Long Term Outcome of Anorexia Nervosa

Abstract

The long-term outcome (mean follow-up period 5.7 years) for 20 patients with anorexia nervosa was assessed on a comprehensive battery of self-report inventories and a structured clinical interview. Two thirds of the cohort were improved to a clinically significant degree at follow-up, but the majority still showed higher than normal scores on inventories of anorexic symptomatology, social maladjustment, anxiety, and hostility. The remaining one third were unimproved and demonstrated a broad range of impairment including distorted attitudes toward eating, overconcern about body shape, poor social functioning, high levels of anxiety, hostility, depression, and external locus of control. Moderate to strong correlations were found across outcome measures. Longer duration of eating difficulties before presentation was a strong predictor of poor long-term outcome, suggesting a chronic relapsing form of the disorder occurred in a subgroup of patients.
