Abstract

The purpose of this study was to provide data on the validity of using the WPPSI—R with 16 preschoolers who had been referred for psychological assessment. A comparison of the preschoolers' performance on the WPPSI—R and the Stanford-Binet L-M was made. Children ranged in age from 3-0 to 6-0 years, with a mean age of 4–5 yr. The correlations between WPPSI—R and Stanford-Binet L-M scores were strong; WPPSI—R Verbal IQ and Stanford-Binet L-M IQ, r = .85; WPPSI—R Performance IQ and Stanford-Binet L-M IQ, r = .75, and WPPSI—R Full Scale IQ and Stanford-Binet L-M IQ, r = .82. For this very small sample of children whose mean IQ was significantly below average, the WPPSI—R appeared to assess validly their current intellectual functioning. Attention should be given concurrent and predictive validity as well as the efficiency of using the WPPSI—R with other and larger samples of referred children.
