Abstract:

Study examining the relative contributions of substance abuse history and violent etiology to the prediction of outcomes for individuals who sustained a traumatic brain injury (TBI) requiring inpatient rehabilitation. Participants were 351 individuals admitted consecutively to a specialized TBI rehabilitation unit. It was found that 80% of persons with injuries from violence-related causes had a history of substance abuse. Substance abuse was found to contribute to the prediction of life satisfaction and productivity, while violent etiology was not a significant contributor to predictive models. The authors conclude that it is necessary to include substance abuse history in all studies of outcomes after TBI, and to increase prevention efforts to limit the effects of such a history.
