Abstract: History of posttraumatic stress disorder (PTSD) or traumatic brain injury (TBI) has been found to increase risk of suicidal behavior. The association between suicide attempt history among veterans with PTSD and/or TBI was explored. Cases (N = 81) and 2:1 matched controls (N = 160) were randomly selected from a Veterans Affairs Medical Center clinical database. PTSD history was associated with an increased risk for a suicide attempt (OR = 2.8; 95% CI: 1.5, 5.1). This increased risk was present for those with and without a history of TBI. Results support incorporating PTSD history when assessing suicide risk among veterans with and without TBI.
