Intervention Research Approaches
This article reviews the process of intervention research, with particular emphasis on interventions with and for older adults. First, we consider the context of intervention research: What are the resources and constraints that shape the process of intervention and research? Second, we outline a taxonomy of interventions, reflecting different combinations of level and timing of interventions. Third, we consider the types of research designs that are most appropriate in the different contexts of applied research.
