简要总结
The purpose of this study is to evaluate whether a social support-enhanced, technology-based, behavioral weight control intervention can improve weight loss over existing best practices.
详细描述
This 4-month randomized controlled trial is designed to investigate the short-term efficacy and feasibility of a novel, social support-enhanced behavioral weight control intervention. Participants will be recruited via email listservs, fliers, and word of mouth. They will be randomized to a standard behavioral weight control treatment (SBT) or a social support-enhanced behavioral weight control treatment which receives the same intervention as SBT plus social support resources (specifically, additional self-monitoring technologies) for weight loss.

研究组 & 干预措施
Standard
Participants will receive an evidence-based behavioral weight control program focused on physical activity and reducing caloric intake. They will be provided with a Fitbit Zip and digital body weight scale for self-monitoring of physical activity and body weight, respectively. They will track caloric intake via the MyFitnessPal smartphone application. They will have access to a study website and attend weekly, in-person group counseling sessions.
