Theory and Research: The Nexus of Clinical Inference
Peer reviewed Peer reviewed
Direct linkDirect link
Claeys, Joseph – Journal of Psychoeducational Assessment, 2013
The practice of individual assessment has been moving toward the empirically derived Cattell-Horn-Carroll (CHC) theory of intellectual ability, which offers a hierarchical taxonomy of cognitive abilities. Current assessment tools provide varying adherence to operationalizing CHC theory, making clinical inference difficult. Expert consensus…

Canivez, Gary L.; Kush, Joseph C. – Journal of Psychoeducational Assessment, 2013
Weiss, Keith, Zhu, and Chen (2013a) and Weiss, Keith, Zhu, and Chen (2013b), this issue, report examinations of the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), respectively; comparing Wechsler Hierarchical Model (W-HM) and…

Factor Structure of the WAIS-R for an Incarcerated Population.
Peer reviewed Peer reviewed
Faulstich, Michael; And Others – Journal of Clinical Psychology, 1986
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)

A Horn Analysis of the Factors Measured by the WAIS-R, Kaufman Adolescent and Adult Intelligence Test (KAIT), and Two New Brief Cognitive Measures for Normal Adolescents and Adults.
Peer reviewed Peer reviewed
Kaufman, Alan S.; And Others – Assessment, 1994
Data from 255 normal individuals were factor analyzed. Variables included subtests from the Wechsler Adult Intelligence Scale-Revised (WAIS-R), the Kaufman Adolescent and Adult Intelligence Test (KAIT), and two new brief measures. Results are interpreted in the context of previous Horn analyses of the KAIT and WAIS-R. (SLD)

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)

Confirmatory Factor Analysis of the WAIS-R: Plausibility of Models.
Plake, Barbara S.; And Others – 1983
A confirmatory factor analysis was used to determine the respective viability of factor structure models for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization data. The traditional verbal-performance split was compared to an alternative model proposed by Gutkin, Reynolds and Galvin. The confirmatory analysis indicated that the…

Reliability, Errors, Significance, and Abnormality: WAIS-R Factor Scores.
Atkinson, Leslie – 1990
Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…
