title: Cognitive-behavioral group therapy for obsessive-compulsive disorder: a 1-year follow-up.
abstract: OBJECTIVE
  The aim of this study was to evaluate the results of cognitive-behavioral group therapy (CBGT) for obsessive-compulsive disorder (OCD) over a 1-year follow-up period.
  
  
  METHODS
  Forty-two OCD patients, who completed 12 sessions of CBGT, were followed for 1 year. Measures of the severity of symptoms were obtained at the end of the acute treatment and at 3, 6, and 12 months post-treatment using the Yale-Brown obsessive-compulsive scale (Y-BOCS) and the clinical global impression (CGI).
  
  
  RESULTS
  The reduction in the severity of symptoms observed at the end of the treatment was maintained during 1 year (F2,41=1.1; P=0.342). Eleven patients (35.5%) relapsed in the follow-up period. The intensity of improvement (log rank=12.97, GL=1, P=0.0003) and full remission (log rank=6.17; GL=1; P=0.001) were strong predictors for non-relapsing.
  
  
  CONCLUSIONS
  The CBGT is an effective treatment for OCD and its results are maintained for 1 year. However, further long-term randomized controlled trials are needed in order to confirm this finding.
