COMPARISON OF THE WOODCOCK-JOHNSON PSYCHOEDUCATIONAL BATTERY-REVISED AND THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN-REVISED WITH INCARCERATED ADOLESCENTS

The concurrent validity of the Woodcock-Johnson Psycho-Educational Bat tery-Revised Tests of Cognitive Ability (WJ-R COG) was examined by com paring the WJ-R COG to the Wechsler Intelligence Scale for Children-Re vised (WISC-R) for a sample of 52 incarcerated male adolescents. Score s from the WJ-R COG were correlated with scores from the WISC-R IQ and Woodcock-Johnson Psycho-Educational Battery-Revised Tests of Achievem ent (WJ-R ACH). A t-test of related measures for differences between m eans to investigate mean score discrepancies provides evidence of conc urrent validity for the WJ-R COG and the WISC-R. Significant individua l discrepancies in cognitive scores on the two measures were obtained. Correlations between WISC-R IQ scores, WJ-R COG scores, and WJ-R Achi evement Cluster scores indicate that WISC-R Full Scale IQ, WJ-R Broad Cognitive Ability Scores, and Scholastic Ability scores predict achiev ement equally well.
