The Wechsler Adult Intelligence Scale--Fourth Edition (WAIS-IV) is one of the most well-known tests in the field of adult intelligence assessment. This study explores the validity of the Egyptian adaptation for the subscales of the WAIS-IV. Confirmatory factor analysis (CFA) indicated that the first-order, second-order, and bifactor models of both…

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…

Investigated the factor structure of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) for incarcerated individuals (N=234). Coefficients of congruence between the current factors and those of the WAIS-R standardization sample indicated a high degree of correspondence. (Author/BL)

Pattern and level of performance on the WAIS-R (Wechsler Adult Intelligence Scale Revised) and the Luria-Nebraska's Intelligence, Memory, and Motor Scales were examined for 93 neurologically impaired adults. Each set of procedures evidently is indexing the same theoretical constructs. (Author/ABB)

Investigated the cross-cultural similarity of the factor structure of Wechsler Adult Intelligence subtest scores for 157 adult Mexican workers referred for psychiatric evaluation. Results provide supportive evidence for the general cross-cultural validity for Kaufman's factors of Verbal Comprehension, Perceptual Organization, and Freedom from…

Compared scores of Argentines and North Americans on the Wechsler Adult Intelligence Scale (revised version). Americans were found to perform significantly better in Vocabulary, Arithmetic, Similarities, and Digit Symbol subtests (perhaps related to their higher average school level), but no cultural differences in factor structures were found.…

Obtained a hierarchical factor solution on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest intercorrelations for the nine age groups included in the standardization sample. Findings support the validity of the WAIS-R as a measure of general intelligence and the validity of maintaining separate Verbal and Performance IQs. (Author)

Factor analyzed the Wechsler Adult Intelligence Scale-Revised (WAIS-R) across nine age groups in the standardization sample. When three- and four-factor analyses were performed, the familiar three-factor structure (Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility) was clearly visible.

Research on the Wechsler Memory Scale (WMS) is reviewed, including the relationship of Memory Quotient to Full Scale IQ. Despite its limitations, WMS has been a sensitive test of short-term memory, which may be helpful in identifying dominant (left) temporal lobe impairment. (Author/SJL)

Aims of this study were to determine whether the factor structure produced in earlier research by Kear-Colwell (1973, 1977) on the Wechsler Memory Scale could be replicated in a non-patient population (most research uses patient populations) and also to examine the effects of age, sex, and social class on the performance of normal adults on this…

The present study was designed to (1) investigate the changes in the structure and organization of mental abilities during childhood and adolescence of 514 students as sampled by the Wechsler Intelligence Scale for Children (5 to 15 years) and the Wechsler Adult Intelligence Scale (16 to 18 Years) and (2) interpret, and possibly modify, the…
