The Relationship between the Kaufman Brief Intelligence Test (K-Bit) and the Wisc-R with Incarcerated Juvenile Delinquents

The K-BIT (Kaufman and Kaufman, 1990) and the WISC-R were administered in counterbalanced order to 40 academically deficient male juvenile delinquents (mean age = 15 years 9 months). The K-BIT IQ Composite and the WISC-R Full Scale scores were positively correlated (r = .64) and the two tests tended to yield similar scores when administered concurrently to the same person (difference = .45 points). This nonsignificant difference is in contrast to the approximately 6-point difference found between the K-BIT and WISC-R with normal (Kaufman and Kaufman, 1990) and referred (Prewett, 1992) students. The results provide support for the K-BIT as a screening instrument when the WISC-R is the follow-up or comprehensive measure of intelligence with juvenile delinquents.
