“…This finding was not unexpected, because Object Assembly has the fewest number of items, making it the least reliable of the subtests (Wechsler, 1981). Low correlations have also been associated with the Object Assembly subtest in previous research (Marsh, 1973;Massad et al, 1988;Satz & Mogel, 1962).…”

“…There were, in fact, no significant Form X Side of Lesion interactions when the magnitude of full-length and short-form scores were compared, nor did the frequency of particular discrepancies in scaled-score points or their categorizations vary significantly with hemispheric side of lesion. Thus the trend observed by Massad et al (1988), that the short-form scores were affected by laterality, and specifically that the shortform scores of RHD patients had discrepancies on the Picture Completion, Picture Arrangement, and Object Assembly subtests that were larger than those of LHD patients, was not substantiated with a larger and more homogeneous sample.…”

“…Alternatively, other researchers determined the percentage of patients correctly classified by the Satz-Mogel short form according to Wechsler IQ standards. Luszki, Schultz, Laywell, and Dawes (1970) reported correct FSIQ classifications for 82% of their patients, whereas Massad et al (1988) found an agreement rate of89%.…”

“…For example, the Object Assembly subtest has so few items that eliminating every second item can produce a very different score. Indeed, some of the lowest correlations between the Satz-Mogel short form scores and the full length test scores have been reported for the Object Assembly subtest (Marsh, 1973;Massad et al, 1988;Satz & Mogel, 1962). For neuropsychologists who complete a pattern analysis of the Wechsler subtests, these are particularly important issues.…”

The ability of the Satz and Mogel (1962) short form WAIS-R to provide equivalent information about IQ scores and age-corrected scale scores was examined as a function of side of lesion for 34 left hemisphere damaged (LHD) and 29 right hemisphere damaged (RHD) patients having primary brain tumors. Correlations between the two forms were significant for all WAIS-R scores with the exception of the Object Assembly subtest for RHD patients. The short form significantly overestimated Verbal IQ, Performance IQ, Full Scale IQ, Similarities and Picture Arrangement subtest scores. It significantly underestimated Object Assembly subtest scores. A marked percentage of patients showed one or more category changes for most WAIS-R scores and two or more category changes for some of these scores. The distribution of discrepancies between scores and the number of category changes did not differ significantly for LHD and RHD patients.Short forms of the Wechsler Intelligence Scales have been developed by eliminating entire subtexts (Sirverstein, 1982) or by eliminating items within subtests (Pauker, 1963;Satz & Mogel, 1962;Vincent, 1979). Both types of changes are problematic in several ways. Although the following discussion will focus on problems associated with the Satz-Mogel short form (Satz & Mogel, 1962), the issues raised apply to other short forms as well.Although correlation coefficients relating the Satz-Mogel short form to full length Wechsler test IQ and subtest scaled scores tend to be relatively high (

“…As a result, z scores from either form were used for the verbal fluency measure, depending in which version of the test was administered. The Satz-Mogel short form procedure (Satz & Mogel, 1962) was used on the Comprehension and Vocabulary subtests of the WAIS-R, and all other WAIS-R subtests with the exception of the Block Design, Object Assembly, and Similarities subtests, which were administered in their entirety to increase the reliability of the Full Scale IQ (FSIQ) scores (Massad et al, 1988;Mattis et al, 1992). For the WAIS-R subtests, z scores derived from age-corrected scaled scores were used to control for the range of age in this sample.…”

Neuropsychological asymmetry in Alzheimer's disease: Verbal versus visuoconstructional deficits across stages of dementia

The incidence of clinically apparent asymmetric profiles of neuropsychological deficits in Alzheimer's disease (AD) patients similar to those reported in the PET literature is currently unclear. This study investigated lateral neuropsychological asymmetry using principal component factor analysis in a sample of 153 patients diagnosed with probable AD. Using factor scores, patients were classified into groups exhibiting asymmetric or symmetric profiles of neuropsychological deficits. In the analysis of lateral asymmetry, 27.5% of patients were classified as asymmetric (10% verbally and 17% visuospatially). Consistent with reports of continued asymmetry beyond the mild dementia stage, asymmetry was exhibited in the mild, moderate, and severely demented groups. These findings of neuropsychological asymmetry across stages of dementia are consistent with the picture of significant neuropsychological heterogeneity in AD that has been emerging in the decade.

The current study investigated the efficacy of a Satz‐Mogel type short form of the WAIS‐R in a closed head injury (CHI) population and whether the short form's effectiveness varied by lesion site. Data were taken from the files of 79 CHI patients, 20 with left hemisphere damage, 15 with right hemisphere damage, 29 with bilateral damage, and 15 with only diffuse damage. Information about IQ scores and age‐corrected subtest scores was examined. As expected, correlations between two forms, for both IQ scores and subtest scores were high. However, there was a remarkable percentage of deviation in scaled score points and changes in intellectual classification for some of these scores. No evidence was found to support the notion that usefulness of the short form varied according to the location of lesion.
