#### Abstract

The serious nature of the psychosocial maladjustment of many traumatic brain-injured (TBI) patients has led researchers to attempt to predict the eventual level of recovery of these patients. The ability to predict the psychosocial adjustment would be invaluable for several reasons: it would allow professionals to provide patients with more accurate information concerning their likely level of recovery and also bring their family's expectations to realistic levels; it could also help professionals identify sooner patients in greatest need of counseling. Numerous studies have demonstrated the predictive superiority of neuropsychological variables over that of the initial indices of severity such as coma length and PTA duration. A sample of 50 TBI patients was followed-up $2{1\over2}$ years postinjury. The overall results clearly documented the extent of the psychosocial maladjustment experienced by the majority of TBI patients. Canonical correlations were used to determine the relative contribution of neuropsychological data obtained at 6 months postinjury, indices of severity of trauma, age, sex, education, and skull fracture with respect to long-term psychosocial adjustment. The results revealed that although severity of injury and age remained strong predictors of later adjustment, neuropsychological impairment, when expressed in terms of an Average Impairment Rating, surpassed all other variables in terms of its predictive power.Dept. of Psychology.
