sources from various fields or disciplines which use different methods for research, you may end up with different conclusions and results. Perform analysis and try to compare these results that emerged from the different approaches. Theoretical In many cases, a literary review becomes the basis for theoretical frameworks. You may use this to talk about various definitions, theories, and models of important concepts. You may even argue about the significance of a theoretical approach or you can combine different theoretical ideas to come up with your own framework for research.

Outlines For Literature Review

Compose the literature review

The literary review isn’t any different in form from any other kind of academic texts as it also has the basic parts. What you included in each would depend upon your objective for writing the literature review:

• Introduction This part should clearly define the purpose and focus of the review. Dissertation: If you wrote the review as a part of a thesis or dissertation, you must reiterate the research question or central problem. Provide a short summary of the context as well. Stand-Alone: When writing this type of review, provide a short background regarding the topic along with its significance. Talk about the scope you plan to review along with your objective.
• Body If you have a lengthy review, it’s best to divide this part into sub-sections then come up with a subheading for each of them.
• Conclusion State in the conclusion, a summary of the key findings you have derived from the literature and emphasize their significance. Dissertation: Demonstrate how your research can address gaps and how it can contribute to gaining new knowledge. You can also discuss how you have used existing theories and methods to build a framework for your research. Stand-Alone: Discuss the overall effects of the literature or make suggestions for future research based on those gaps you have identified in your review.

Strategies for composing your literature review template

Most people write literature review templates in the sciences although occasionally, some are in the Humanities. In many experiments and laboratory reports, literature reviews constitute a section of the document. At times, some people write the review as the paper itself. Here are some strategies that may prove helpful when tasked to write a literature review:

• Find your focus Although they can differ, a literary review is like a term paper as you would organize both around ideas, not the sources themselves. This means that writing a review is not merely about listing your sources and going into their details one at a time. You also have to consider the themes and issues that connect your sources together.
• Convey your message Literary reviews may not have the usual thesis statement but you still need to inform your readers what to expect. Writing a simple statement is enough to let your readers know what your main organizing principle is.
• Organize the information There are instances when you may need additional sections in your review which are necessary for the study but don’t fit into the body’s organizational strategy. This depends on which sections you want to include. Only put in those that are necessary. To help you out, here are some sections that you may want to include in your review: Current Situation: This refers to the information that’s necessary to easily understand the focus or topic of the review. History: The chronological progression of the field, the literature, or an idea that’s necessary to understand the literature review. Include this only if the body isn’t already arranged chronologically. Methods or Standards: What criteria did you use to choose the sources in your review or the manner in which you want to present the information. Questions for Further Research: Are there questions about your field of research the review had sparked? Based on the review, what steps can you take to advance your research?

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: 

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. 

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. 

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. 

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.

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:

Writing a Literature Review

Welcome to the Purdue OWL

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, 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 transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How to structure and write a Thematic Literature Review

By charlesworth author services.

• Charlesworth Author Services
• 02 July, 2022

In the previous article , you looked at how the literature review, wherever it is found, whether in the introduction or in a separate section, might be organised chronologically. Perhaps a more common way to organise the literature review is to group the literature as you see it – that is, to organise and discuss the literature by theme.

Advantages of doing a thematic literature review 

• Taking a thematic approach from an early point in your research allows you to see how much literature you have identified for each issue . You can then assess how much more you might need to read. 
• Identify which areas may suffer from a significant lack of existing literature/studies .
• Highlight outstanding gaps in the current body of work.
• Demonstrate the need or opportunities for extending previous research. 
• Taking this evaluative approach allows you more space to assert your own voice and authority , and to engage more intimately with the literature from the beginning. You’ll get to take a more active role in identifying the connections between existing studies and research on your topic.
• By building connections between themes to your research project, you’ll help your reader gain a better, broader overview of the relevant literature.

Deciding on a thematic literature review

One way to do decide going thematic with your literature review is to categorise your bibliography at an early stage into groups , each of which deals with a particular issue in a similar way.

• So, you might look at a topic by discipline, by epistemology, by theoretical approach or argument or by methodology.
• Alternatively, you might look at the topic by issue or by level (e.g. selecting literature that focuses on individuals at a local / institutional level, rather than national or international). 

Note : There are innumerable ways of viewing the literature from a thematic standpoint and there is no one correct method to write or structure a thematic literature review. It is more important to consider what approaches would be more useful to your research project and what would help you to best address your research questions / hypotheses .

Structuring and writing a thematic literature review

Here are some points to keep in mind when organising and writing your literature review thematically.

A. Beginning the review

Reviewing the literature thematically by groups offers you a flexible starting point. Where you begin can impact how you present the rest of the literature. 

B. Being evaluative

The thematic approach allows you to identify the strengths and weaknesses of a theme within your specific research. This means that it may be less descriptive than taking a more chronological approach, and would likely be more evaluative or analytical . 

C. Establishing your credentials

This review is an important element in establishing your academic credentials, especially at the PhD level. In journal articles , though, you need to keep it as concise as possible, and be selective in choosing the most relevant and appropriate literature to contextualise your specific research.

D. Ending the review

You will probably want to end with the literature closest to your research . The last part may need to go into greater detail if it covers the literature that is the most relevant to your own topic.

Thematic literature review: Example

Below is the first section to an article which clearly breaks up the first part of the literature review into three broad themes (structure, social construction and historical evolution), providing the most prominent names associated with each one. (Note the highlighted text.)

Over the last 20 years, a large number of studies on academic writing have been devoted to the research article, in particular, its structure, social construction and historical evolution. A number of these studies have concerned themselves with the overall organization of various parts of the research article , such as the introduction (e.g. Swales, 1981, Swales, 1990, Swales and Najjar, 1987), the results sections (Brett, 1994, Thompson, 1993), discussions (Hopkins & Dudley-Evans, 1988) and even the abstracts that accompany the research articles (Salager-Meyer, 1990, Salager-Meyer, 1992). Various lexico-grammatical features of the research article (RA) have also been explored, ranging from tense choice to citation practices. Beyond the textual structure of this genre, research has also focused on the historical development of the research article (Bazerman, 1988, Atkinson, 1993, Salager-Meyer, 1999, Vande Kopple, 1998) and the social construction of this genre (Myers, 1990).

The matrix method for literature reviews.

This handout is available for download in DOCX format and PDF format .

What is the Matrix Method, and why should I use it?

Using a review matrix enables you to quickly compare and contrast articles in order to determine the scope of research across time. A review matrix can help you more easily spot differences and similarities between journal articles about a research topic. While they may be helpful in any discipline, review matrices are especially helpful for health sciences literature reviews covering the complete scope of a research topic over time. This guide focuses on the review matrix step in the literature review process and offers tips on how to use it effectively.

Organize your sources

Once you complete your research, organize your source by date in order to make it easier to see changes in research over time.

Begin by creating the blank matrix. The matrices can be easily constructed using table-making software such as Microsoft Excel, Word or OneNote, Google Sheets, or Numbers. Every review matrix should have the same first three column headings: (1) authors, title, and journal, (2) publication year, and (3) purpose.

Be aware that it may be difficult to determine purpose from just a cursory review of the article. In some cases, it may be necessary to first read the paper fully to identify its purpose.

Choose your remaining column topics

Next, carefully read all your articles. Note any important issues you identify. The following broad categories provide some suggestions for determining your own subject headings:

Methodological

Methodology is often an important question. For example, if you are looking at tests of an Ebola vaccine beyond human subjects, it will be important to note what type of animal the test was carried out on, i.e. macaques or mice.

Content-specific

Consider noting what was actually studied. For example, when looking at the effectiveness of traditional Chinese medicine in the treatment of illnesses, it would be important to note what illness was being studied.

Geographical

It may be important to note where the research was completed. For example, if you want to compare the effects of the AIDS epidemic in different countries, you would use country as a column heading.

There are many ways to choose your column headings, and these are just a few suggestions. As you create your own matrix, choose column headings that support your research question and goals.

• Do not include column headings that are explicit in your research question. For example, if you are looking at drug use in adolescents, do not include a column heading for age of study participants. If the answer will be the same for every study, it's generally a bad choice for a column heading.
• Do not try to fully complete a review matrix before reading the articles. Reading the articles is an important way to discern the nuances between studies.

Introduction

Literature reviews offer a critical synthesis of empirical and theoretical literature to assess the strength of evidence, develop guidelines for practice and policymaking, and identify areas for future research. 1 It is often essential and usually the first task in any research endeavour, particularly in masters or doctoral level education. For effective data extraction and rigorous synthesis in reviews, the use of literature summary tables is of utmost importance. A literature summary table provides a synopsis of an included article. It succinctly presents its purpose, methods, findings and other relevant information pertinent to the review. The aim of developing these literature summary tables is to provide the reader with the information at one glance. Since there are multiple types of reviews (eg, systematic, integrative, scoping, critical and mixed methods) with distinct purposes and techniques, 2 there could be various approaches for developing literature summary tables making it a complex task specialty for the novice researchers or reviewers. Here, we offer five tips for authors of the review articles, relevant to all types of reviews, for creating useful and relevant literature summary tables. We also provide examples from our published reviews to illustrate how useful literature summary tables can be developed and what sort of information should be provided.

Tip 1: provide detailed information about frameworks and methods

The provision of information about conceptual and theoretical frameworks and methods is useful for several reasons. First, in quantitative (reviews synthesising the results of quantitative studies) and mixed reviews (reviews synthesising the results of both qualitative and quantitative studies to address a mixed review question), it allows the readers to assess the congruence of the core findings and methods with the adapted framework and tested assumptions. In qualitative reviews (reviews synthesising results of qualitative studies), this information is beneficial for readers to recognise the underlying philosophical and paradigmatic stance of the authors of the included articles. For example, imagine the authors of an article, included in a review, used phenomenological inquiry for their research. In that case, the review authors and the readers of the review need to know what kind of (transcendental or hermeneutic) philosophical stance guided the inquiry. Review authors should, therefore, include the philosophical stance in their literature summary for the particular article. Second, information about frameworks and methods enables review authors and readers to judge the quality of the research, which allows for discerning the strengths and limitations of the article. For example, if authors of an included article intended to develop a new scale and test its psychometric properties. To achieve this aim, they used a convenience sample of 150 participants and performed exploratory (EFA) and confirmatory factor analysis (CFA) on the same sample. Such an approach would indicate a flawed methodology because EFA and CFA should not be conducted on the same sample. The review authors must include this information in their summary table. Omitting this information from a summary could lead to the inclusion of a flawed article in the review, thereby jeopardising the review’s rigour.

Tip 2: include strengths and limitations for each article

Critical appraisal of individual articles included in a review is crucial for increasing the rigour of the review. Despite using various templates for critical appraisal, authors often do not provide detailed information about each reviewed article’s strengths and limitations. Merely noting the quality score based on standardised critical appraisal templates is not adequate because the readers should be able to identify the reasons for assigning a weak or moderate rating. Many recent critical appraisal checklists (eg, Mixed Methods Appraisal Tool) discourage review authors from assigning a quality score and recommend noting the main strengths and limitations of included studies. It is also vital that methodological and conceptual limitations and strengths of the articles included in the review are provided because not all review articles include empirical research papers. Rather some review synthesises the theoretical aspects of articles. Providing information about conceptual limitations is also important for readers to judge the quality of foundations of the research. For example, if you included a mixed-methods study in the review, reporting the methodological and conceptual limitations about ‘integration’ is critical for evaluating the study’s strength. Suppose the authors only collected qualitative and quantitative data and did not state the intent and timing of integration. In that case, the strength of the study is weak. Integration only occurred at the levels of data collection. However, integration may not have occurred at the analysis, interpretation and reporting levels.

Tip 3: write conceptual contribution of each reviewed article

While reading and evaluating review papers, we have observed that many review authors only provide core results of the article included in a review and do not explain the conceptual contribution offered by the included article. We refer to conceptual contribution as a description of how the article’s key results contribute towards the development of potential codes, themes or subthemes, or emerging patterns that are reported as the review findings. For example, the authors of a review article noted that one of the research articles included in their review demonstrated the usefulness of case studies and reflective logs as strategies for fostering compassion in nursing students. The conceptual contribution of this research article could be that experiential learning is one way to teach compassion to nursing students, as supported by case studies and reflective logs. This conceptual contribution of the article should be mentioned in the literature summary table. Delineating each reviewed article’s conceptual contribution is particularly beneficial in qualitative reviews, mixed-methods reviews, and critical reviews that often focus on developing models and describing or explaining various phenomena. Figure 2 offers an example of a literature summary table. 4

Tip 4: compose potential themes from each article during summary writing

While developing literature summary tables, many authors use themes or subthemes reported in the given articles as the key results of their own review. Such an approach prevents the review authors from understanding the article’s conceptual contribution, developing rigorous synthesis and drawing reasonable interpretations of results from an individual article. Ultimately, it affects the generation of novel review findings. For example, one of the articles about women’s healthcare-seeking behaviours in developing countries reported a theme ‘social-cultural determinants of health as precursors of delays’. Instead of using this theme as one of the review findings, the reviewers should read and interpret beyond the given description in an article, compare and contrast themes, findings from one article with findings and themes from another article to find similarities and differences and to understand and explain bigger picture for their readers. Therefore, while developing literature summary tables, think twice before using the predeveloped themes. Including your themes in the summary tables (see figure 1 ) demonstrates to the readers that a robust method of data extraction and synthesis has been followed.

Tip 5: create your personalised template for literature summaries

Often templates are available for data extraction and development of literature summary tables. The available templates may be in the form of a table, chart or a structured framework that extracts some essential information about every article. The commonly used information may include authors, purpose, methods, key results and quality scores. While extracting all relevant information is important, such templates should be tailored to meet the needs of the individuals’ review. For example, for a review about the effectiveness of healthcare interventions, a literature summary table must include information about the intervention, its type, content timing, duration, setting, effectiveness, negative consequences, and receivers and implementers’ experiences of its usage. Similarly, literature summary tables for articles included in a meta-synthesis must include information about the participants’ characteristics, research context and conceptual contribution of each reviewed article so as to help the reader make an informed decision about the usefulness or lack of usefulness of the individual article in the review and the whole review.

In conclusion, narrative or systematic reviews are almost always conducted as a part of any educational project (thesis or dissertation) or academic or clinical research. Literature reviews are the foundation of research on a given topic. Robust and high-quality reviews play an instrumental role in guiding research, practice and policymaking. However, the quality of reviews is also contingent on rigorous data extraction and synthesis, which require developing literature summaries. We have outlined five tips that could enhance the quality of the data extraction and synthesis process by developing useful literature summaries.
