概要	Qualitative-dominant intervention mixed methods is a research design in which qualitative inquiry carries primary theoretical and interpretive weight while quantitative data provide supplementary evidence, both strands applied within an intervention or program context. The design is used when understanding the lived experience of participants, the mechanisms of an intervention, and the meaning-making around change are more central to the research purpose than measuring effect sizes alone.	Intervention mixed methods design embeds qualitative data collection within an experimental or quasi-experimental study so that process, mechanism, and participant experience are captured alongside outcome measurement. The quantitative strand tests whether the intervention works; the qualitative strand explains how and why it works — or does not. The two strands may be sequenced before, during, or after the intervention phase, or run concurrently, depending on the research questions.
