"I speak a different dialect": Teen Explanatory Models of Difference and Disability

Daley, Tamara, & Weisner, Thomas S. (2003)

Medical Anthropology Quarterly, 17(1): 25-48

fter eras of “blaming” parents for their children’s disabilities and relying on biomedical labels as both correct and sufficient to explain and name various conditions, research and practice today recognize the significance of the meaning and understanding of disabilities held by family members and children themselves. What do teens with disabilities believe about their circumstances, and what do they understand to be the causes, correlates, and consequences of their conditions? Elicited explanatory models from adolescents with varied cognitive disabilities and delay to better understand their personal experiences

A cross-sectional mixed methods study protocol to generate learning from patient safety incidents reported from general practice

Carson-Stevens et al (2015)

Incident reports contain descriptions of errors and harms that occurred during clinical care delivery. Few observational studies have characterised incidents from general practice, and none of these have been from the England and Wales National Reporting and Learning System. This study aims to describe incidents reported from a general practice care setting. A general practice patient safety incident classification will be developed to characterise patient safety incidents. A weighted-random sample of 12 500 incidents describing no harm, low harm and moderate harm of patients, and all incidents describing severe harm and death of patients will be classified. Insights from exploratory descriptive statistics and thematic analysis will be combined to identify priority areas for future interventions. The need for ethical approval was waivered by the Aneurin Bevan University Health Board research risk review committee given the anonymised nature of data (ABHB R&D Ref number: SA/410/13). The authors will submit the results of the study to relevant journals and undertake national and international oral presentations to researchers, clinicians and policymakers.

Mixed Methods Analysis and Information Visualization: Graphical Display for Effective Communication of Research Results

Onwuegbuzie, Anthony J. & Dickinson, W. B. (2008)

The Qualitative Report, 13(2), 204-225

Introduces a range of graphical methods that can be used to present mixed methods research results. Presents a taxonomy for the presentation of results in general (quan or qual) and then strategy for integrating qual-quant results in same framework. Frist, we present a broad taxonomy of visual representation. Next, we use this taxonomy to provide and overview of visual techniques for quantitative data display and qualitative data display. Then, we propose what we call "crossover" visual extensions to summarize and integrate both qualitative and quantitative results within the same framework.

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.

The Meaning of Kappa: Probabilistic Concepts of Reliability and Validity Revisited

Guggenmoos-Holzmann, Irene (1996)

Journal of Clinical Epidemiology, 49(7): 775-782

A Framework—the “agreement concept”—is developed to study the use of Cohen's kappa as well as alternative measures of chance-corrected agreement in a unified manner for qualitative and mixed methods research. Focusing on intrarater consistency it is demonstrated that for 2 × 2 tables an adequate choice between different measures of chance-corrected agreement can be made only if the characteristics of the observational setting are taken into account. In particular, a naive use of Cohen's kappa may lead to strinkingly overoptimistic estimates of chance-corrected agreement. Such bias can be overcome by more elaborate study designs that allow for an unrestricted estimation of the probabilities at issue. When Cohen's kappa is appropriately applied as a measure of chance-corrected agreement, its values prove to be a linear—and not a parabolic—function of true prevalence. It is further shown how the validity of ratings is influenced by lack of consistency. Depending on the design of a validity study, this may lead, on purely formal grounds, to prevalence-dependent estimates of sensitivity and specificity. Proposed formulas for “chance-corrected” validity indexes fail to adjust for this phenomenon. It is common practice to assess consistency of diagnostic ratings in terms of 'agreement beyond chance'. To explore the interpretation of such a term we consider relevant statistical techniques such as Cohen's kappa and log-linear models for agreement on nominal ratings. We relate these approaches to a special latent class concept that decomposes observed ratings into a class of systematically consistent and a class of fortuitous ratings. This decomposition provides a common framework in which the specific premises of Cohen's kappa and of log-linear models can be identified and put into perspective. As a result it is shown that Cohen's kappa may be an inadequate and biased index of chance-corrected agreement in studies of intra-observer as well as inter-observer consistency. We suggest a more critical use and interpretation of measures gauging observer reliability by the amount of agreement beyond chance.

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.
