Putting the "Mix" in Mixed Methods: How to Integrate Quantitative and Qualitative Research in Early Childhood Special Education Research

Mixed methods research (MMR) has the potential to be a powerful tool to expand the ways early intervention/early childhood special education (EI/ECSE) scholarship understands and informs practice. Integration, or the purposeful combination of quantitative and qualitative research approaches, is central for rigorous MMR. However, it can be challenging to identify and enact integration because integration processes and procedures can vary greatly depending on a study's purpose(s), design, and underlying philosophical assumptions and priorities. In this article, we offer guidance on ways EI/ECSE researchers can engage in meaningful and purposeful integration. We highlight three critical decision-making points: integration dimension or type, integration timing, and relative emphasis of methods when integrating. Additionally, we discuss related considerations to particularly ensure strong qualitative designs and integration within MMR.
