We used nationally representative survey data to examine the generalizability of this extensive body of research by comparing sociodemographic and clinical characteristics of male veteran veterans health service (VHS) users (n = 491) with veteran non-VHS users (n = 840) and nonveteran (n = 6300) MH service users. VHS users were older, more often reported Black race, and less likely to have private or Medicaid insurance, but had similar prevalence of psychiatric or substance use disorder diagnoses but with a greater prevalence of posttraumatic stress disorder (PTSD). VHS users reported higher rates of medical diagnoses, pain interference, and poorer physical and MH status. These results suggest that VHA MH research may be reasonably generalizable to US mental health service users with caveats regarding age, PTSD diagnosis, pain, and racial distribution.
