POTENTIAL IMPACT OF AGE-CORRECTED AND EDUCATION-CORRECTED SCORES ON HRNB SCORE PATTERNS IN PARTICIPANTS WITH FOCAL BRAIN INJURY

Heaton, Grant, and Matthews (1991) presented an alternate scoring syst em for the Halstead-Reitan Neuropsychological Battery (HRNB) wing age- , education-, and gender-corrected T scores to replace the raw score s ystem traditionally employed with the lest. This study addressed the i mpact of ruing this system on the score patterns generated by the HRNB in 64 clients with localized injuries to one of four quadrants of the brain. Results showed that the raw scores show move overall impairmen t than do the T scores, but overall the systems are statistically equa l in their ability to separate the localized groups. The patterns of d ifferences among the systems also differ Although these findings sugge st overall equivalence of the systems, they also show that each may ha ve strengths that will show Icp in different analyses. A process of us ing both scoring systems for their own unique information is advocated as most appropriate at the current time until additional research add resses the questions raised in this study and elsewhere.
