Prevalence of Mental Health Problems and Functional Impairment Among Active Component and National Guard Soldiers 3 and 12 Months Following Combat in Iraq

Researchers examined the prevalence rates of depression and posttraumatic stress disorder (PTSD), determined the comorbidity of alcohol misuse or aggressive behaviors with depression or PTSD, and compared prevalence rates between Active Component and National Guard Soldiers (N = 13,226). Participants were surveyed at 3- and 12-months postdeployment to Iraq (OIF). In this sample, PTSD prevalence ranged from 6% to 11% and depression prevalence from 5% to 9%.
