Tóm tắt	The sequential exploratory mixed methods design begins with a qualitative phase to explore a poorly understood phenomenon, then builds on those findings in a second quantitative phase — most commonly to develop and test a measurement instrument, or to test whether themes identified qualitatively generalise across a broader population. The two phases are conducted in sequence, with qualitative results explicitly informing the design and content of the quantitative strand.	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.
