Tóm tắt	Multiple case-based classic grounded theory (CGT) extends Glaser and Strauss's original inductive framework by grounding theory development simultaneously across two or more purposefully selected cases. Rather than studying a single site or participant group, the researcher treats each case as a distinct analytic unit while using the constant comparative method to draw cross-case theoretical insights. The goal is the same as in all classic GT: emergence of a substantive theory that explains the main concern of participants — but the multi-case structure broadens the conceptual base and supports more robust theoretical abstraction.	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.
