Two- and four-subtest short forms of the WAIS--R: Validity in a psychiatric sample.

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.
