Columbia Moves Physical Activity

Evaluating Columbia Moves: A Social Network Approach Using a Team Competition and Technology to Increase Physical Activity

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.

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).

Inclusion Criteria:

• Insufficiently active as determined by a one-week, accelerometer-based physical activity measurement
• Body mass index (BMI) between 25 kg/m2 and 55 kg/m2
• Between ages 18 and 65 years
• Access to computer with Internet connection
• Smartphone ownership (Android or iOS)
• Willing to be randomized to either one of the two study groups
• Part of a self-selected team of 3-8 eligible individuals
• Members of the same household cannot be part of separate groups
• Able to walk at least 1/4 mile without stopping

Exclusion Criteria:

• Currently lactating, pregnant, or planning to become pregnant during the length of the study
• Diagnosed with type 1 or type 2 diabetes
• Medical or physical contraindications or limitations for engaging in physical activity
• History of major medical or psychiatric conditions
• Currently participating in a physical activity program
