Conducted a meta-analysis of the Kaufman Assessment Battery for Children (K-ABC) to ascertain the numbers of factors in the mental processing subtest of the K-ABC. Analyses yielded sequential and simultaneous processing factors, suggesting that the original K-ABC theory was not supported. (SLD)

Created an adaptation of the Digit Symbol subtest of the Wechsler Adult Intelligence Scale, the Digit Symbol Rotation test, and evaluated its "g" loading with 54 adults. Results suggest the Digit Symbol Rotation test has more factorial validity than Digit Symbol, but remains equally easy to administer and score. (SLD)

Studied the factor structure and other psychometric properties of S. Harter's (1988) Self-Perception Profile for Adolescents for 174 African American early adolescents. Findings yielded six conceptually relevant factors and also indicated gender differences in several domains. (SLD)

Explores posterior analysis in estimating factor score in a confirmatory factor analysis model with polytomous, censored or truncated data, and studies the accuracy of Bayesian estimates through simulation. Results support these Bayesian estimates for statistical inference. (SLD)

A normative typology was developed and applied using multivariate profile analysis of subtest scores of the Universal Nonverbal Intelligence Test (UNIT) standardization sample. The results yielded a seven-profile cluster solution for the Extended Battery, and a six-profile cluster solution for the Standard Battery. Additionally, the results lend…

Developed an Italian version of the Self-Description Questionnaire (SDQ-III) and studied the reliability and factorial validity of this translated instrument. Results show that the translated version has psychometric properties similar to those of the original English version. (SLD)

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. (TJH)

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. (SLD)

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…
