Peer Coaching for Physical Activity Promotion Among Breast Cancer Survivors: Adapting an Efficacious Intervention to Prepare for Implementation

This is a 3-month physical activity intervention aimed to increase moderate-intensity activity among previously inactive breast cancer survivors. Participants will be eligible if they are not currently active, and have recently been diagnosed with breast cancer. Upon eligibility, participants will be randomized into one of two groups. The intervention group will receive weekly guidance from a peer coach to increase their activity throughout the three month intervention. The control group will be encouraged to self-monitor their physical activity throughout the three month intervention. Both groups will receive a Fitbit. Peer coaches will be trained to deliver the physical activity program using a web-based platform; all calls will be virtual. Participants will be assessed before and after the intervention.
