In This Issue: Intersectional Mixed Methods Research, Assessment Development and Validation Using Mixed Methods, Mixing Research and Religion, Mixed Methods and Clinical Practice Guidelines, and the Deductive-Inductive Dual Pillar Integration Process

This April issue of the Journal of Mixed Methods Research (JMMR) features an editorial, four articles, and a media review.In his editorial, Younas (2026) introduces intersectional mixed methods research and explains how this approach allows researchers to shift from a variablecentered approach to one better suited to elucidating complex social realities in which systems of oppression and power overlap.The author begins with an overview of the main features of intersectionality theory and then offers a rationale for integrating intersectionality into mixed methods research.As the literature on mixed methods and intersectionality is still scarce, we hope this editorial will help researchers recognize the importance of this approach in conducting equityfocused mixed methods studies.In the first article in this issue, Zhang and Browne (2026) report an empirical example of a multiphase mixed methods study to assess and understand scientific argumentation competence (SAC) among Chinese high school students.Using this example, the authors describe several methodological considerations about the theory-guided exchanges between integration and validation approaches that took place in their study.The paper contributes to the field of mixed methods by exploring connections between mixed methods and validation theory and providing concrete examples of innovative uses of joint displays in assessment development and validation.The authors explain the usefulness of validation theories in developing joint displays and suggest guidelines for the practice of mixed methods validation.
