Correlations for Wechsler Intelligence Scale for Children-Revised and the Wechsler Preschool and Primary Scale of Intelligence for Iranian Children

This study focused on the relationship between the Wechsler Intelligence Scale for Children—Revised (WISC—R) and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) given to 40 6-yr.-old Iranian children. Pearson correlations between the WISC—R and the WPPSI IQs and between scaled scores on the corresponding subtests were significant. The comparison of mean IQs and scaled scores indicates that the WISC—R yielded a significantly higher Verbal IQ and higher scores on Information, Vocabulary, Comprehension, and Picture Completion than the WPPSI. The mean difference between corresponding Verbal and Full Scale IQs was not significant. These results suggest that scores on the two instruments correlated well for these 6-yr.-old Iranian children and the content on which IQs for the recently restandardized WISC—R and WPPSI are based are related
