Abstract We hypothesized that PTSD symptomatology would have an inverse relationship with functional status and vary as a function of sociodemographic variables. Primary care patients ( N = 513) at two VA Medical Centers were randomly selected recruited to participate. After adjustment for other demographic symptom levels significantly related age (younger had more severe symptoms), employment (disabled persons higher levels), war zone experience, clinic location. was inversely mental...
