Prediction of employment outcome one to three years following traumatic brain injury (TBI).

The current study investigated the relationship between age, education (EDUC), pre-injury productivity (PIP), Glasgow Coma Scale score, and a functional rating score at admittance and discharge from rehabilitation (Disability Rating Scale [DRS]) to employment status at one to three years following traumatic brain injury. EDUC, admit DRS, discharge DRS, and PIP all correlated significantly with follow-up employment status, 0.29, -0.32, -0.36, and 0.25 respectively. All possible combinations were then evaluated by Mallow's Cp statistic. The best fitting model was then used in a discriminant function analysis. The discriminant function correctly classified 84% of the employed subjects, 66% of the unemployed, and 75% across both groups. The current results compare favourably with those obtained in previous studies.
