This chapter discusses issues of quality (or scientific rigor) in mixed methods research. In the first section, we summarise common standards of quality and appraisal criteria that apply in both qualitative and quantitative studies. The next section presents a critical appraisal framework for quality that is uniquely relevant to designing and conducting mixed methods research. Finally, we describe potential methodological threats to quality that arise from decisions related to sampling, data collection, analysis, interpretation, and presentation in mixed methods studies.
