概要	A quantitative-dominant multiphase mixed methods design conducts a series of distinct research phases — at least two, often three or more — in which quantitative data and analyses bear the primary weight of answering the research questions, while qualitative components serve a supporting or explanatory role. Phases are linked by explicit integration points where findings from one phase inform the design or interpretation of the next.	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.
