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.	Classic Grounded Theory (CGT) is a systematic qualitative methodology for generating substantive theory from empirical data. Developed by Barney Glaser and Anselm Strauss in 1967, it uses iterative cycles of data collection, constant comparison, and memo writing to produce a core category and surrounding conceptual framework that explains a social or psychological process. Unlike its later variants, Glaserian CGT insists on emergence — theory must arise from data without forcing preconceived frameworks.
