Combat duty in Iraq and Afghanistan, mental health problems and barriers to care

The current combat operations in Iraq and Afghanistan have involved US military personnel in major ground combat and hazardous security duty. Studies are needed to systematically assess the mental health of members of the armed services who have participated in these operations and to inform policy with regard to the optimal delivery of mental health care to returning veterans. We studied members of 4 US combat infantry units (3 Army units and a Marine Corps unit) using an anonymous survey that was administered to the subjects either before their deployment to Iraq (n=2530) or 3 to 4 months after their return from combat duty in Iraq or Afghanistan (n=3671). The outcomes included major depression, generalized anxiety, and posttraumatic stress disorder (PTSD), which were evaluated on the basis of standardized, self-administered screening instruments. Exposure to combat was significantly greater among those who were deployed to Iraq than among those deployed to Afghanistan. The percentage of study subjects whose responses met the screening criteria for major depression, generalized anxiety, or PTSD was significantly higher after duty in Iraq (15.6% to 17.1%) than after duty in Afghanistan (11.2%) or before deployment to Iraq (9.3%); the largest difference was in the rate of PTSD. Of those whose responses were positive for a mental disorder, only 23% to 40% sought mental health care. Those whose responses were positive for a mental disorder were twice as likely as those whose responses were negative to report concern about possible stigmatization and other barriers to seeking mental health care. This study provides an initial look at the mental health of members of the Army and the Marine Corps who were involved in combat operations in Iraq and Afghanistan. Our findings indicate that among the study groups there was a significant risk of mental health problems and that the subjects reported important barriers to receiving mental health services, particularly the perception of stigma among those most in need of such care. The recent military operations in Iraq and Afghanistan, which have involved the first sustained ground combat undertaken by the United States since the war in Vietnam, raise important questions about the effect of the experience on the mental health of members of the military services who have been deployed there. Research conducted after other military conflicts has shown that deployment stressors and exposure to combat result in considerabl
