概要	Longitudinal Reflexive Thematic Analysis (L-RTA) applies Braun and Clarke's reflexive thematic analysis framework to qualitative data collected from the same participants (or context) at two or more time points. Rather than producing a single static account, it tracks how meanings, experiences, and themes evolve, persist, or transform over time, foregrounding the researcher's active reflexive engagement at every stage of the iterative process.	Interpretive Reflexive Thematic Analysis applies Braun and Clarke's reflexive thematic analysis framework explicitly within an interpretivist epistemological stance. The analyst treats meaning as co-constructed between researcher and data, foregrounds their own subjective positionality throughout the coding and theming process, and produces theoretically rich accounts of participant perspectives rather than surface-level content summaries. It is among the most widely used analytical approaches in contemporary qualitative research.
