Process evaluation of health promotion interventions

English This article uses two extended illustrations of current process evaluations to address areas of difficulty in health promotion design. There are no clear solutions to methodological problems that are rooted in competition between paradigms. Further,any design adopted must adapt to constraints of resources and time. Nevertheless, a multi-method approach can provide a pragmatic and realistic way forward, with the precise mix of methods selected being adapted to the particular requirements and constraints of the intervention project being evaluated.
