Investigations into the relationship of the PPVT-R and the WISC-R with incarcerated delinquents.
Examined the relationship between the Peabody Picture Vocabulary Test-Revised ( PPVT -R), the Peabody Picture Vocabulary Test ( PPVT ), and the Wechsler Intelligence Scale for Children-Revised (WISC-R) with 35 incarcerated delinquents between the ages of 13-10 and 16-10. Mean scaled scores were computed across all measures. A statistically significant difference (p less than .01) between the PPVT -R mean scaled score and all other measures was obtained. The PPVT -R correlated significantly (p less than .0001) with the WISC-R VIQ (r = .87), PIQ (r = .78), FSIQ (r = .86) and the PPVT (r = .80), whereas the original PPVT demonstrated significant yet lower correlations with the WISC-R VIQ (r = .78), PIQ (r = .77) and FSIQ (r = .80). The clinical significance of utilizing the PPVT -R as a measure of receptive vocabulary and its practical relationship to the PPVT and WISC-R with a juvenile delinquent population was discussed.
