A Mobile Self-Guided Program for Adults With Binge Eating and Obesity Using the ChangeBite App

What this Trial Is About

Researchers are evaluating the feasibility and usability of a digital intervention called ChangeBite for adults with obesity and binge eating behavior. This open-label, non-randomized pilot study plans to include about 30 participants. The study aims to understand how well participants can engage with this self-guided mobile program that combines evidence-based treatments for obesity and binge eating. All participants will receive the ChangeBite intervention delivered through a smartphone app. The program integrates behavioral weight loss treatment and cognitive behavioral therapies into a personalized, self-guided experience using an artificial conversational agent and adaptive interventions. The study includes a baseline period followed by assessments at 12 and 24 weeks, during which participants will use the app and attend follow-up video calls. Participants will complete self-report scales and semi-structured interviews conducted via video call. The study will track app use frequency and duration through software analytics. Weekly body weight will be recorded by participants submitting timestamped pictures of their scale readings, allowing calculation of Body Mass Index. The research team will measure binge eating episodes and weight changes over three months to assess feasibility and acceptability of the intervention.
