AB  - PURPOSE: The aim of this study was to investigate concurrent validity of the 
      Swedish self-rated 36-item World Health Organization Disability Assessment 
      Schedule (WHODAS) 2.0 by comparison with professional Global Assessment of 
      Functioning (GAF) ratings in psychiatric outpatients. MATERIAL AND METHODS: A 
      cross-sectional convenience sample of 444 patients was recruited from their 
      regular psychiatric outpatient settings. The patients filled out the WHODAS 2.0; 
      their clinicians provided clinical information and performed GAF ratings blinded 
      to the patients' assessments. Analyses of correlations, variance components, and 
      ROC curves were performed to investigate the validity of the WHODAS 2.0 through 
      comparison with the GAF. The variance component analyses included working status, 
      psychosocial problems, number of diagnostic groups, and remission status. GAF 
      ratings were separated as total (GAF-T), symptoms (GAF-S), and functioning 
      (GAF-F). RESULTS: There was significant correlation (p < 0.001) between WHODAS 
      2.0 total and domain scores and GAF-S, GAF-F, and GAF-T ratings. The correlations 
      varied from r = 0.29 to r = 0.48, with the highest being between GAF-F rating and 
      WHODAS 2.0 total score. Repeating the analyses for separate diagnostic groups 
      replicated the findings, though not for psychotic, substance-related, and eating 
      disorders. The WHODAS 2.0 showed good ability to distinguish impaired functioning 
      below a fixed GAF-T cut-off of 70 (area under the curve: 0.74-0.78). The 
      explained variance was lower for the WHODAS 2.0 than for the GAF (38.9% vs. 
      59.2%). CONCLUSIONS: Concurrent validity was found when comparing the Swedish 
      self-administered 36-item version of WHODAS 2.0 with the expert-rated GAF in 
      psychiatric outpatients.
