Detailed description

The goal of this K23 aim is to examine the acceptability and feasibility of the 8-week PA4Health intervention compared to a general wellness text program with 3 assessments (baseline, post-intervention \[8 weeks\] and 6 months). Participants will complete a single counseling session prior to starting the program. They complete an objective measure of physical activity by wearing an accelerometer for one week at each assessment time point. During the intervention, they will provided with a Fitbit wrist tracker, that will be synchronized to the app, to be worn during the 8-week intervention. Participants will be able to set goals for physical activity as well as monitor their progress toward achieving their goals. Following the trial, they will complete self-reports survey as well as objective measures of physical activity. They will also complete a single qualitative interview to assess their experience with the intervention and to provide feedback for modification.
