This exploratory study examined the validity of the Luria-Nebraska Neuropsychological Battery-Children's Revision with a group of 100 previously diagnosed learning-disabled children. All children were administered the Luria-Nebraska Neuropsychological Battery-Children's Revision, Wechsler Intelligence Scale for Children-Revised (WISC-R), and Wide Range Achievement Test (WRAT). A Q-technique factor analysis using the subtests of the Luria-Nebraska-Children's Revision as dependent measures yielded three distinct sub-groups. Follow-up MANOVAs between the three subgroups using the WISC-R IQ scores and WRAT subtest scores revealed that only two groups differed on one variable (WRAT Spelling). It was concluded that the subgroups identified by the Luria-Nebraska Neuropsychological Battery-Children's Revision appear to be very similar and that the failure of this neuropsychological test battery to differentiate meaningful subgroups may relate to its poor construct validity.
