Tóm tắt	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.	Comparative Straussian Grounded Theory applies the systematic open–axial–selective coding framework of Strauss and Corbin across two or more purposively selected contexts, groups, or sites to generate theory that explains both within-context processes and cross-context variation. The constant comparative method — the analytic engine first described by Glaser and Strauss (1967) — is elevated to a deliberate design-level strategy, allowing researchers to build mid-range theory that accounts for how social processes unfold differently under varying conditions.
