| Abstract: | The relationship between the WISC-R and WAIS-R was studied in a sample of 30 special education children (22 male and 8 female). Children were administered the WISC-R at an average age of 13.85 years and the WAIS-R at an average age of 17.52 years. ANOVAs indicated that the two tests yielded Verbal, Performance, and Full Scale IQS that were not significantly different. For example, the mean Full Scale IQ was 81.13 for the WISC-R and 82.70 for the WAIS-R. Product-moment correlations also were highly significant, with rs ranging from .76 to .86 for the three scales. The results suggest that, for children of limited intelligence, the WISC-R and WAIS-R provide comparable IQs over a four-year time period. |
