Performance scales for the Luria-Nebraska Neuropsychological Battery-Form I.
Regression equations were developed to adjust raw scores on Luria-Nebraska Neuropsychological Battery-Form I (LNNB-I) clinical scales for the effects of age and education. Corrected raw scores were then used to develop performance scales for the LNNB-I on which normal individuals anchored the low end of the scales and increasingly impaired patients occupied higher intervals. The resulting scales represent equal intervals of age- and education-corrected test impairment for each LNNB-I clinical scale and should facilitate interpretation of LNNB-I test performances.
