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.	Constructivist Grounded Theory (CGT) is a qualitative methodology developed by Kathy Charmaz that systematically builds mid-range theory from empirical data through iterative coding, memo-writing, and theoretical sampling. Unlike the original objectivist version by Glaser and Strauss, CGT treats both data and theory as co-constructed between researcher and participants, acknowledging the researcher's interpretive perspective as an integral part of the analytic process rather than a source of bias to be eliminated.
