Orthogonal Higher Order Structure and Confirmatory Factor Analysis of the French Wechsler Adult Intelligence Scale (WAIS-III)
Peer reviewed Peer reviewed
Direct linkDirect link
Golay, Philippe; Lecerf, Thierry – Psychological Assessment, 2011
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…

Temporal Relations and Intelligence: Correlating Relational Performance with Performance on the WAIS-III
Peer reviewed Peer reviewed

O'Hora, Denis; Pelaez, Martha; Barnes-Holmes, Dermot; Rae, Gordon; Robinson, Karen; Chaudhary, Tahir – Psychological Record, 2008
Relational frame theory (RFT) explicitly suggests that derived relational responding underlies complex verbally-based cognitive performances. The current study investigated whether the ability to respond in accordance with temporal relations between stimuli was predictive of performance on the four indices of the Wechsler Adult Intelligence Scale,…

Factor Structure of the Wechsler Adult Intelligence Scale-Revised.
Peer reviewed Peer reviewed
Silverstein, A. B. – Journal of Consulting and Clinical Psychology, 1982
Subjected the standardization data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the original Wechsler Adult Intelligence Scale (WAIS) to principal-factor analysis. A two-factor solution was adopted for each scale. The stability of the two factors, Verbal Comprehension and Perceptual Organization, was high both within and between…

Inspection Time and WAIS-R IQ Subtypes: A Confirmatory Factor Analysis Study.
Peer reviewed Peer reviewed
Deary, Ian J. – Intelligence, 1993
Eight-seven adult outpatients in Edinburgh (Scotland) were tested with the Wechsler Adult Intelligence Scale--Revised (WAIS-R) and a test of visual inspection time (IT). Factor analysis confirms that IT correlates more strongly with performance than with verbal intelligence quotient (IQ) scores. Implications for the study of IT and mental tests…

Hierarchical Factor Structure of the Wechsler Adult Intelligence Scale-Revised.
Peer reviewed Peer reviewed
Blaha, John; Wallbrown, Fred H. – Journal of Consulting and Clinical Psychology, 1982
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)

Construct Validity of WAIS-R Factors: Neuropsychological Test Correlates in Adults Referred for Evaluation of Possible Head Injury.
Peer reviewed Peer reviewed
Sherman, Elisabeth M. S.; And Others – Psychological Assessment, 1995
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.…
