This paper critically reviews the use of thematic analysis (TA) in qualitative research, comparing it with grounded theory (GTA) and hermeneutic analysis. It highlights the lack of clarity in TA's conceptualization, process, and validation. Thematic analysis is described as a comprehensive process that allows researchers to identify cross-references between data and evolving themes. It offers flexibility in both inductive and deductive approaches, making it suitable for analyzing data when the research aims to explore relationships between variables and compare different sets of evidence. Thematic analysis is appropriate when data interpretation is needed, when both inductive and deductive approaches are applicable, when analyzing data from different phases, and when coding and categorizing data into themes is required. The paper outlines the Miles & Huberman (1994) model for thematic analysis, which includes three stages: data reduction, data display, and data drawing/conclusion. Data reduction involves selecting, simplifying, and transforming data, while data display organizes information to make sense of the data. Data drawing and conclusions involve interpreting the data to support participants' statements. The paper emphasizes the importance of validation and reliability in thematic analysis, suggesting the involvement of external reviewers to ensure the accuracy and consistency of themes. It also discusses the use of various data display techniques, such as tables, graphs, and quotations, to enhance the analysis. Thematic analysis is considered a flexible and systematic method for qualitative research, allowing researchers to explore complex data and generate meaningful insights. The paper concludes that thematic analysis is a suitable approach for studies where data is determined and defined before the study begins, and it provides a comprehensive process for identifying relationships between data and evolving themes.This paper critically reviews the use of thematic analysis (TA) in qualitative research, comparing it with grounded theory (GTA) and hermeneutic analysis.
