概要	Equal-weight pragmatic mixed methods is a research design in which quantitative and qualitative strands are assigned the same methodological priority (QUAL = QUAN) and conducted from a pragmatist philosophical stance. Rather than privileging one paradigm, the researcher selects and combines methods that best answer the research question — treating practical utility as the primary criterion for all design decisions.	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.
