The planning and reporting of mixed methods studies on the built environment and health

Researchers examining the influence of the built environment on health are increasingly using mixed methods approaches. The use of more than one type of methodology to address a single research question is compelling in this field because researchers investigating the impact of the built environment on health have been faced with proposing solutions to a complex societal problem involving interacting systems and social uncertainties. Mixed methods studies can help researchers to gain a better understanding of the relationships that exist between humans and their environment by drawing on qualitative and quantitative methods. Mixed methods studies could also be instrumental for providing effective policy solutions. This is because they allow researchers to identify built environment determinants of health in a population of interest and to understand the social and cultural factors that might influence the uptake of an intervention by this population. The objective of this paper is to assist those conducting research on the built environment and health who may have little background in mixed methods. We provide an overview of mixed methods research designs and provide concrete techniques for the integration of diverse methods. We also discuss the recommendations for mixed methods research in the field of built environment - health research, drawing on specific examples from published studies. Reporting a research design and an integration strategy in mixed methods studies could help to strengthen our ability to gain new insights into the multidimensional nature of the relationship between the built environment and health.
