Opt-IN: Optimization of Remotely Delivered Intensive Lifestyle Treatment for Obesity
In Brief
A Phase 3 clinical trial evaluating 12 Telephone Coaching Sessions, 24 Telephone Coaching Sessions, and 4 other interventions for Weight Loss. Completed, enrolled 562 participants across 1 site.
Detailed 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.
