How to Write a Thematic Literature Review

Unlike literature reviews that focus on individual studies, thematic literature reviews allow scholars to organize and study research on a topic by identifying recurring themes or concepts. This approach not only ensures a more structured and nuanced understanding of a subject but also helps researchers identify gaps in existing knowledge. Put simply, thematic literature reviews are like piecing together parts of a puzzle to get a clearer idea of the larger picture and find questions that still need to be answered.  

Key steps for conducting a thematic literature review 

While putting together a well-structured thematic literature review may seem challenging, it is not necessarily so. Here are some key steps that will make the process easier: 

1. Define and establish the research question: The first step is to define and clearly state the research question. An unambiguous and relevant research question will help you narrow down the scope of your review and enable you to identify key themes or concepts that need to be studied. For example, instead of asking, “How does excessive use of social media affect behaviour?” it may be more effective to say, “What is the impact of excessive social media consumption on cognitive behaviour among adolescents?” 
2. Undertake a detailed literature search: Sifting through the vast amounts of information available both online and in print can prove tedious and frustrating. That is why using academic databases such as Web of Science, Google Scholar, and JSTOR is a good idea. Include information from other sources, like conference papers, to get a better understanding of the topic of your study. A pro tip is to record and track your search strategies and the keywords used to find relevant studies. This will prove helpful if you want to retrace your steps at a later stage.  
3. Check sources for credibility: It is important to assess the relevance and credibility of the sources you use in your thematic literature review. Check author credentials, date of publication, and the methodology used to ensure that the sources are of a high quality. 
4. Evaluate and organize sources based on specific themes: Grouping related studies thematically based on different concepts or ideas and using a chronological or comparative approach will help organize literature effectively. Taking forward the previous example, if your research question were about the impact of excessive social media consumption on cognitive behavior among adolescents, it would be a good idea to group studies into themes such as ‘Addiction and Dependency,’ ‘Psychological Effects,’ and ‘Cognitive Therapy.’ 
5. Identify gaps or potential areas for future study: Assess themes and ideas that have yet to be explored, identify any limitations in theory or methods, and consider how these can be studied further to develop potential trends. 

What does an impactful thematic literature review include?

Thematic literature reviews start with an introduction, discuss the key points in the body, and wrap up with a conclusion. Let’s look at each of these sections a little more closely –  

• Introduction: This section must provide a concise outline of the topic of your research and establish the significance of your research question. Spend time evaluating available literature and assessing key themes from different sources as they can help shape your review. 
• Body: This section is where you discuss key findings, evaluate methods, and discuss concepts gathered from different sources. Instead of merely summarizing sources, see how the topic of your research has evolved over time, focus on trends, discuss possible discrepancies or conflicts in ideas, and highlight any potential for future studies. Use paragraphs, headings, sub-headings, and appropriate transitional phrases to connect ideas and maintain an engaging narrative. 
• Conclusion: End your thematic literature review by summarizing the main points in a way that aligns with your research question. Ensure that this section is not a mere summation of the review but an analysis of key thematic findings that offer valuable insights.  
• Citing Sources: Listing citations accurately not only gives credit to the original authors but also lends credibility to your work. Use in-text citations with a comprehensive reference list at the end of your document, and ensure that you follow a consistent style when formatting the citations.

Mistakes to watch for when writing a thematic review

Writing a thematic literature review can be challenging, and it is not uncommon to find early-career researchers struggling with the task. Here are some tips that will help you avoid potential pitfalls –  

1. Getting distracted: Given the many different concepts and theories discussed during thematic literature reviews, it is easy to get distracted. To avoid this, keep focused on your research question. 
2. Narrow literature searches: Ensure that you conduct an in-depth review of available literature so that your study is well-rounded and complete. 
3. Neglecting recent studies: Ensure that you find and include the most current research on your topic. Outdated studies can undermine the relevance of your review. 
4. Failing to verify sources: Given the amount of misinformation today, confirming the provenance of your source is critical for ensuring your credibility as a scholar. 
5. Summarizing facts: Critically analyze and study information drawn from various sources. Discuss strengths and weaknesses, see how ideas and themes connect, and draw relevant inferences. 
6. Being unorganized: Recording and citing sources, following standard style guides, and following structured formats with clear thematic groupings enhances readability and comprehension. 
7. Using complicated language: Avoid using heavy technical terms, unnecessary jargon, and complicated language, as these can leave readers confused. Keep your writing simple and clear. 
8. Inaccuracies in citations: Failing to mention sources or citing them incorrectly reflects on your capabilities as a scholar. Check in-text citations and references to ensure that they are correctly listed. 
9. Ignoring gaps in the literature: Evaluate sources and flag possible gaps in understanding to ensure that your literature review is effective and complete. 
10. Failing to proofread and edit: Edit for clarity and coherence before finalizing your review. Grammatical errors and mistakes in language or formatting make work look unprofessional. 

Following the key steps and tips outlined above will help you create a coherent and engaging review that highlights relevant concepts, identifies gaps in the literature, and provides a solid foundation for future research.
