The Effect of Group-Based Weight-Control Intervention on Adolescent Psychosocial Outcomes: Perceived Peer Rejection, Social Anxiety, and Self-Concept

This article examines the effectiveness of group-based weight-control treatment on adolescent social functioning. Eighty-nine adolescents, who were randomized to group-based cognitive behavioral treatment with aerobic exercise or peer-enhanced adventure therapy, completed measures of social functioning at baseline, end of treatment, and at a 12-month follow up. Results demonstrated significant reductions in adolescent perceptions of peer rejection and social anxiety over time, with no significant demonstrated group differences. Improvements in social functioning were related to increases in self-concept dimensions. Findings demonstrate benefits of group-based weight-control treatment for enhancing adolescent self-perceived social functioning across multiple domains.
