Advanced Mixed Methods Research Design

Dellinger, Amy B. & Leech, Nancy L. (2002)

Thousand Oaks: Sage Publication, In A. Tahakkori and C. Teddlie (Eds), Handbook of Mixed Methods Research Designs, pp. 209-239

Describes variety of mixed methods research designs and associated analytical issues. Related work: Evaluating Mixed Research Studies: A Mixed Methods Approach Nancy L. Leech, Amy B. Dellinger, Kim B. Brannagan and Hideyuki Tanaka4 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 mixed research studies, pragmatic researchers can use this tool to increase the quality of their evaluations of mixed research studies. Implementing Quality Criteria in Designing and Conducting a Sequential QUAN → QUAL Mixed Methods Study of Student Engagement With Learning Applied Research Methods Online Nataliya V. Ivankova In spite of recent methodological developments related to quality assurance in mixed methods research, practical examples of how to implement quality criteria in designing and conducting sequential QUAN → QUAL mixed methods studies to ensure the process is systematic and rigorous remain scarce. This article discusses a three-step procedure for securing the quality of the meta-inferences generated from sequential employment of quantitative and qualitative methods and offers several validation strategies specific to a sequential QUAN → QUAL mixed methods design: applying a systematic process for selecting participants for qualitative follow-up, elaborating on unexpected quantitative results, and observing interaction between qualitative and quantitative study strands. The discussed procedures are illustrated using a mixed methods study of graduate student engagement in learning applied research methods online.

Validity and Reliability of Qualitative Data Analysis: Interobserver Agreement in Reconstructing Interpretative Frames

Moret, Margriet, Reuzel, Rob, Van Der Wilt, Gert J. & Grin, John (2007)

Field Methods, 19(1): 24-39

Many authors have discussed criteria for assessing the quality of qualitative and mixed methods studies in the social sciences. However, relatively few have presented the results of using criteria for validity of qualitative studies. We investigated the quality of reconstructing interpretative frames, a method for analyzing interview transcripts. The aim of this method is to describe a person's perspective, distinguishing between perceived problem definitions, proposed solutions, empirical background theories, and normative preferences. Based on this description, one should be able to estimate this person's cooperation on implementing specific changes in his or her practice. In this article, we assessed the interobserver reliability of this analytical method as an indicator of its rigor. Six analysts reconstructed interpretative frames on the basis of verbatim transcripts of three interviews. The analysts agreed only moderately about the issues identified and which problems should be prioritized. However, they showed remarkable unanimity as to the estimates of the respondents' cooperation on proposed solutions.

Mixing Qualitative and Quantitative Research in Developmental Science: Uses and ,Methodological Choices

Yoshikawa, H., Weisner, T. S., Kalil, A., & Way, N. (2008)

Developmental Psychology, 44(2): 344-354

Describes and discusses choices for using mixed methods from a practical perspective and discusses common pitfalls and how to aviod them. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of “when” and “how.”

Distinguishing the Trees from the Forest: Applying Cluster Analysis to Thematic Qualitative Data

Guest, Greg & McLellan, Eleanor (2003)

Field Methods, 15(2): 186-201

Qualitative data analysis requires organizing and synthesizing often large quantities of text. In many cases, this analysis entails negotiating the interplay between raw data, semantic themes or codes, and the overarching conceptual framework. In this article, the authors use a case study, which examines HIV vaccine efficacy trial participants' discourse, to demonstrate how cluster analysis can be used to aid in the analysis of large qualitative data sets. After briefly reviewing the systematic approaches to qualitative analysis and describing the project background, the authors present an example of how a hierarchical cluster technique can be incorporated into a multistage thematic analysis. Cited by Macia In this article I discuss cluster analysis as an exploratory tool to support the identification of associations within qualitative data. While not appropriate for all qualitative projects, cluster analysis can be particularly helpful in identifying patterns where numerous cases are studied. I use as illustration a research project on Latino grievances to offer a detailed explanation of the main steps in cluster analysis, providing specific considerations for its use with qualitative data. I specifically describe the issues of data transformation, the choice of clustering methods and similarity measures, the identification of a cluster solution, and the interpretation of the data in a qualitative context.

Techniques to Identify Themes

W., & Bernard, H. Russell (2003)

Field Methods, 15(1): 85-109

Theme identification is one of the most fundamental tasks in qualitative research. It also is one of the most mysterious. Explicit descriptions of theme discovery are rarely found in articles and reports, and when they are, they are often relegated to appendices or footnotes. Techniques are shared among small groups of social scientists, but sharing is impeded by disciplinary or epistemological boundaries. This is a wonderful guide to describing and identifying themes in qualitative research.
