✦ Synopsis

The present study investigated the relationship between the Revised Peabody Picture Vocabulary Test (PPVT-R) and the WISC-R for a naturally occurring sample of rural children referred for assessment ( N = 5 3 ) . The results indicated that the PPVT-R was highly correlated with WISC-R scale and subtest scores. Examination of a subsample of developmentally handicapped students revealed substantial reduction in correlational relationships as a function of reduced sample size and restricted range of general ability. While the PPVT-R was found to underestimate all three WISC-R scale scores, the discrepancy between the PPVT-R standard scores and the WISC-R Performance Scale score was the only statistically significant underestimation. Results are discussed in terms of prior research findings and implications for interpretation.
