Clinicians often attach interpretive significance to high variability among subtest scores in IQ profiles of adults and children. In this study we evaluated the external validity of a relatively new measure of IQ subtest variability, the profile variability index (PVI). Within a sample of referred children, we administered the Kaufman Assessment Battery for Children, the Fourth Edition Stanford...
