Adaptive Goals and Interventions for Lifestyle Enhancement
Optimization of a mHealth Behavioral Weight Loss Intervention for Young Adults
Source: ClinicalTrials.gov · Last updated 20 Jul 2025
Brief summary (registry, in English)
Mobile obesity interventions have the potential to reach a diverse population in need; however, while effective, have not resulted in weight losses obtained in in-person interventions. Newer digital approaches called Just-in-Time Adaptive Interventions (JITAI) that offer adaptive, personalized feedback 'when needed' and in 'real time' offer an opportunity to use digital health tools "just in time". This study seeks to identify the optimal components of a comprehensive weight loss JITAI that results in weight losses that meet or exceed those in existing remotely delivered interventions.
