1 Developments (last 20 years) Increasing interest in and advocacy for mixed methods Evolving understanding of what is mixed methods research Developing designs and innovative techniques “The emergence of mixed methods as a third methodological movement in the social and behavioral sciences began during the 1980’s.” (Tashakkori & Teddlie, 2003: 697)
2
2 Development of NIH guidelines (1999) - Mentioned several approaches for combining qualitative and quantitative research - Advanced considerations for deciding what model to use (literature available, prior studies, realistic design, expertise) - Suggested to describe each method thoroughly “Combining qualitative and quantitative methods has gained broad appeal in public health research.” (1999)

3 14+ books on mixed methods research have been written since 1988 Books on Mixed Methods Research

6 Critics (Creswell, 2007) Is there a post-positivist leaning to mixed methods? Howe, K. R. (2004). A critique of experimentalism. Qualitative Inquiry, 10, 42-61. Giddings, L. S. (2006). Mixed-methods research: Positivism dressed in drag? Journal of Research in Nursing, 11(3), 195-2003. Holmes, C. A. (2007). Mixed(up) methods, methodology and interpretive frameworks. Contributed paper for the Mixed Methods Conference, Cambridge, University, July 10-12, 2006. What are the limits for mixed methods research? Sale, J. E. M., Lohfeld, L. H., Brazil, K. (2002). Revisiting the quantitative-qualitative debate: Implications for mixed-methods research. Quality and Quantity, 36, 43-53. Leahey, E. (2007). Convergence and confidentiality? Limits to the implementation of mixed methodology. Social Science Research, 36, 149-158. Is there a dominant discourse in mixed methods research? Freshwater, D. (2007).

11
11 Mixing – Why? Validity – to corroborate quan and qual data Offset – offset weaknesses of quan and qual and draw on strengths Completeness – more comprehensive account that qual or quan alone Process – quan provides outcomes; qual, the processes Explanation – qual can explain quan results or vice-versa Unexpected results – surprising results from one, other explains Instrument development – qual employed to design instrument Credibility – both approaches enhance integrity of findings Context – qual provides context; quan provides general. Utility – more useful to practitioners

12 Smith & Heshusius, (1986) “Incompatibility thesis” “The contention of this paper is that the claim of compatibility, let alone one of synthesis, cannot be sustained.” (p. 4) Purist Stance
13
13 “ Single” Paradigm Stance Pragmatism (Tashakkori & Teddlie, 2003) Focus on research question What “works,” consequences Multiple methods – large toolkit Transformative (Mertens, 2003) Transform lives of underrepresented, marginalized groups Incorporate this focus into all phases of research
