Physical Activity
Conditions
Brief summary
The purpose of this study is to evaluate the effect of adding a team competition comprised of members of existing social networks to a technology-delivered program for enhancing physical activity among insufficiently active adults.
Detailed description
This 3-month randomized controlled trial is designed to investigate the efficacy and feasibility of a novel, technology-oriented physical activity intervention characterized by existing social networks and a team competition. Participants will be recruited via emails, fliers, and word of mouth. They will be randomized to a technology-mediated physical activity treatment (TECH) or a treatment which receives an identical intervention as TECH plus a study designed team competition for physical activity promotion (TECH+COMP).
Interventions
Participants will receive a theory-based physical activity program. They will enroll in the study as part of a self-selected group of 3-8 individuals. They will be provided with a personal step goal and Fitbit Alta HR for self-monitoring physical activity. They will also have access to a study website that will be accessible across conventional and mobile platforms. They will be asked to visit the website each week to receive behavior change information and guidance. Device: Fitbit Alta HR
Participants will receive the same intervention components as the TECH group, as well as a team competition. The competition will be based on the following two aspects: total daily steps accumulated relative to group size and total number of points retained for achieving weekly physical activity challenges. Device: Fitbit Alta HR
