The ADAPT Trial: Adapting Evidence-Based Obesity Interventions in Community Settings

In Aim 1, the investigators will conduct a community readiness assessment for COACH in 50 community centers serving rural, minority, and low-income families in middle TN. In 25 randomly selected community centers, the investigators will use a systematic process to adapt the intervention protocol based on the assessment results, while maintaining fidelity to COACH's core components. In Aim 2, in a cluster-randomized trial, the investigators will test the comparative effectiveness of each implementation strategy (adaptation vs. original program) on the implementation outcomes of reach, adoption, implementation, and maintenance. In Aim 3, the investigators will test the comparative effectiveness of the adapted and original intervention.

This research is innovative because it uses adaptation science as a potential solution to reduce health disparities in childhood obesity. By testing this intervention in a community resource available to 230 million Americans (community centers), the investigators aim to create a scalable obesity intervention that could be implemented in traditionally underserved populations across the country. This study will also develop and test a theory-based process for adapting behavioral interventions for both obesity and other health outcomes among diverse rural and urban communities.
