A Comparison of Four WAIS-R Short Forms in Patients Referred for Psychological Neuropsychological Assessments

In recent years, several short forms of the Wechsler Adult Intelligence Scale-Revised have been developed to provide a more cost-effective means of estimating intellectual abilities. The present study examined the ability of four short forms to estimate intellectual functioning in a sample of medical center (61 male) and state hospital (69 female) patients referred for psychological/neuropsychological assessments. Although all four short forms obtained high correlations with Full Scale IQ, the seven-subtest short form (Ward, 1990) provided greater accuracy with respect to IQ estimation and intelligence classification based on Wechsler's (1981) schema.
