Objective: The authors assessed the effectiveness of a systematic method of pre-deployment mental health screening to determine whether screening decreased negative outcomes during deployment in Iraq's combat setting.

Method: Primary care providers performed directed mental health screenings during standard predeployment medical screening. If indicated, on-site mental health providers assessed occupational functioning with unit leaders and coordinated in-theater care for those cleared for deployment. Mental health-related clinical encounters and evacuations during the first 6 months of deployment in 2007 were compared for 10,678 soldiers from three screened combat brigades and 10,353 soldiers from three comparable unscreened combat brigades.

Results: Of 10,678 soldiers screened, 819 (7.7%, 95% confidence interval [CI]=7.2–8.2) received further mental health evaluation; of these, 74 (9.0%, 95% CI=7.1–11.0) were not cleared to deploy and 96 (11.7%, 95% CI=9.5–13.9) were deployed with additional requirements. After 6 months, soldiers in screened brigades had significantly lower rates of clinical contacts than did those in unscreened brigades for suicidal ideation (0.4%, 95% CI=0.3–0.5, compared with 0.9%, 95% CI=0.7–1.1), for combat stress (15.7%, 95% CI=15.0–16.4, compared with 22.0%, 95% CI=21.2–22.8), and for psychiatric disorders (2.9%, 95% CI=2.6–3.2, compared with 13.2%, 95% CI=12.5–13.8), as well as lower rates of occupational impairment (0.6%, 95% CI=0.4–0.7, compared with 1.8%, 95% CI=1.5–2.1) and air evacuation for behavioral health reasons (0.1%, 95% CI=0.1–0.2, compared with 0.3%, 95% CI=0.2–0.4).

Conclusions: Predeployment mental health screening was associated with significant reductions in occupationally impairing mental health problems, medical evacuations from Iraq for mental health reasons, and suicidal ideation. This pre-deployment screening process provides a feasible system for screening soldiers and coordinating mental health support during deployment.
