The present study examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV; D. Wechsler, 2008a) standardization sample using exploratory factor analysis, multiple factor extraction criteria, and higher order exploratory factor analysis (J. Schmid & J. M. Leiman, 1957) not included in the WAIS-IV Technical…

According to the most widely accepted Cattell-Horn-Carroll (CHC) model of intelligence measurement, each subtest score of the Wechsler Intelligence Scale for Adults (3rd ed.; WAIS-III) should reflect both 1st- and 2nd-order factors (i.e., 4 or 5 broad abilities and 1 general factor). To disentangle the contribution of each factor, we applied a…

The concurrent validities of 3 short forms of the Wechsler Adult Intelligence Scale (WAIS) were compared for their prediction of full-scale IQ for 145 male and 159 female psychiatric inpatients. Results support previous research showing better predictive accuracy for L. C. Ward's (1990) seven-subtest short form than the others. (SLD)

Full scale IQ (FSIQ) scores, followed by verbal (VIQ) and performance (PIQ) IQ scores, demonstrated the highest comparability between WAIS-R and its seven subtest form when tested with 1,880 subjects from the standardization sample. Correlations between versions were consistently lower for PIQ than FSIQ and VIQ. Age grouping did not affect…

Validity and reliability were calculated from data in the standardization sample of the Wechsler Adult Intelligence Scale--Revised for 565 proposed short forms. Time saved in comparison with use of the long form was estimated. The most efficient combinations were generally those composed of subtests that were quick to administer. (SLD)

Three short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), developed in 1991, were cross-validated on 207 male and 133 female adolescent psychiatric inpatients and outpatients. Results show psychometric properties for the short forms that are comparable to those of the WAIS-R standardization sample. (SLD)

Validity of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) intersubtest scatter as an indicator of cognitive impairment due to brain dysfunction was studied with 316 brain-damaged men. When compared with the WAIS-R standardization sample, intersubtest scatter was not greater for normal persons of similar intelligence quotient. (SLD)

The predictive power of the short-form Wechsler Adult Intelligence Scale of P. Satz and S. Mogel to provide equivalent information about IQ scores and age-corrected scale scores was not differentially affected by the side of the lesion for 63 patients with brain tumors. (SLD)

A 3-factor solution of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) in 260 adults with suspected head injury suggested relatively good construct validity for the factors, based on correlations with neuropsychological tests. Findings are discussed in terms of the multidimensional nature of neuropsychological tests and WAIS-R factors.…

Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test.
