Overview of applying the RE-AIM framework in evaluating and adapting the Active Plus project.

RE-AIM dimension	Definition	Adaptation for the Active Plus project
Reach	Number and representativeness of individuals willing to participate	Extending the delivery mode to a Web-based version
		Providing additional information to reach both low- and high-socioeconomic status groups
		Providing additional information to reach participants with physical disabilities
Effectiveness	Impact of the intervention on target outcomes	Translating the print-delivered interventions into Web-based interventions
		Adding information to increase intervention effects in the subgroups that were less affected by the original intervention (persons with a normal body mass index and persons aged over 65 years)
		Improving intervention strategies
		Stimulating self-efficacy and strategic planning
		Stimulating intrinsic motivation
		Reinforcing and extending environmental information
Adoption	Proportion and representativeness of settings that adopt the intervention	Translating the print-delivered interventions into Web-based interventions. Response rates to the print-delivered interventions are higher than response rates to the Web-based interventionsa
Implementation	Extent to which the interventions are delivered as intended	a
Maintenance	Extent to which individual participants maintain behavior change long term and the extent to which the intervention is sustained over time within the organizations that deliver the intervention	Improvements made to the original interventions are expected to further increase the effects on physical activity behaviora
