Description
As part of a comprehensive preschool screening program, the Wechsler Preschool and Primary Scale of Intelligence, Peabody Picture Vocabulary Test‐R, and the Expressive One Word Picture Vocabulary Test were administered to 51 young children, who varied in age form 45 to 76 months (M = 57.5, SD = 4.9). The sample consisted of 21 females and 30 males, of whom 80% were White, 18% Black, and 2% Native Americans. Stepwise regression was used with the WPPSI Verbal, Performance, and Full Scale IQs as criterion variables (dependent variables) and the PPVT‐R and EOWPVT as the predictor (independent variables). The stepwise regression technique was helpful in identifying the specific combination of independent variables that could best be used to predict WPPSI scores. Results indicated that the PPVT‐R and QT can be used successfully as predictors of the WPPSI IQs for young preschool children. Implications and limitations for the use of regression equations by clinicians are discussed.
