What this trial studies

This clinical trial aims to evaluate the effectiveness of an acceptance-based healthy lifestyle intervention compared to a traditional health education program for adolescent girls aged 14-19 who are overweight or obese. Participants will engage in a 6-month program that includes both in-person and remote group sessions, focusing on self-regulation skills, mindfulness, and adaptive responses to unhealthy cues. The study will assess various health metrics, including weight, body composition, and psychological factors, to determine the intervention's impact on weight loss and overall health. The trial specifically targets diverse populations, including those from racial and ethnic minority backgrounds.

Why it matters

Potential benefit: If successful, this intervention could lead to significant weight loss and improved health outcomes for adolescent girls struggling with obesity.

How similar studies have gone: Previous studies have shown acceptance-based therapy to be effective in adult populations, but this approach tailored for adolescents is novel and untested.
