Paradigms Lost and Pragmatism Regained: Methodological Implications of Combining Qualitative and Quantitative Methods

Morgan, D. L. (2007)

Journal of Mixed Methods Research, 1(1): 48-76

This article examines several methodological issues associated with combining qualitative and quantitative methods by comparing the increasing interest in this topic with the earlier renewal of interest in qualitative research during the 1980s. Background on the emergence of mixed method research approaches and suggestions for guiding paradigm shift toward 'pragmatic' approaches in social science research.

Meta-integration for synthesizing data in a systematic mixed studies review: insights from research on autism spectrum disorder

Frantzen, Kirsten Krabek; Fetters, Michael D. (2015)

Systematic reviews conducted using either meta-analysis or meta-synthesis are well established methodological procedures for combining data and results across different quantitative or qualitative studies. Recently, a third option for systematic reviews has emerged. Systematic mixed studies reviews combine data and results across quantitative, qualitative and mixed method studies. An important challenge is how to integrate the quantitative, qualitative and mixed method studies. Here, we introduce the concept of “meta-integration”. Our overarching aim is to define and illustrate the novel concept of meta-integration as applied to convergent systematic mixed studies reviews using examples from our research on parental self-perception and autism spectrum disorder. Specifically, we present a typology for meta-integration procedures at two levels, both basic and advanced meta-integration. Three models, namely, basic convergent meta-integration, basic convergent qualitative meta-integration, and basic convergent quantitative meta-integration, combine quantitative and qualitative studies. Three additional models, namely, advanced convergent qualitative meta-integration, advanced convergent qualitative meta-integration, and advanced convergent quantitative meta-integration, combine quantitative, qualitative and mixed method studies. The models generally follow six steps: (1) categorize data sources; (2) transform the data; (3) conduct intra-method synthesis; (4) conduct inter-method synthesis and/or integration; (5) organize results and assess fit; and (6) draw final conclusions. One basic and one advanced model do not involve data transformation. These models for conducting convergent meta-integration in systematic mixed studies reviews provide guidance for researchers to apply rigorous and coherent methodology. Following these procedures can substantively improve the quality of systematic reviews seeking to use quantitative, qualitative and mixed method studies.

Measures of Interobserver Agreement: Calculation Formulas and Distribution Effects

House, Alvin E., House, Betty J., & Campbell, Martha B. (1981)

Calculation formulas and distribution effects Journal of Behavioral Assessment, 3(1): 37-57

Discusses issues, types, and calculations for inter-rater reliability. Seventeen measures of association for observer reliability (interobserver agreement) are reviewed and computational forumals are given in a common notational system. An empirical comparison of 10 of these measures is made over a range of potential reliability check results.

Mapping the Field of Mixed Methods Research

Creswell, John W. (2009)

Journal of Mixed Methods Research, 3(2), 95-108

Terrific survey of what’s happening in the mixed methods literature and mixed methods field. Discusses a range of topics raised at the 2008 Mixed Methods Conference and provides a “Map” of these topics broken out across 5 domains: philosophical/theoretical, techniques, nature of mixed methods, the adoption and use of mixed methods, and the politicization of mixed methods. Concludes with a discussion of incorporating mixed methods into other designs, paradigms, general design issues, and advocacy through extramural funding.

A Mixed Methods Investigation of Mixed Methods Sampling Designs in Social and Health Science Research

Collins, Kathleen M. T., Onwuegbuzie, Anthony J., & Jiao, Qun G. (2007)

Journal of Mixed Methods Research, 1(3), 267-294

Presents a two-dimensional model (time orientation—concurrent vs. sequential and the relationship between the qualitative and quantitative samples—identical, nested, multilevel, and parallel) for classifying mixed methods studies sampling designs. Presents and discusses findings from the distribution of 121 studies into the model and the relative appropriateness of the employed strategy.

Introduction to Mixed Method and Mixed Model Studies in the Social and Behavioral Sciences: Paradigm Wars and Mixed Methodologies.

Tashakkori, Abbas & Teddlie, Charles (1998)

A. Tashakkori & C. Teddlie, Mixed Methodology: Combining Qualitative and Quantitative Approaches, pp. 20-39.

Encourages a focus on the research question as a guide to deciding on methods to apply in a particular study and comfort in cross the boundaries between pure interpretations of particular paradigmatic characteristics. Describes the nature and limitation of various mono-methods. Suggests that incorporating a pragmatic approach with a variety of appropriate methods helps gain a broader and more comprehensive perspective on the research question.

Integrating Quantitative and Qualitative Research: How is it Done?

Bryman, Alan (2006)

Qualitative Research, 6(1), 97-113

This article seeks to move beyond typologies of the ways in which quantitative and qualitative research are integrated to an examination of the ways that they are combined in practice. Draws on a content analysis of methods and design from 232 articles using combined methods. Examine and discusses the rationales provide for employing mixed-methods and whether they correspond to actual practice.

Research Design Issues for Mixed Method and Mixed Model Studies

Tashakkori, Abbas & Teddlie, Charles (1998)

A. Tashakkori & C. Teddlie, Mixed Methodology: Combining Qualitative and Quantitative Approaches, pp. 40-58. Thousand Oaks, CA: Sage Publications

Discusses the concept of triangulation from various perspectives and the variety of approaches to implementing mixed methods research. Builds on Patton’s (1990) discussion of ‘mixed form’ design to a broader model in order to develop a taxonomy for distinguishing various mixed method designs and approaches.

Advances in mixed methods research

Bergman, M. M (2008)

London: Sage

Advances in Mixed Methods Research provides an essential introduction to the fast-growing field of mixed methods research. Bergman's book examines the current state of mixed-methods research, exploring exciting new ways of conceptualizing and conducting empirical research in the social and health sciences. Illuminating new ways of conceptualizing and conducting empirical research in the social sciences and humanities, this book contains contributions from some of the world's leading experts on qualitative, quantitative, and mixed methods approaches. The contributions cover all of the main practical and methodological issues and represent a number of different visions of what mixed methods research is and where it is going. Contributions from the world's leading experts in qualitative, quantitative, and mixed methods approaches are brought together, clearing the way for a more constructive approach to social research. These contributions cover the main practical and methodological issues and include a number of different visions of what mixed methods research is. The discussion also covers the use of mixed methods in a diverse range of fields, including sociology, education, politics, psychology, computational science and methodology. This book represents an important contribution to the ongoing debate surrounding the use of mixed methods in the social sciences and health research, and presents a convincing argument that the conventional, paradigmatic view of qualitative and quantitative research is outdated and in need of replacement. It will be essential reading for anyone actively engaged in qualitative, quantitative and mixed methods research and for students of social research methods. Manfred Max Bergman is Chair of Methodology and Political Sociology at the University of Basel. Very good text wherein the mixed methods approach is coherently developed and its current (and potential) applications are described in clear, useful and interesting ways. I particularly liked the depth of understanding with Bergman demonstrating subtle implications of the advances. For the undergraduate level, I felt this was perhaps too advanced but well worth a read if the mixed methods approach is adopted. Mr Paul Buckley Nursing , Bradford University
