TI  - Structural equation modeling of associations among combat exposure, PTSD symptom 
      factors, and Global Assessment of Functioning.

AB  - This study used structural equation modeling (SEM) to evaluate the relative 
      strength of associations between combat exposure, four posttraumatic stress 
      disorder (PTSD) symptom factors, and functional impairment as indexed by Global 
      Assessment of Functioning (GAF) scores in a sample of 315 veterans assessed at a 
      Department of Veterans Affairs PTSD clinic. Results showed that the association 
      between combat exposure and GAF scores was fully mediated by PTSD severity. The 
      best-fitting model included direct paths from combat exposure to reexperiencing 
      symptoms and from avoidance and numbing symptoms to GAF. However, only 17% of 
      variance in GAF was accounted for by PTSD. The results raise concern about the 
      use of the GAF score as a benchmark for quantifying combat PTSD-related 
      functional impairment.
