简要总结
The goal of the study is to examine long term sustained weight loss digital intervention in a diverse cohort of adults with overweight/obesity. The intervention includes social gaming (using game-like elements in nongame contexts to promote supportive social interactions and openness to positive behavioral influences) to reward behaviors, such as self-monitoring and social support.
Investigators will accomplish objectives and test hypotheses by following two specific primary aims:
- Determine if the intervention plus gaming produces significantly more weight loss at 12 months than the same intervention without gaming among 240 adults with overweight or obesity and ≥3 T2DM risk factors.
- Examine the differences in social support provision and receipt between groups at 12 months.
详细描述
This is a 1-year behavioral intervention with standardized behavioral content that reinforces self-monitoring behavior delivered via twice-weekly podcasts, tips of the day, weight, physical activity and diet daily tracking. The mLife App will also encourage and facilitate social support among participants (to both groups).
Participants will be randomized to one of two groups: 1) a gamified mLIFE app (n=120) or 2) regular mLIFE app (n=120). Participants will attend a study orientation, complete all baseline measures, be randomized, and then attend a training session for their group. In addition, participants will complete assessment at 6 and 12 months.
