Clustering Methods with Qualitative Data: a Mixed-Methods Approach for Prevention Research with Small Samples

David Henry, Allison B. Dymnicki, Nathaniel Mohatt, James Allen, James G. Kelly (2015)

Qualitative methods potentially add depth to prevention research but can produce large amounts of complex data even with small samples. Studies conducted with culturally distinct samples often produce voluminous qualitative data but may lack sufficient sample sizes for sophisticated quantitative analysis. Currently lacking in mixed-methods research are methods allowing for more fully integrating qualitative and quantitative analysis techniques. Cluster analysis can be applied to coded qualitative data to clarify the findings of prevention studies by aiding efforts to reveal such things as the motives of participants for their actions and the reasons behind counterintuitive findings. By clustering groups of participants with similar profiles of codes in a quantitative analysis, cluster analysis can serve as a key component in mixed-methods research. This article reports two studies. In the first study, we conduct simulations to test the accuracy of cluster assignment using three different clustering methods with binary data as produced when coding qualitative interviews. Results indicated that hierarchical clustering, K-means clustering, and latent class analysis produced similar levels of accuracy with binary data and that the accuracy of these methods did not decrease with samples as small as 50. Whereas the first study explores the feasibility of using common clustering methods with binary data, the second study provides a “real-world” example using data from a qualitative study of community leadership connected with a drug abuse prevention project. We discuss the implications of this approach for conducting prevention research, especially with small samples and culturally distinct communities.

Toward a Definition of Mixed Methods Research

Johnson, R. Burke, Onwuegbuzie, Anthony J., & Turner, Lisa A. (2007)

Journal of Mixed Methods Research, 1(2), 112-133

Examines the definition of the emerging mixed methods research field. Surveyed major authors in the mixed method literature with regard to definition for the field and key issues that need to be addressed as the field advances. Results show a consensus of mixed methods as an emerging ‘research paradigm’ and a breadth of opinion around definition for the field.

Integrating Survey and Ethnographic Methods for Systematic

Pearce, L. D. (2002)

Sociological Methodology, 32(1): 103-132

How the salience of research findings can be enhanced by combining survey and ethnographic methods to draw insight from anomalous cases. Using examples from a research project examining the influence of religion on childbearing preferences in Nepal, the author illustrates how survey data can facilitate the selection of ethnographic informants and how semistructured interviews with these deviant cases leads to improved theory, measures, and methods.

Barriers to Integrating Quantitative and Qualitative Research

Bryman, A. (2007)

Journal of Mixed Methods Research, 1(1): 8-22

This article is concerned with the possibility that the development of mixed methods research is being hindered by the tendency that has been observed by some researchers for quantitative and qualitative findings either not to be integrated or to be integrated to only a limited extent. It examines findings from 20 interviews with U.K. social researchers, all of whom are practitioners of mixed methods research. From these interviews, a wide variety of possible barriers to integrating mixed methods findings are presented. Challenges to integrating mixed methods data and strategy for writing mixed methods research articles.

Focus Groups

Morgan, David L. (2004)

S. N. Hesse-Biber and P. Leavy (Eds.), Approaches to Qualitative Research: A Reader on Theory and Practice, pp. 263-285. New York, NY: Oxford University Press

Written a long-time authority on focus group, presents a brief history of focus group application up to, and including, information on the variety of current uses across many disciplines. Great section on the uses of focus groups in combination with other methods with a full compare/contrast discussion. Finally, goes into the specifics on ‘how to’ plan and conduct effective group data collection.

Reliability in Coding Open-Ended Data: Lessons Learned from HIV Behavioral Research

Hruschka, D. J., Schwartz, D., St. John, D. C., Picone-Decaro, E., Jenkins, R. A., & Carey, J. W. (2004)

Field Methods, 16(3): 307-331

Great discussion and illustration of issues and strategy for establishing reliability in inter-rater coding. Intercoder reliability is a measure of agreement among multiple coders for how they apply codes to text data. Intercoder reliability can be used as a proxy for the validity of constructs that emerge from the data.

Unleashing Frankenstein’s Monster? The Use of Computers in Qualitative Research.

Hesse-Biber, Sharlene (2004)

H. R. Bernard (Ed.), Handbook of Methods in Cultural Anthropology, pp. 549-593. In S. N. Hesse-Biber and P. Leavy (Eds.), Approaches to Qualitative Research: A Reader on Theory and Practice, pp. 535-545.

The use of qualitative data analysis software has been increasing in recent years. A number of qualitative researchers have raised questions concerning the effect of such software in the research process. Fears have been expressed that the use of the computer for qualitative analysis may interfere with the relationship between the researcher and the research process itself by distancing the researcher from both the data and the respondent. Others have suggested that the use of a quantitative tool, the computer, would lead to data dredging, quantification of results, and loss of the "art" of qualitative analysis. In this study of 12 qualitative researchers, including both faculty members and graduate students, we have found that these fears are exaggerated. Users of qualitative data analysis software in most cases use the computer as an organizational, time-saving tool and take special care to maintain close relationships with both the data and the respondents. It is an open question, however, whether or not the amount of time and effort saved by the computer enhance research creativity. The research findings are mixed in this area. At issue is the distinction between creativity and productivity when computer methods are used. Computer packages targeted at qualitative and mixed methods researcg data are readily available and the methodology sections of research articles indicate that they are being utilised by some health researchers. The purpose of this article is to draw together concerns which have been expressed by researchers and critics and to place these within the perspective of 'framing' (MacLachlan & Reid, 1994). Here, the focus becomes the frame that these computer programs impose on qualitative data. Inevitably, all data sets are disturbed by the techniques of collection and the conceptual and theoretical frames imposed, but computer framing not only distorts physically but also imposes an often minimally acknowledged frame constructed by the metaphors and implicit ideology of the program. This frame is in opposition to most of the recent changes in qualitative data interpretation, which have emphasised context, thick description and exposure of the minimally disturbed voices of participants.

Scientific Foundations of Qualitative Research

Ragin, Charles C., Nagel, Joane, & White, Patricia (2004)

National Science Foundation Report

Report generated by a NSF workshop on qualitative research methods. Two main sections: 1) provide a general guidance for developing qualitative research project and 2) recommendations for strengthening qualitative research. This report is organized into two major sections — general guidance for developing qualitative research projects and recommendations for strengthening qualitative research. The intent of the first section of the report is to serve as a primer to guide both investigators developing qualitative proposals and reviewers evaluating qualitative research projects. The second section of the report presents workshop recommendations for designing, evaluating, supporting, and strengthening qualitative research.

Interobserver Agreement, Reliability, and Generalizability of Data Collected in Observational Studies

Mitchell, Sandra K. (1979)

Psychological Bulletin, 86(2): 376-390

Research in developmental and educational psychology has come to rely less on conventional psychometric tests and more on records of behavior made by human observers in natural and quasi-natural settings. Discusses reliability and generalizability in terms of coefficients that reflect the "quality" of data, what defines quality data, and how reports of agreement are insufficient.
