概要	Comparative Constructivist Grounded Theory combines Kathy Charmaz's constructivist strand of grounded theory with an explicit comparative design, deliberately collecting and analyzing data from two or more groups, settings, or time points to build a theory that accounts for variation and similarity across contexts. The constructivist perspective treats categories and theory as co-constructed between researcher and participants rather than discovered objectively from data.	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.
