Use of the WISC-R and PPVT-R with mentally retarded children. 1982

J A Naglieri

Explored the relationship between the Revised Peabody Picture Vocabulary test (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) for a sample of 38 mentally retarded children between the ages of 5--5 to 12--7. The PPVT-R correlated significantly with the WISC-R Verbal (.58), Performance (.48) and Full Scale (.59) IQ scores. There was no significant difference between the mean PPVT-R Standard Score Equivalent (59.9) and the mean WISC-R Verbal (59.5), Performance (62.4), or Full Scale (57.7) IG scores. Implications of these findings for the use of the PPVT-R are discussed.
