What is being tested?
The study tests an intervention aimed at reducing the negative effects of WBI while participating in an established adolescent weight management program. Success will be measured by how feasible and acceptable participants find this combined approach after the program ends.See study design
What are the potential side effects?
Since this trial involves behavioral interventions, there may not be physical side effects like with medication. However, participants might experience emotional discomfort or stress as they confront issues related to weight bias.

Experimental Treatment
Group I: WBI+BWMExperimental Treatment2 Interventions
WBI+BWM will be a multicomponent behavioral weight loss intervention designed to address both weight bias internalization and weight status in adolescents. The first four sessions of the intervention will be focused on targeted WBI/weight stigma content, followed by 16 sessions addressing both weight stigma/WBI and evidence-based weight management strategies. Weekly meetings are scheduled for 75 minutes and are facilitated by a behavioral expert (e.g., PhD in clinical psychology). Caregivers attend 4 of the 20 weekly groups with their teens.
