title: The long-term efficacy of three psychotherapies for anorexia nervosa: a randomized, controlled trial.
abstract: OBJECTIVE
  To evaluate the long-term efficacy of three psychotherapies for anorexia nervosa.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  Potential implications for the timing of interventions to improve treatment response in anorexia nervosa are critically examined.
