Evaluating Mixed Research Studies: A Mixed Methods Approach, Nancy L. Leech, Amy B. Dellinger, Kim B. Brannagan, Hideyuki Tanaka

Nancy Leech

The purpose of this article is to demonstrate application of a new framework, the validation framework (VF), to assist researchers in evaluating mixed research studies. Based on an earlier work by Dellinger and Leech, a description of the VF is delineated. Using the VF, three studies from education, health care, and counseling fields are evaluated. The three mixed research studies differed in design and implementation. Elements of the VF were examined and evaluated for each study, and a picture of the quality of each study was captured textually. In presenting the VF and its potential for practical application in evaluating …

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.

Validity And Qualitative Research: An Oxymoron?, Anthony J. Onwuegbuzie, Nancy L. Leech

Nancy Leech

Although the importance of validity has long been accepted among quantitative researchers, this concept has been an issue of contention among qualitative researchers. Thus, the first purpose of the present paper is to introduce the Qualitative Legitimation Model, which attempts to integrate many of the types of validity identified by qualitative researchers. The second purpose of this article is to describe 24 methods for assessing the truth value of qualitative research. Utilizing and documenting such techniques should prevent validity and qualitative research from being seen as an oxymoron.
