Standardized the French version of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with a standardization sample of 1,120 participants aged 6 to 16 years. A three-factor solution was a better fit than the four-factor solution of the U.S. version. Factors were identified as Verbal Comprehension, Perceptual Organization, and…

A study concluding that the Wechsler Adult Intelligence Scale (Revised) (WAIS-R) has three clear factors in its structure is critiqued. An alternative factor comparison technique, FACTOREP, is used with identical data. It is demonstrated that the WAIS-R has only two strong factors--verbal comprehension and perceptual organization.

Examined relative goodness of fit of four competing models of Counselor Rating Form-Short across client (N=191) and nonclient (N=111) samples. Results of confirmatory factor analyses supported validity of two-step hierarchical-factor model for both client and nonclient samples. Factor structure of two-step hierarchical-factor model was found to be…

Twelve articles (including two rounds of commentary) consider the proposition that the use of multi-item scales requires only that conditions of simple structure and metric invariance be satisfied at the scale level, rather than for each item individually. The place of the approach in confirmatory factor analysis is debated. (SLD)

A three-stratum theory of intelligence was tested using hierarchical confirmatory factor analysis with the LISREL computer program. Results from subsamples of a group of 6,359 participants aged 2 to 90 years supported the 3-stratum theory, but did not support developmental changes in the organization of cognitive abilities. (SLD)

Six hierarchical clustering methods were applied to subtest intercorrelations for each of the nine age groups in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample. Results point to the possibility of three simultaneously plausible solutions as they support each of the traditional factor structures in varying degrees.…

The fundamental problems that ipsative measures impose for factor analysis are shown analytically. Normative and ipsative correlation matrices are used to show that the factor pattern induced by ipsativity will overwhelm any factor structure seen with normative factor analysis, making factor analysis not interpretable.

Administered Wechsler Intelligence Scale for Children-Revised, Halstead-Reitan Neuropsychological Battery, Peabody Picture Vocabulary Test, and Wide Range Achievement Test to 934 learning-disabled students between ages 8 and 16. Principal-components analysis with varimax rotation indicated existence of seven factors: Verbal Reasoning, Academic…

Obtained Wherry hierarchical factor solution on Wechsler Adult Intelligence Scale-Revised subtests intercorrelations for 108 alcoholic adults. Found ability arrangement consistent with Vernon's structure-of-intellect model. Ability hierarchy consisted of strong general intelligence factor defined by all 11 subtests, which accounted for 49% of…

The Clinician-Administered Posttraumatic Stress Disorder Scale (CAPS) (D. Blake et al., 1990) was administered to 524 treatment-seeking male military veterans. Confirmatory factor analysis results indicate that the best fit is a four-factor first-order solution with moderately to highly correlated first factors of reexperiencing, effortful…

The factor structure of the Children's Depression Inventory (CDI) (M. Kovacs, 1992) was evaluated in a community sample of 1777 children and 924 adolescents. There were five first-order factors for the child group, and the same five plus one more for the adolescents. Results support the stability and predictability of the obtained factor…

Five techniques that combine the ideals of rotation of matrices of factor loadings to optimal agreement and rotation to simple structure are compared on the basis of empirical and contrived data. Combining a generalized Procrustes analysis with Varimax on the main of the matched loading matrices performed well on all criteria. (SLD)

Confirmatory factor analyses of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) using the Canadian normative sample (n=1,100 children) were conducted to verify the four-factor model found in the U.S. normative sample. Results paralleled those of the U.S. sample and support use of the WISC-III factor indexes. (SLD)

A validation study of the Child Sex Abuse Attitude Scale (CSAAS) used confirmatory factor analysis to examine factor structure. Results from a sample of 215 school psychologists supported the hypothesized factor structure of the CSAAS, indicating the plausibility of a four-factor first-order and a single-factor higher order structure for the…

An alternative strategy for computing factor scores was introduced and compared to a popular scoring procedure. The new strategy, which involves unit-weighted composites of standardized items with salient factor score coefficients, is shown superior to the common method. Implications of findings are discussed.
