Rapid cycle adaptation of a classroom-based intervention to promote equity in access to youth physical activity.

Our objective was to systematically adapt Interrupting Prolonged sitting with ACTivity (InPACT), a classroom-based physical activity intervention, for home delivery to equitably increase access to structured youth physical activity opportunities during the COVID-19 pandemic. Key steps in the rapid-cycle research adaptation process included: (Step 1) identifying partner organizations; (Steps 2 and 3) engaging in problem and knowledge exploration to examine the problem from different perspectives; (Steps 4 and 5) initiating solution development and testing by selecting an intervention and adapting the format and content for home delivery. Using Rapid RE-AIM to guide online assessment and refinement of InPACT at Home; and (Step 6) utilizing dissemination strategies to extend the reach of the program. Core elements of the InPACT program that were retained included: the use of exercise videos, maintenance of the intervention dose, and teacher-led physical activities. Key adaptations included: utilization of physical education specialists to develop the exercise videos, incorporation of health messaging in videos, and utilization of dissemination strategies (intervention website) to reach K-12 students across the state. Intervention website reach included all 83 counties in Michigan, but goals were not met for website pageviews (5,147; 85% of goal) and video view duration (7 min 19 sec; 37% of goal). Accordingly, dissemination was expanded to include public television broadcasting (monthly viewers: 500,000) and videos were shortened to 8 minutes. Dissemination and implementation science frameworks guided the rapid adaptation of an existing intervention, InPACT, to equitably increase access to structured youth physical activity opportunities at home during the pandemic. © Society of Behavioral Medicine 2022.
