The Use of Mixed Methods in Research
Abstract
Mixed methods research is becoming increasingly popular and is widely acknowledged as a means of achieving a more complex understanding of research problems. Combining both the in-depth, contextual views of qualitative research with the broader generalizations of larger population quantitative approaches, mixed methods research can be used to produce a rigorous and credible source of data. Using this methodology, the same core issue is investigated through the collection, analysis, and interpretation of both types of data within one study or a series of studies. Multiple designs are possible and can be guided by philosophical assumptions. Both qualitative and quantitative data can be collected simultaneously or sequentially (in any order) through a multiphase project. Integration of the two data sources then occurs with consideration is given to the weighting of both sources; these can either be equal or one can be prioritized over the other. Designed as a guide for novice mixed methods researchers, this chapter gives an overview of the historical and philosophical roots of mixed methods research. We also provide a practical overview of its application in health research as well as pragmatic considerations for those wishing to undertake mixed methods research.
