TI  - Generalizability studies of the Global Assessment of Functioning-Split version.
PG  - 88-94
AB  - OBJECTIVE: The study aimed to use the Generalizability Theory to investigate the 
      reliability and precision of the split version of the Global Assessment of 
      Functioning (GAF). MATERIALS: Six case vignettes were assessed by 2 samples; one 
      by 19 experienced and independent raters and another by 58 experienced raters 
      from 8 different day-treatment units, evaluating both symptom and function scores 
      of GAF. METHODS: Generalizability studies were conducted to disentangle relevant 
      variance components accounting for error variance in GAF scores. Furthermore, 
      decision studies were conducted to estimate the reliability of different 
      measurement designs, as well as precision in terms of error tolerance ratio. 
      RESULTS: Both symptom and function scores of GAF were found to be highly 
      generalizable, and a measurement design of 2 raters per subject was found to be 
      most efficient with respect to reliability, precision, and use of resources. 
      CONCLUSION: Both symptom and function scores of GAF seem highly consistent across 
      experienced raters.
