In more detail
Braun and Clarke distinguish reflexive thematic analysis from codebook approaches, such as template analysis and framework analysis. Codebook approaches develop a structured set of codes, often early in the analysis, and use it to guide coding, sometimes with several coders working to the same list.
Reflexive thematic analysis does not use a codebook in that sense. Codes evolve as the researcher reads, and there is no measure of agreement between coders. Researchers using reflexive thematic analysis still keep careful records of their codes and definitions, but as an account of developing thinking rather than a rulebook.
Which approach suits a study depends on its questions and its philosophical position. Braun and Clarke (2021) set out how the approaches differ.
In Themescape
Themescape displays coding from either approach. The Framework tab holds a working definition for each theme, code and sub-code, which a codebook study can use to keep its definitions beside the data. Example figures in the gallery are labelled reflexive, codebook or other.
