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.

The impact of music therapy versus music medicine on psychological outcomes and pain in cancer patients: a mixed methods study

Joke Bradt, Noah Potvin, Amy Kesslick, Minjung Shim, Donna Radl, Emily Schriver, Edward J. Gracely, Lydia T. Komarnicky-Kocher (2015)

The purpose of this study was to compare the impact of music therapy (MT) versus music medicine (MM) interventions on psychological outcomes and pain in cancer patients and to enhance understanding of patients’ experiences of these two types of music interventions. This study employed a mixed methods intervention design in which qualitative data were embedded within a randomized cross-over trial. Thirty-one adult cancer patients participated in two sessions that involved interactive music making with a music therapist (MT) and two sessions in which they listened to pre-recorded music without the presence of a therapist (MM). Before and after each session, participants reported on their mood, anxiety, relaxation, and pain by means of visual analogue and numeric rating scales. Thirty participants completed an exit interview. The quantitative data suggest that both interventions were equally effective in enhancing target outcomes. However, 77.4 % of participants expressed a preference for MT sessions. The qualitative data indicate that music improves symptom management, embodies hope for survival, and helps connect to a pre-illness self, but may also access memories of loss and trauma. MT sessions helped participants tap into inner resources such as playfulness and creativity. Interactive music making also allowed for emotional expression. Some participants preferred the familiarity and predictability of listening to pre-recorded music. The findings of this study advocate for the use of music in cancer care. Treatment benefits may depend on patient characteristics such as outlook on life and readiness to explore emotions related to the cancer experience.

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.

The health perspectives of Australian adolescents from same-sex parent families: a mixed methods study

S. R. Crouch, E. Waters, R. McNair, J. Power (2014)

Research involving adolescents from same-sex parent families provides an important contribution to the evidence base on their health, well-being and the impact of stigma. To date reports on the perspectives of adolescents with same-sex attracted parents have been limited. This study aimed to describe the multidimensional experiences of physical, mental and social well-being of adolescents living in this context. A mixed methods study of adolescents with same-sex attracted parents comprising of an adolescent-report survey of 10- to 17-year-olds and family interviews with adolescents and their parents. Data were collected in 2012 and 2013 as part of the Australian Study of Child Health in Same-Sex Families. The findings from qualitative interviews with seven adolescents and responses to an open-ended survey question (n = 16) suggest four themes: perceptions of normality, positive concepts of health, spheres of life (including family, friends and community) and avoiding negativity. The quantitative sample of adolescents with same-sex attracted parents (n = 35) reported higher scores than population normative data on the dimensions general health and family activities within the Child Health Questionnaire (CHQ) as well as higher on the peer problems scale on the Strengths and Difficulties Questionnaire (SDQ). Perceived stigma correlates with lower health and well-being overall. Positive health outcomes are informed by the ways adolescents conceptualize health and how they construct their spheres of life. Peer relationships, and community perspectives of same-sex families, inform perceived stigma and its correlation with poorer health and well-being. Although adolescents see their families as essentially normal they are negatively affected by external societal stigma.

Intercoder Reliability for Validating Conclusions Drawn from Open-Ended Interview Data

Kurasaki, Karen S. (2000)

Field Methods, 12(3): 179-194

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. Popular methods for establishing intercoder reliability involve presenting predetermined text segments to coders. Using this approach, researchers run the risk of altering meanings by lifting text from its original context, or making interpretations about the length of codable text. This article describes a set of procedures that was used to develop and assess intercoder reliability with free-flowing text data, in which the coders themselves determined the length of codable text segments. Discusses procedures for developing and assessing intercoder reliability with free-flowing text.

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.

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.
