Study Overview
Brief Summary
The present study is a non-inferiority trial comparing the efficacy of a lifestyle intervention delivered entirely via an online social network to a traditional lifestyle intervention delivered via group meetings.
Detailed Description
Lifestyle interventions have had established efficacy for over a decade but are still not widely disseminated, largely due to high cost and patient and provider burden. Online social networks are an alternative way to deliver lifestyle counseling and delivery via this modality may virtually eliminate patient visits, the main source of cost and burden in traditional modalities. Interactions in online social networks are frequent, brief, and asynchronous because users login to their online communities during downtime during work and leisure time, or when they simply feel a need for social connection. As such, social media becomes embedded into people's daily lives. This provides an opportunity to embed health behavior change programming into people's daily lives. Thus far in the literature, existing online social networks have been used as component of web- or mobile app-based lifestyle interventions but not as the primary modality for intervention delivery. The purpose of this work is to conduct a non-inferiority trial to compare a lifestyle intervention delivered entirely via private groups on the online social network Twitter to a traditional in-person group-based lifestyle intervention. Using a randomized trial (N=328), investigators will test whether a lifestyle intervention delivered via an online social network (Get Social condition) will result in a mean percent weight loss at 12 months that is not appreciably worse than the gold-standard in-person group-based lifestyle intervention (Traditional condition), i.e., the social network arm will not lose on average 2% less than the in-person arm. Secondary non-inferiority outcomes include weight loss at 12 months, and dietary intake and physical activity at 12-months. Investigators hypothesize that the Get Social condition will be less expensive than the Traditional condition. To understand for whom an online social network modality is most suited, investigators will test predictors of weight loss in the Get Social condition including engagement, age, sociability, neuroticism, openness, and smartphone and social network use. Investigators hypothesize that people who are younger, more sociable, engage more on the social network, higher in neuroticism/openness, and heavier overall smartphone and social network users will lose more weight in the Get Social condition. Findings from this study may support an intervention delivery modality that is more conducive to settings like worksites, health plans, and clinics that serve large populations but have limited space, staffing, and resources for traditional in person interventions.

Arms & Interventions
Get Social
Get Social participants will receive a weight loss intervention in a "protected" Twitter group. The intervention content will be structured to deliver in an online context. The online coaches will post daily content, respond to questions, address concerns, and encourage engagement. The weight loss intervention is based on the Diabetes Prevention Program (DPP), an evidence-based weight loss program focused on lifestyle changes. The goals for the intervention are 175 minutes of moderate physical activity per week and an overall weight loss of 7%. Each participant will get an individualized calorie goal that would facilitate a 1-2 lbs. weight loss weekly. Participants will also be encouraged to use an app such as MyFitnessPal to track daily diet.
