概要	Comparative Thematic Analysis applies the structured procedures of thematic analysis across two or more distinct groups, sites, or time points, with the explicit aim of identifying both shared patterns and meaningful differences. Rather than producing a single composite account of experience, it yields a layered analysis that maps where themes converge and diverge across comparison units — making it especially valuable for policy-relevant, cross-cultural, or multi-site qualitative studies.	Reflexive Thematic Analysis (RTA) is a widely used qualitative method for identifying, analysing, and interpreting patterns of shared meaning — called themes — across a dataset. Developed by Virginia Braun and Victoria Clarke, it is theoretically flexible, works across epistemological positions, and foregrounds the researcher's active, interpretive role rather than treating themes as features that simply emerge from data. It differs from older 'codebook' approaches by treating the analyst's subjectivity as a resource rather than a source of bias to be suppressed.
