The value of WISC-R profile analysis for the differential diagnosis of learning disabled children

Examined the research on WISC-R profile analysis germane to the differential diagnosis of learning disabled children in relation to several methodological problems that concern score use and interpretation. The evidence based on Bannatyne's (1974) recategorization of the subtests indicates a Spatial greater than Conceptual greater than Sequencing pattern of performance for learning disabled children. The application of this evidence of group characteristics to the individual child is problematic. The trend is not consistent. In addition, the interpretation of the individual profile is complicated by the unreliability of a few of the subtests, the unreliability of subtest difference scores, the unreliability of Bannatyne category difference scores, and the invalidity of the difference scores for discriminating between learning disabled and other children. It was recommended that clinicians not use the WISC-R profile to diagnose specific learning disabilities. Instead, the analysis may have greater utility in the prevention and remediation of learning problems, especially at the preschool level.
