Association Between Number of Deployments to Iraq and Mental Health Screening Outcomes in US Army Soldiers

Retrospective data were used to determine the association between multiple deployments to Iraq and post-deployment mental health problems (e.g., posttraumatic stress disorder [PTSD], depression, anxiety), as identified by mental health screening outcomes for U.S. Army soldiers with one or two deployments to Iraq. Multiple deployments were associated with post-deployment PTSD.
