Tóm tắt	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.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.
