Objective: To evaluate the long‐term efficacy of three psychotherapies for anorexia nervosa. Method: Participants were women with broadly defined anorexia nervosa who had participated in a RCT comparing specialized psychotherapies (cognitive behavior therapy, CBT, and interpersonal psychotherapy, IPT) with a control condition (specialist supportive clinical management, SSCM), and attended long‐term follow‐up assessment (mean 6.7 years ± 1.2). Results: Forty three of the original sample of 56 women participated in long‐term follow‐up assessment (77%). No significant differences were found on any pre‐selected primary, secondary or tertiary outcome measures among the three psychotherapies at long‐term follow‐up assessment. Significantly different patterns of recovery were identified for the psychotherapies across time on the primary global outcome measure. Although SSCM was associated with a more rapid response than IPT, by follow‐up all three treatments were indistinguishable. Discussion: Potential implications for the timing of interventions to improve treatment response in anorexia nervosa are critically examined. © 2010 by Wiley Periodicals, Inc. Int J Eat Disord 2010
