The co-occurrence of posttraumatic stress disorder symptoms and pain: Is depression a mediator?

Abstract

Although recent studies suggest that posttraumatic stress disorder (PTSD) symptoms and pain may be related, the possible mediational role of depression in this relationship has not been examined. This study sought to examine this question in a sample of 130 male veterans seeking assessment or treatment for deployment-related PTSD. Results suggest that PTSD and pain are moderately related (r = .29) but that this relationship is fully mediated by depression. Our findings have important clinical implications: Treatment of PTSD and pain in veteran populations should include careful assessment and regular monitoring of depression. © 2006 International Society for Traumatic Stress Studies.
