Cross-validation of the discriminative effectiveness of the Luria-Nebraska Neuropsychological Battery for learning disabled adolescents.
This study was a cross-validation of the discriminative effectiveness and diagnostic accuracy of the Luria-Nebraska Neuropsychological Battery (LNNB). Subjects were a group of 31 LD adolescents and a matched group of 31 non-learning disabled students whose achievement fell within the low average to average range. Multivariate analysis of variance (MANOVA) confirmed that the LNNB was sensitive to group differences in analyses with either the basic or localization scales. Discriminant function analyses with 12 basic scales yielded overall rates of diagnostic accuracy ranging from 87.1% to 98.4%. A classification rule, based on the number of basic scale elevations, yielded 95% overall accuracy. Rates of overall accuracy for the eight localization scales ranged from 82.26% to 85.48% in discriminant function analyses. A classification rule, basedon the number of localization scale elevations, yielded 81% overall accuracy. The significance and accuracy of various indicators of dysfunction were investigated. Implications for the diagnosis of learning disability are discussed
