Abstract: The conflicts in Iraq and Afghanistan have continued to provide unique challenges for military personnel and researchers alike. Of note is the increase in literature linking posttraumatic stress disorder with the exposure of service personnel to improvised explosive devices or road-side bombs. This study utilized a sample of 81 combat veterans (N = 81) to evaluate the connections between close blast exposure from roadside bombs, distance from said device, and multiple exposure on post-traumatic stress disorder, while controlling for various other variables. This analysis was undertaken using a hierarchical linear regression. The results indicated that traumatic brain injury was the single most significant predictor of post-traumatic stress disorder, above and beyond all other factors. Additionally, it was found that close blast exposure, multiple blast exposure, and distance from the blast were all significantly correlated with traumatic brain injury and post-traumatic stress disorder, but not significantly after controlling for traumatic brain injury
