The development of the pathognomonic, left sensorimotor, and right sensorimotor scales for the Luria‐Nebraska neuropsychological battery — children's revision

Abstract

Three additional clinical summary scales have been developed for the Luria‐Nebraska Neuropsychological Battery — Children's Revision (LNNB‐C). This paper reports preliminary findings for the LNNB‐C Pathognomonic, Left Sensorimotor, and Right Sensorimotor scales, whose items were selected in a derivation sample (N = 201: 125 normal, 76 brain impaired). The Pathognomonic scale is comprised of items that maximally discriminate brain impaired from unimpaired children. Items requiring lateralized performance were assigned logically to the Left and Right sensorimotor scales. Analysis of the results indicated, that on cross validation (N = 149:91 normal, 58 brain impaired), significant differences were found in the performance of brain impaired and unimpaired children for each of these scales. The scales also demonstrate acceptable levels of reliability (internal consistency). In a final analysis, classification analyses following a discriminant function analysis suggest that the inclusion of the Pathognomonic and Left Sensorimotor scales improve the statistical discrimination of brain damaged from normal children.
