Qualitative research deals with non-numerical information, and thematic analysis is one of the approaches for such studies. Thematic analysis in qualitative research aims to identify, analyze, and interpret qualitative data patterns. In this type of analysis, a researcher carefully studies the data to identify core “themes,” which might be recurrently appearing ideas, theories, or patterns.
Thematic analysis is particularly useful for highlighting similarities and differences and for generating insights about a dataset. This method is used across various disciplines, including psychology, sociology, and education, and can offer in-depth insights and even contribute to theory development. As thematic analysis examples, one could consider the in-depth analyses of a collection of texts, such as field notes, interview transcripts, or survey responses, to find common themes. These themes could be repeated ideas, topics, or expressions.
What is Thematic Analysis?
Definition: A thematic analysis is a qualitative research method used to identify, analyze, and interpret patterns or themes within data. It extracts meaning from data by sorting, categorizing, and interpreting recurring themes. Qualitative thematic analysis is widely used in psychology, sociology, anthropology, and other social sciences.
When to Use Thematic Analysis?
Thematic analysis in research may be applied when gathering insights into people’s opinions, experiences, values, etc., from a set of qualitative data, e.g., survey responses, interview transcripts, or focus group discussions. It is particularly useful when the researcher aims to provide a detailed yet complex account of the data, going beyond mere description.
Such an analysis might answer questions such as “what are the views of millennials regarding dating apps?” or “how do Indigenous people perceive climate change?” To answer such questions, a researcher will collect data from the relevant population and analyze it.
Here are some more details as to when to use thematic analysis:
- Exploratory research: When investigating a new area or topic where little is known, thematic analysis can help identify key issues and patterns.
- Dealing with complex data: It may be used when dealing with data that contains nuanced or multifaceted information, such as interview transcripts or open-ended survey responses.
- Theory development: This analysis is suitable when in-depth insights are needed for developing a theory, i.e., in the inductive approach of research.
- Mixed methods research: Thematic analysis might form a component of a larger study that includes both qualitative and quantitative elements.
- Pattern identification: This approach can be used when the goal is to identify recurring themes across a dataset.
- Evolving research questions: This type of analysis is useful when flexibility is needed, e.g., when the research question may evolve during the study, as the approach allows for adjustment of focus.
Approaches to Thematic Analysis
Depending on your research question and theoretical framework, there are different approaches to qualitative thematic analysis.
- Deductive approach: If the framework offers pointers about the type of themes anticipated, you may use a deductive approach, where you approach the data with expected themes based on theory or existing knowledge.
Example: Studying employee perceptions of workplace culture (existing theory: Schein’s organizational culture model).
- Inductive approach: Instead, if you are aiming to generate your own framework based on what you find, you will use the inductive approach, wherein the data dictates your themes.
Example: Understanding employee experiences in a remote work environment (inductive themes: work–life balance, communication, productivity, technological challenges).
Another way to classify thematic analysis approaches is analyzing the content of the data stated as is (semantic approach) or reading into the subtext to tease out the deeper meaning of the statements (latent approach). Let’s differentiate the two by the following thematic analysis examples for “patient experiences in healthcare”:
- Semantic themes (analysis of direct statements on the following):
Wait times, staff behavior, cleanliness, treatment satisfaction
- Latent themes (analysis of underlying subtle meanings of feedback on the following):
Trust in the healthcare system, power dynamics, vulnerability, expectations of care.
How to Do Thematic Analysis (Step by Step)
Thematic analysis in research broadly involves six steps (see Figure 1).
- Get acquainted with the data: View the data from diverse perspectives. Carefully read and re-read all the collected material.
- Generate preliminary codes: Choose key quotes and keywords, and then identify emerging patterns to develop meaningful codes.
- Search for themes: Find emerging themes, and then identify subthemes and sub-patterns.
- Review the themes: Connect different themes to arrive at a comprehensive analysis of the research outcomes. Each theme should be distinctly identified and linked to the codes.
- Define the themes: Crystallize and finalize the themes.
- Write the report: Formulate the findings and draft the analysis.
Advantages and Disadvantages of Thematic Analysis
Before deciding on a thematic analysis approach, consider the following advantages and disadvantages to make the right choice for your research.
Thematic Analysis Advantages
- Thematic analysis in qualitative research offers flexibility to researchers to apply multiple theories within various frameworks.
- It is useful for research questions that extend beyond individual experiences.
- It permits the inductive development of codes and themes from the data.
- It handles large datasets well.
- Theme interpretation is directly supported by the data.
Thematic Analysis Disadvantages
- Thematic analysis can overlook subtle data if researchers are not cautious.
- The flexibility can make it challenging for novice researchers to determine which aspects of the data to prioritize.
- The analysis has limited interpretive power if it is not grounded in a theoretical framework.
- Maintaining data continuity across individual accounts might be challenging owing to the emphasis on identifying themes across the entire data set.
Key Takeaways
Here’s a summary of the main points about thematic analysis as discussed in the previous sections:
- Thematic analysis in research is a qualitative research method used to identify, analyze, and interpret patterns or themes within data.
- Its purpose is to extract meaning from data by sorting, categorizing, and interpreting recurring themes.
- This method is used for exploratory research, theory development, pattern identification and as a qualitative component within a larger mixed methods study.
- Approaches to thematic analysis include deductive, inductive, semantic, and latent.

- Thematic analysis advantages are flexibility, broad scope, inductive development, and handling of large datasets.
- Thematic analysis disadvantages are the potential to miss nuanced information, challenges in determining data priorities, limited interpretive power, and data continuity issues.
- A researcher’s subjective experience plays a major role in making sense of the data.
Frequently Asked Questions
1. What are the steps involved in thematic analysis?
Thematic analysis steps include getting acquainted with the data; generating preliminary codes; searching for themes; reviewing, defining, and finalizing the themes; and drafting the write-up.
2. What types of data can be analyzed using thematic analysis?
Data used for such thematic analyses are qualitative data, e.g., data from interviews, focus group discussions, and surveys.
3. How do you ensure the reliability and validity of thematic analysis?
Ensuring the reliability and validity of a thematic analysis involves the following:
- Start with a clear and coherent research question, design, and framework
- Use appropriate software tools to manage, organize, and visualize your data more efficiently and effectively
- Define codes clearly
- Ensure all coders are well-trained and understand the codebook.
- Calculate inter-coder reliability statistics (e.g., Cohen’s kappa) to assess the level of agreement between coders.
- Ensure consistent application of codes
- Maintain a detailed trail of all coding decisions and changes
- Develop a thematic map to visualize the relationships between themes
- Reflect on your own biases and assumptions and address any influence on the research process.
4. How do you generate initial codes in thematic analysis?
Initial codes are generated by systematically working through the data and tagging segments that appear interesting or relevant. These codes are basic units of meaning and serve as the foundation for identifying themes.
5. What is a theme in thematic analysis?
A theme is a pattern that captures something significant or interesting about the data in relation to the research question. Themes are constructed by grouping several codes that share a common idea or concept.
5. What is the difference between inductive and deductive thematic analysis?
Inductive thematic analysis is exploratory, allowing themes to emerge from the data itself, whereas deductive thematic analysis is confirmatory, guided by existing theories or frameworks. The choice between the two depends on the research goals, existing knowledge, and the nature of the research question.
6. What are some challenges of thematic analysis?
Challenges include ensuring the analysis is thorough and systematic, avoiding researcher bias, and managing large volumes of data. It also requires careful consideration of how themes are defined and interpreted.
