NCT01814072

Brief Summary

The overall objective of the proposed research is to use an innovative methodological framework, the Multiphase Optimization Strategy (MOST), to design, for the first time, an optimized, scalable version of a technology-supported intensive lifestyle intervention (INLI) for obesity. MOST involves highly efficient randomized experimentation to assess the effects of individual treatment components, and thereby identify which components and component levels make important contributions to the overall program effect on weight loss. This information then guides assembly of an optimized treatment package that achieves target outcomes with least resource consumption and participant burden. Because the intervention strategies being tested minimize in-person coaching and leverage technology that participants already own, the new optimized intervention, to be called Opt-IN, will be more scalable than traditional INLIs. Opt-IN will thus enjoy greatly increased reach, and enable significant progress in the fight against obesity.

Outcome Measures

Primary Outcomes (2)

  • Weight Change (kg) From Baseline to Month 6, Main Effect of Time

    Estimated mean change from Baseline to Month 6 were obtained from a linear mixed models analysis of variance to account for missing data. All randomized participants were utilized in the model (ITT analysis).

    From Baseline to Month 6

  • Weight Change (kg) From Baseline to Month 6, Time by Factor Interaction

    Estimated mean change from Baseline to Month 6 were obtained from a linear mixed models analysis of variance to account for missing data. All randomized participants were utilized in the model (ITT analysis). This outcome measure is reported as an additional effect beyond that of Outcome Measure 1 (each component has it's own weight loss effect that is above and beyond the weight change calculated in the Outcome Measure 1 analyses).
