The benefits of combined (mixed) methods research

Abstract

In this paper I argue for the importance of combined (mixed) methods studies when evaluating complex initiatives such as interventions. These studies combine quantitative and qualitative methods purposively, in order to capture a broader range of important variables than can be examined by either quantitative or qualitative methods alone. In essence, a combined methods study can address outcomes and outputs, and also provide evidence on the processes that are important to optimising success. A large scale Government funded initiative is used as an example. The Parenting Early Intervention Pathfinder introduced parenting programmes into 18 local authorities. Quantitative data showed the scale of the support, and the significant improvements made in parenting skills and mental well-being, and in child behaviour. Qualitative data explored the factors optimising successful implementation. The evidence from the study was used to inform the decision to roll out evidence-based parenting programmes across the whole of England.
