Objective: To identify personality features predicting early and late outcome after traumatic brain injury (TBI). Design: Multiple regression analyses of data from an inception cohort. Participants: Sixty-nine persons with moderate to severe TBI and significant others (SOs). Outcome Measures: Rasch measure of supervision, independent living, and work (Participation and Independence Measure) at hospital discharge and at 1-year follow-up. Predictor Variables: Duration of posttraumatic amnesia (PTA) and NEO Personality Inventory-Revised completed by participants and SOs to describe participant's preinjury personality. Results: Overall personality variables were within normal limits. Only self-reported Neuroticism, specifically Depression, added significantly to PTA in predicting early outcome. Conclusions: Although self-reported depression negatively affects TBI outcome, other personality features reported by people with TBI and SOs during early recovery are normal and do not affect outcome.
