| Abstract: | Examined the relative utility of the Peabody Picture Vocabulary Test, the Quick Test, and the Revised Beta as measures of intelligence in relation to the WAIS and the Revised WISC (WISC-R). 69 juvenile offenders (mean age 15.6 yrs) were selected by a sampling procedure that produced a group representative of the offenders in all of Virginia's state institutions. Although the correlations among the measures were significant, mean differences and percentage-of-classification-agreement tallies indicate that the brief measures are not acceptable Wechsler substitutes with juvenile delinquents. The best overall predictors (the 3 Quick Test forms combined and the Revised Beta) were accurate only about 50% of the time. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
