WISC-III and KAIT results in adolescent delinquent males

The WISC-III and Kaufman Adolescent and Adult Intelligence Test (KAIT) were administered to 30 delinquents in a county youth center as part of their routine psychological assessment. The P > V discrepancy found in earlier studies of delinquent WISC-R IQs was not found with the WISC-III. However, the Fluid IQs on the Kaufmans' test averaged 11 IQ-points higher than the WISC-III IQs. There was a mean difference of 8.66 points between the KAIT Composite IQ and the WISC-III FSIQ, in favor of the former. These findings suggest KAIT IQs that are significantly higher than WISC-III scores (p < .001). The implications are discussed.
