概要	Participatory multiple case study research integrates the structured logic of multiple case study design — examining two or more bounded cases to build analytic generalisations — with the collaborative ethics of participatory research, where community members or practitioners co-design the inquiry, co-collect data, and co-interpret findings. The approach combines Yin's replication logic across cases with the emancipatory and co-ownership principles that define participatory action research traditions.	A participatory single case study is a qualitative design that examines one bounded case in depth while actively involving community members, practitioners, or participants as co-researchers throughout the inquiry. It blends Yin's case study rigor — triangulated evidence, thick description of context — with participatory action research values of collaboration, equity, and action. The result is both a rich, contextual understanding of the case and a knowledge-building process that serves the people within it.
