Abstract
The validity of two- and four-subtest short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) was investigated using a sample of 45 male and 45 female psychiatric patients. Both short forms were highly correlated with Full Scale IQ, although there was a mean IQ overestimate. Forty-two percent of the subjects were placed in different IQ categories by SF2, whereas a 40% misclassification rate occurred with SF4. SF2 and SF4 estimates were within the 95% confidence limits of Full Scale IQ for 62% and 72% of the subjects, respectively. Shortened administration time reduced the accuracy of SF2, but did not influence SF4 IQ estimates. SF4 validity was better for females than for males.This publication has 16 references indexed in Scilit:
