สรุป	Comparative grounded theory applies the systematic inductive logic of grounded theory across two or more distinct groups, settings, or time points. Rather than generating a theory grounded in a single context, it builds theory that explains variation and similarity across contexts, producing conceptually richer and more transferable explanatory frameworks than single-site grounded theory studies.	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.
