Adolescence is a crucial developmental stage marked by intensified peer influence, social comparison, and a strong need for social acceptance.
Social anxiety, peer problems, and low prosocial behaviour significantly predict poorer early weight restoration in adolescents with anorexia nervosa.
Adolescence is a crucial developmental stage marked by intensified peer influence, social comparison, and a strong need for social acceptance. These psychosocial changes markedly impact mental health and are closely linked to the onset and progression of eating disorders, particularly anorexia nervosa. Evidence suggests that impaired social cognition, elevated social anxiety, autism-spectrum traits, and peer relationship difficulties frequently co-occur in affected adolescents, complicating both clinical presentation and treatment response. However, the extent to which baseline social functioning predicts recovery outcomes remains insufficiently understood.
This large-scale study investigated whether baseline measures of social anxiety and peer functioning could predict early treatment response, specifically weight restoration within the initial 6 months of treatment in adolescents diagnosed with anorexia nervosa.
This nationwide clinical cohort study included 983 adolescents (aged 12–16 years) receiving treatment from community-based eating disorder services in England, UK. At baseline assessment, volunteers completed standardized psychological tools:
The key outcome ascertained was early weight recovery, defined as attaining ≥85% median body mass index (mBMI), adjusted for age and gender, at 6 months post-assessment. Multiple linear regression analysis evaluated the predictive role of:
Baseline social functioning markedly influenced early recovery outcomes in adolescent anorexia nervosa:
Collectively, these social and interpersonal factors explained 20% of the variance in early weight restoration at 6 months. Higher levels of social anxiety were consistently noted among adolescents who failed to achieve early weight recovery. These effects were independent of age.
Social anxiety, impaired peer relationships, and reduced prosocial behaviour are prominent predictors of poor early treatment response in adolescent anorexia nervosa. This underscores the importance of integrating social functioning assessment and targeted psychosocial interventions into eating disorder treatment programs to improve recovery outcomes.
