OBJECTIVE: This study uses data from a multisite randomized clinical trial to study the role of perfectionism in family-based treatment (FBT) for adolescent anorexia nervosa (AN). The main aim is to examine the role of baseline perfectionism in treatment response.
METHOD: Adolescents (N = 158; ages 12-18; 89.2% female) and their families were randomized to receive either FBT or systemic family treatment for AN. Eating disorder (ED) pathology, obsessive-compulsive symptoms, and perfectionism were assessed at baseline, end of treatment, and 6- and 12-month follow-up. Linear regression analyses were used to test whether perfectionism and obsessive-compulsive symptoms at baseline predict ED pathology at all timepoints. An independent samples t test was used to test whether there was a significant difference in the change in perfectionism in either treatment group.
RESULTS: Baseline maladaptive perfectionism significantly predicted ED pathology but not ideal body weight at all timepoints. The model that included obsessive-compulsive symptoms also predicted ED pathology at all timepoints except 12-month follow-up. Perfectionism scores did not change during treatment regardless of treatment type.
DISCUSSION: Baseline perfectionism predicted treatment response in this study. Interventions might target perfectionism to improve treatment response in AN.
