概要	Concurrent intervention mixed methods is a research design that embeds qualitative data collection within an experimental or quasi-experimental intervention study, with both data strands gathered simultaneously during the intervention period. Quantitative data assess intervention outcomes while qualitative data illuminate participants' experiences, implementation processes, or contextual factors — each strand informing the other at the integration stage.	The multiphase mixed methods design is a sustained research program in which quantitative and qualitative strands are combined across three or more sequential phases — or across multiple related projects — to address a central program objective. Each phase builds on the prior phase's findings, making the design well-suited to long-term evaluation, intervention development, and large-scale program assessment where a single data-collection cycle cannot fully address the complexity of the research problem.
