Abstract
This study examined predictors and indicators of quality of life in 71 patients with closed-head injury (CHI), 2-4 years postinjury. Predictors included premorbid characteristics and acute injury-related data. Indicators included follow-up data, e.g., neuropsychological functioning. Exploratory canonical correlation analyses demonstrated that the combination of the predictor variable, initial Glasgow Coma Scale score, and indicator variables of neuropsychological data in the areas of motor functioning, memory, and constructional ability were related most strongly to quality of life as reported by the patients. Severity of head injury and motor disability also related strongly to quality of life, based on reports by relatives (n = 68) on the Katz Adjustment Scale (Relatives' Form). These findings suggest that quality of life is adversely affected by increased severity of head injury and greater residual motor deficits. Implications of these findings for treatment and recovery are discussed.
