Objective: Research has shown significant rates of comorbidity among posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and pain in prior era veterans but less is known about these disorders in Iraq and Afghanistan war era veterans. This study seeks to extend previous work by evaluating the association among PTSD, MDD, and pain (back, muscle, and headache pain) in this cohort.
Method: A sample of 1,614 veterans, recruited from 2005 to 2010, completed a structured clinical interview and questionnaires assessing trauma experiences, PTSD symptoms, depressive symptoms, and pain endorsement.
