Researchers are evaluating a new mobile app designed to help teenagers who have difficulty controlling their eating behaviors and who have higher body weight. This intervention combines cognitive-behavioral treatment with strategies to improve self-regulation for managing unhealthy eating patterns. The study focuses on adolescents with dysregulated eating and elevated weight status, aiming to understand the app's usability and effectiveness in this group. Participants will use the VIBE app for 16 weeks, receiving coaching and support through the app. Before starting the main trial, eligible adolescents and their parents attend a virtual assessment and complete questionnaires and interviews. Participants then complete a test-run week wearing a Fitbit and using a Smartscale to record weight, alongside dietary recalls. Those who engage well continue with the 16-week intervention, including additional app-based skill-building tasks. Throughout the study, participants complete three assessment visits: mid-point at 8 weeks, post-intervention at 16 weeks, and a follow-up 4 months later. These assessments include interviews, weight measurements, Fitbit monitoring, dietary recalls, cognitive tasks, and online surveys, each lasting about 90 to 120 minutes. Researchers will measure usability, acceptability, body mass index percentile, and dysregulated eating behaviors over up to 9 months of participation.
