What this trial studies

This randomized controlled trial tests a Theory of Planned Behavior–based, multi-modal digital intervention using AI-driven coaching, interactive platforms, gamified apps, and real-time feedback to change attitudes, subjective norms, and perceived behavioral control among adolescents with overweight or obesity. Adolescents aged 12–18 with BMI at or above the 85th percentile will be randomized to receive the digital intervention or a comparison condition and will provide parental consent. Outcomes include changes in TPB constructs, weight-control intentions, and both healthy and unhealthy weight-control behaviors, with secondary attention to body image and mental health as moderators. The trial is conducted at National Yang Ming Chiao Tung University sites in Taipei and Hsinchu and uses digital monitoring and self-report measures to capture behavior and engagement.
