สรุป	Comparative qualitative content analysis (comparative QCA) applies a systematic, category-driven reading of texts or documents across two or more cases, groups, time periods, or cultural contexts, with the explicit goal of identifying similarities, differences, and patterns that emerge from the comparison. It combines the interpretive rigour of qualitative content analysis with a structured comparative logic, making it valuable for cross-national policy research, media studies, and any inquiry that requires principled comparison of meaning across contexts.	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.
