Neurological, cognitive and attributional predictors of posttraumatic stress symptoms after traumatic brain injury

We investigated the relationship between the reporting of symptoms of posttraumatic stress disorder (PTSD) in a community sample of 66 survivors of severe traumatic brain injury (TBI) and measures of injury severity, memory, insight, and index-event attributions. Correlational analyses revealed that reporting of PTSD symptoms was related to level of insight and not associated with the severity of survivors' injury, educational background, premorbid or current IQ, or memory impairment. The severity of PTSD symptoms was also associated with external attributions to others of causality for the event.
