概要	Comparative classic grounded theory is a qualitative research design that applies Glaser and Strauss's original Glaserian grounded theory procedures across two or more deliberately selected comparison groups, settings, or time points. The constant comparative method — the analytical engine of classic GT — is extended systematically across sites so that the emerging substantive theory accounts for variation in the phenomenon across different contexts, populations, or conditions.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
