| Abstract: | Forty-one young normal adults were administered the Shipley Institute of Living Scale (SILS) and the WAIS-R as part of a validation study of previously published procedures for estimating WAIS-R Full-Scale IQ scores from SILS Vocabulary and Abstraction Scores. Correlations between SILS scores and WAIS-R scores were lower than expected from the literature. Prediction of WAIS-R FSIQ from SILS Vocabulary and Abstraction scores was poor (r = .46, p < .01). Partial support for the use of new procedures for estimating WAIS-R IQ from SILS was obtained. Implications for interpreting SILS scores obtained from subjects similar to those studied were discussed. |
