概要	Participatory concurrent triangulation mixed methods is a research design that embeds a participatory worldview — prioritising community involvement, co-ownership, and social change — within a concurrent triangulation structure, in which quantitative and qualitative data are collected at the same time, analysed independently, and then merged to compare or validate findings. The design is used when researchers need both statistical breadth and lived-experience depth, and when the community affected by the research must be meaningfully involved throughout.	Participatory Action Research (PAR) is a qualitative, community-centred methodology in which researchers and community members collaborate as co-investigators to identify a shared problem, take deliberate action, observe outcomes, and reflect critically on results — cycling iteratively until meaningful change is achieved. Unlike conventional research that studies people from the outside, PAR treats participants as active agents who co-own the research process, the knowledge produced, and the practical interventions that follow.
