PREVALENCE OF PTSD IN VETERANS

National Vietnam Veterans Readjustment Study

  • The National Vietnams Veterans Readjustment Study (NVRS), conducted between November 1986 and February 1988, comprised interviews of 3,016 American Veterans selected to provide a representative sample of those who served in the armed forces during the Vietnam era.  The estimated lifetime prevalence of PTSD among these Veterans was 30.9% for men and 26.9% for women.  Of Vietnam theatre Veterans, 15.2% of males and 8.1% of females were currently diagnosed with PTSD at the time the study was conducted.

Gulf War Veterans

  • Kang and others conducted a study to estimate the prevalence of PTSD in a population-based sample of 11441 Gulf War Veterans from 1995 to 1997.  PTSD was assessed using the PTSD Checklist rather than interviews, with those scoring 50 or higher considered to have met the criteria for PTSD.  The prevalence of current PTSD in this sample of Gulf War Veterans was 12.1%.  Further, the authors estimated the prevalence of PTSD among the total Gulf War Veteran population to be 10.1%.

Operation Enduring Freedom / Operation Iraqi Freedom

  • In 2008, the RAND Corporation, Center for Military Health Policy Research, published a population-based study that examined the prevalence of PTSD among previously deployed Operation Enduing Freedom and Operation Iraqi Freedom (Afghanistan and Iraq) service members.  PTSD was assessed using the PTSD Checklist, as in the Gulf War Veterans study.  Among the 1,938 participants, the prevalence of current PTSD was 13.8%.
