Psychosocial and health correlates of types of traumatic event exposures among U.S. military personnel

Abstract

The prevalence of lifetime exposure to violence, natural disaster, or major accidents involving injuries or fatalities was examined in the largest population-based epidemiologic survey of U.S. military personnel to date. The psychosocial and health effects of types of exposure experience (witness only, victim/survivor, relief worker), gender differences, and social support were also evaluated. Over 15,000 active duty U.S. military personnel from stratified random samples of active duty U.S. personnel from all services responded to either mail questionnaires and/or worksite surveys. The lifetime exposure to one or more traumatic events was 65%; the most prevalent trauma for men was witnessing a major accident, and for women, witnessing a natural disaster. Victims of any traumatic event were at twice the risk of having two or more physical and mental health problems than nonexposed controls. Health outcomes of trauma exposure vary by type of traumatic event: type of exposure experience, rank, and gender.
