Quality Issues in Mixed-Methods Research Alan Bryman, Management Centre, University of Leicester, UK.
Quality Criteria in Qualitative Research • Significant development • Inappropriateness of traditional criteria • Two approaches • Adapt traditional criteria • Alternative criteria
What about Mixed-Methods Research? • No criteria for appraising mixed-methods research exist (Sale and Brazil, 2004) • How should we approach quality criteria for mixed-methods research?
Three Possible Approaches • Convergent criteria • Separate criteria • Bespoke criteria • Problem of lack of agreement on qualitative criteria • Not a focus of concern among interviewees
A Contingency Approach • Insight from organization studies • Each approach to quality criteria may be appropriate in some circumstances but not others
Quantitative or Qualitative Dominant • Quantitative dominant – qualitative research generates hypotheses to be tested or to develop measurement instruments • Traditional criteria • Qualitative dominant - quantitative research simply for background data or amount of quantitative data is minimal • Alternative, qualitative criteria • Convergent criteria – use same criteria for both components
Integrated or Separate? • Different research questions for quantitative and qualitative components? • Separate criteria • Integration of quantitative and qualitative components • Bespoke criteria
Bespoke Criteria • Two sets of criteria • Tashakkori & Teddlie (2003) – emphasis on inference quality • Does an inference meets the fundamental criteria required for it to be credible and/or defensible? • Blends internal validity (traditional) and trustworthiness and credibility (alternative)
Bespoke Criteria • Sale & Brazil (2004) • Truth value = internal validity + credibility • Applicability = external validity/ generalizability + transferability • Consistency = reliability + dependability • Neutrality = objectivity + confirmability • Rooted in criteria for quantitative and qualitative research • Other criteria specific to mixed-methods? • Not always appropriate or needed anyway
Bespoke Criteria • Appear to be obvious solution but… • Not always appropriate • Lack of agreed qualitative criteria • Unplanned outcomes of mixed-methods research • Formulation of bespoke criteria for mixed-methods research very difficult
