Youth Physical Activity Intervention Design

WithKirsten Corder, Sonja Klingberg, Esther van Sluijs

Intervention design and subsequent implementation represent an important interchange between observational evidence and trial efficacy. This area between these two rigorously prepared evidence bases is often poorly reported, and is rarely given the gravitas that it deserves in the scientific literature. This chapter summarizes some key considerations when approaching intervention design and suggests various strategies which may help researchers to bridge the gap between observational evidence and assessment of intervention efficacy. As illustrated by the social ecological model, it is important to consider the wider socio-ecological context of behaviors and interventions. Furthermore, in designing evidence-based physical activity interventions, the context also delineates what evidence is available to be applied in the design process. Physical activity promotion through schools may be achieved through the curriculum, but also through the social, policy and physical environments that schools provide.
