title: Long-term efficacy of psychological treatments for binge eating disorder.
abstract: BACKGROUND
  The long-term efficacy of psychological treatments for binge eating disorder remains largely unknown.
  
  
  OBJECTIVE
  To examine the long-term efficacy of out-patient group cognitive-behavioural therapy (CBT) and group interpersonal psychotherapy (IPT) for binge eating disorder and to analyse predictors of long-term non-response.
  
  
  METHODS
  Ninety people with binge eating disorder were assessed 4 years after treatment cessation within a randomised trial (trial registration: NCT01208272).
  
  
  RESULTS
  Participants showed substantial long-term recovery, partial remission, clinically significant improvement and significant reductions in associated psychopathology, despite relapse tendencies in single secondary outcomes. Body mass index remained stable. While the IPT group demonstrated an improvement in eating disorder symptoms over the follow-up period, the CBT group reported a worsening of symptoms, but treatments did not differ at any time point.
  
  
  CONCLUSIONS
  The results document the long-term efficacy of out-patient CBT and IPT for binge eating disorder. Further research is warranted to elucidate the time course and mechanisms of change of these treatments for binge eating disorder.
