简要总结
The purpose of this initial pilot and feasibility study is to test different digital, behavioral weight loss approaches, with or without human support, using a sequential, multiple assignment, randomized trial (SMART) design. All participants in this pilot trial will receive a 3-month mobile health (mHealth) program. The dose of human support will vary by first- and second-line randomizations. The feasibility, acceptability, and preliminary outcomes for each of the treatment sequences will be assessed.
详细描述
Ninety-nine adults, ages 18-65, with overweight or obesity, will be randomized in total. All participants will receive an mHealth program (App) for program duration that includes activity tracking with a Fitbit, weight tracking with a smart scale, and an app for diet tracking. At baseline, participants will be randomized to either a a) Fully Automated Kick-Off, or b) Human-Enhanced Kick-Off. "Early responders" will continue with to use App, alone. After 4 weeks, "early non-responders" in both arms will be re-randomized once to one of two augmented interventions with human support: Counseling or Check-In. Assessments will occur at baseline, 1 week, 4 weeks, and 3 months to explore feasibility, acceptability, and preliminary outcomes (weight, self-monitoring adherence, behavioral goal adherence).

结局指标
主要结局
Feasibility- Rate of early nonresponse
时间窗: 4 weeks
The rate of early response will be calculated as the number of individuals deemed "early responders" divided by the total number of participants randomized.
Feasibility- Percentage of participants with missing data at 4 weeks
时间窗: 4 weeks
The percentage of participants with missing data at 4 weeks will be calculated as the number of participants who do not complete the 4-week weight assessment divided by the total number of participants randomized.
