Evaluating "Take the Stairs, Wyoming!" Through the RE-AIM Framework: Challenges and Opportunities.

Health promotion delivery systems are increasingly being asked to implement policy, systems, and environmental interventions (PSEs). However, evaluating PSEs is challenging, especially in low-resource community settings. This paper describes the use of RE-AIM to evaluate a physical activity PSE delivered through University of Wyoming Extension and highlights challenges and opportunities in pragmatic, real-world program evaluation. Extension health educators adapted a point-of-decision prompt intervention encouraging stairway use through posters, called Take the Stairs, Wyoming! was assessed through estimates of daily traffic, was assessed through opportunistic interviews, was calculated as the number and proportion of sites that agreed to hang posters, was calculated as the proportion of sites with a poster in place at a 2-weeks follow-up visit, and was assessed through 6-months opportunistic interviews (individual level) and proportion of sites with a poster in place (organizational level). Overall, the posters were widely and most posters were as intended. However, capturing , and was challenging, as health educators found the evaluation burdensome. Therefore, it was difficult to determine if the posters were effective at increasing physical activity levels. Suggestions are provided for capturing , and data in community settings. Future efforts are needed to create evaluation tools to pragmatically measure effectiveness of PSEs on changing behaviors, as well as to prioritize program evaluation in Extension.
