Toward A Unified Validation Framework In Mixed Methods Research, Amy B. Dellinger, Nancy L. Leech

Nancy Leech

The primary purpose of this article is to further discussions of validity in mixed methods research by introducing a validation framework to guide thinking about validity in this area. To justify the use of this framework, the authors discuss traditional terminology and validity criteria for quantitative and qualitative research, as well as present recently published validity terminology for mixed methods research. The authors discuss the rationale for their framework and how it unifies thinking about validity in mixed methods research. Finally, they discuss how the framework can be used.
