COMPARABILITY OF THE WPPSI-R AND THE S-B-IV AMONG PRESCHOOL-CHILDREN

This study sought to establish concurrent validity between the Stanfor d-Binet: Fourth Edition (S-B:IV) and the Wechsler Preschool and Primar y Scale of Intelligence-Revised (WPPSI-R). Both tests were administere d in a counterbalanced order to 30 preschool- children who were attend ing a summer enrichment program. The results indicated that the Full-S cale IQ of the WPPSI-R and the Composite SAS of the S-B:IV yielded sim ilar scores. Additional findings suggest that although no significant differences existed between the abstract/visual scales of both measure s, a significant difference did exist between the two verbal scales. A nalysis that compared the S-B:IV Factor scores to WPPSI-R IQs found th e same pattern of results. The practical implications of these finding s, and their usefulness for school psychologists who work with prescho ol-aged children, are discussed.
