Evaluating Whether Charity Incentives Motive Cancer Survivors to Increase Physical Activity

California Polytechnic State University-San Luis Obispo51 enrolled

Overview

The investigators propose to examine whether linking daily activity with charity-based incentives motivates cancer survivors to initiate and maintain physical activity. Linking daily physical activity goals with a cancer specific charity incentive may provide a uniquely salient motivator that promotes increased physical activity among cancer survivors. The investigators will examine whether using activity monitors in combination with charitable incentives leads to greater increases in physical activity compared to activity monitors alone. Target participants includes cancer survivors who are not already active. Physical activity (e.g., steps per day, time in moderate-intensity activity) will be examined at baseline and following a 12-week intervention period using an activPAL accelerometer. After the baseline assessment, both groups will receive a fitbit monitor and informational material designed to increase physical activity. Participants in the fitbit+charity group will have donations made in their name to a cancer charity if they meet daily step goals. Physical activity levels will be monitored using the fitbit device for 6-weeks following the formal intervention period.

The study is a Randomized Controlled Trial (RCT) of a 12-week physical activity intervention. Fifty cancer survivors will be recruited and allocated to one of two research arms: Fitbit+Only Group or Fitbit+Charity Incentives Group. Participants in both intervention arms will be asked to track their physical activities using Fitbit One, an activity monitor that monitors steps and physical activity and will receive basic educational materials about increasing physical activity. Those in the Fitbit+charity incentives Group will raise money for cancer charities if they meet weekly step targets. The key outcome variable of the RCT is steps as measured by an activPAL accelerometer. Data will be collected at baseline and 12-weeks. Fitbit data will also be collected for the duration of the 12-week intervention and for 6-weeks following the end of the intervention period to have an initial examination of behavior change maintenance (total 18-weeks).

ExperimentalBEHAVIORAL

Participants will receive a fitbit and lifestyle counseling to increase steps. Weekly newsletter for first 6 weeks, bi-weekly for remaining weeks with behavioral content designed to increase physical activity (e.g., barriers, SMART goals). They will also receive a donation to a cancer charity of their choice if they meet daily step goals.
