Post-traumatic stress disorder symptom severity in service members returning from Iraq and Afghanistan with different types of injuries.

Introduction: Risk for post-traumatic stress disorder (PTSD) varies in part due to the nature of the traumatic event involved. Both injury and return from combat pose high risk of PTSD symptoms. How different injuries may predispose towards PTSD is less well understood.

Insomnia is the most commonly reported symptom and predicts other symptoms of post-traumatic stress disorder in U.S. service members returning from military deployments.

This study retrospectively reviewed records from current members of the U.S. military who had completed the PTSD Checklist (PCL) at 0 and 3-months after returning from deployments.
