title: Field trial of the Global Assessment of Functioning Scale--Modified.
abstract: OBJECTIVE
  A field trial of the Global Assessment of Functioning Scale--Modified was conducted to test its construct validity. A slightly altered form of the scale, the Social and Occupational Functioning Assessment Scale, was used in DSM-IV.
  
  
  METHODS
  Social, occupational, and clinical data on 196 subjects receiving outpatient mental health services were analyzed.
  
  
  RESULTS
  Six significant predictors were found that accounted for 51.75% of the variation in scores on the Global Assessment of Functioning Scale--Modified. Scores were independent of axis I, axis II, and psychoactive substance dependence diagnoses from DSM-III-R.
  
  
  CONCLUSIONS
  The construct validity of the Global Assessment of Functioning Scale--Modified and the Social and Occupational Functioning Assessment Scale is supported by these findings.
