Testing Self-Control as a Behavior Change Mechanism to Increase Physical Activity

Participants will wear a Fitbit for 8 weeks to record their daily activity data. The first week of the study will provide a baseline measurement of activity. Across the 8 weeks, participants receive daily reminders to wear their Fitbit. After the baseline week, participants will also receive interventional components that target self-control via the smartphone application MindHike. This intervention should help them achieve their activity goals. The self-control intervention teaches strategies how to potentiate desirable impulses and how to avoid undesirable impulses in daily life.

Participants will wear a Fitbit for 8 weeks to record their daily activity data. The first week of the study will provide a baseline measurement of activity. Participants in this condition receive daily reminders to wear their Fitbit through the MindHike smartphone application. Participants in the control group will be matched with the self-control intervention group for how much contact they have with the app and the researchers.
