Use of demographic variables to predict overall level of performance on the Halstead-Reitan Battery.

Developed and cross-validated an equation that uses demographic variables (sex, age, education, race, occupational categories) to predict average level of performance on the Halstead-Reitan Neuropsychological Test Battery by using a sample of 491 15–81 yr old neurologically normal Ss (mean WAIS IQ 112.8). Regression analysis predicted 65% of the variance in the Average Impairment Rating (59% in cross-validation). It is concluded that demographic variables are useful in providing a context for evaluation of cognitive functioning in Ss with known or suspected brain disorders.
