The future of physical activity behavior change research: what is needed to improve translation of research into health promotion practice?

There is a gap between physical activity intervention research and the delivery of evidence-based programs in practice. We describe individual and setting level factors important for translation that moderate the impact of interventions and often are not reported in the literature. The Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework provides a useful way of organizing and reporting these factors.
