title: Using subtests of the Brain Age Quotient to screen for cognitive deficits among substance abusers.
abstract: The subtests of the Brain Age Quotient, a brief neuropsychological battery, were used to screen for cognitive impairment in a sample of 112 substance abusers. Each of the subtests was scored, using newly developed T scores corrected for age, education, and gender, for which a mean battery score of T less than 40 indicates general cognitive impairment. The chance-corrected agreement in finding cognitive dysfunction between this battery and the Average Impairment Rating T score from the Halstead-Reitan battery was adequate, kappa = .81. This result suggests that, for discerning global cognitive impairment, this relatively brief neurodiagnostic screening device may be an attractive alternative to the more time-consuming Halstead-Reitan battery.
