Brief Summary

The overall goal of the Developing Real Incentives and Volition for Exercise (DRIVE) Project is to evaluate whether matching an intervention to individual differences in motivation (high autonomous vs high controlled) is a feasible strategy for engaging African American women in greater total physical activity (PA). The DRIVE Project will develop and evaluate two novel interventions: 1) a challenge-focused program that targets greater PA enjoyment, PA valuation, and relatedness through team-based activities, behavioral skills, and a positive social climate; and 2) a rewards-focused program that targets greater PA competency and relatedness through financial incentives, behavioral skills, and structured social support. To this end, the investigators will be implementing a randomized pilot study at a community center. It is hypothesized that participants who receive an intervention that is matched to their motivation for PA initiation (High Autonomous \& Challenge-Focused; High Controlled \& Rewards-Focused) will demonstrate greater improvements from baseline to post- in total physical activity than those who receive an unmatched intervention (High Autonomous \& Rewards-Focused; High Controlled \& Challenge-Focused). The DRIVE project will provide proof-of-concept for the feasibility and usefulness of developing motivationally-targeted intervention programs for engaging African American women in greater PA.

Outcome Measures

Primary Outcomes (1)

• Change in total physical activity

  Average minutes of total physical activity (PA) per day; Objective assessments of total PA will be obtained with omni- directional accelerometers. Participants will wear the monitor affixed by an elastic belt over the right hip for 7 consecutive days during baseline and post-intervention (2 months). Consistent with previous studies, a valid day will consist of 10 hours of wear time, and 60 consecutive zeros will indicate non-wear with the allowance of up to 2 minutes under the count threshold for sedentary activity. Data reduction will use previously established accelerometer cut-points (Light PA: 100-1534, MVPA \> = 1535), which will be summed to calculate total PA.

  Baseline to 2 months

Secondary Outcomes (1)

• Change in moderate to vigorous physical activity

Other Outcomes (2)

Interventions

Challenge-Focused Program BEHAVIORAL

Participants receiving the Challenge-Focused intervention will complete an 8-week group program. Group sessions meet once per week for 90 minutes and include three components - discussion-based health promotion initiative, team-based physical activity games/activities, and team-based goal-setting and behavioral skills training. Among participants with high autonomous motivation, those receiving the Challenge-focused intervention are expected to show greater improvement from baseline to post- in total PA than those receiving the Rewards-Focused intervention.

Challenge-Focused Program

Rewards-Focused Program BEHAVIORAL

Participants receiving the Rewards-Focused intervention will complete an 8-week group program. Group sessions meet once per week for 90 minutes and include three components - discussion-based health promotion initiative, group-based walking program, and individual-based goal-setting and behavioral skills training with partner-based contracts and financial incentives. Among participants with high controlled motivation, those receiving the Rewards-focused intervention are expected to show greater improvement from baseline to post- in total PA than those receiving the Challenge-Focused intervention.

Model Details: The randomized pilot study compares the effects of receiving a matched (Autonomous \& Challenge-Focused; Controlled \& Rewards-Focused) versus an non-matched (Autonomous \& Rewards-Focused; Controlled \& Challenge -Focused) group-based PA intervention program over an 8-week time period. Randomization to the Rewards- or Challenge-focused intervention is stratified by degree of autonomous motivation (low, medium, high). A total of 150 African American women will be randomly assigned to either receive the Rewards- or the Challenge-focused intervention.
