Neuropsychological Prediction of Psychosocial Outcome After Traumatic Brain Injury

Abstract

The ability of neuropsychological tests to predict later psychosocial outcome on the Community Integration Questionnaire (CIQ; WiIler, Rosenthal, Kreutzer, Gordon, & Rempel, 1993) was examined. A previous investigation by Millis, Rosenthal, and Lourie (1994) found that the Trail Making Test (TMT; Lezak, 1995) and the Rey Auditory Verbal Learning Test (RAVLT; Lezak, 1995) were related to performance on the CIQ at 1 year postinjury. The RAVLT and the TMT Parts A and B (TMT-A, TMT-B) in conjunction with age at time of injury significantly predicted psychosocial outcome as measured by individual self-report. When self-reported functioning was examined by domain, these variables significantly predicted home and social adaptation. These variables were applied to significant others' reports of community integration, where age and the TMT remained significant predictors of psychosocial outcome. These results underscore the utility of neuropsychological measures in the prediction of later community integration after traumatic brain injury.
