Data obtained from previously published reports of factor analyses concerning aptitudes were re-analyzed using Guilford's structure of intellect model as a theoretical basis for the re-analysis. Results provide support for the model and for its oblique nature. (Author/JKS)

Performed confirmatory factor analyses on the standardization data for the Wechsler Intelligence Scale for Children and the Wechsler Intelligence Scale for Children (Revised) to test competing two- and three-factor hypotheses. Results slightly favored the three-factor solution, but must be weighed against the greater convenience of the two-factor…

The jackknife by groups and modifications of the jackknife by groups are used to estimate standard errors of rotated factor loadings for selected populations in common factor model maximum likelihood factor analysis. Simulations are performed in which t-statistics based upon these jackknife estimates of the standard errors are computed.…

A hierarchical factor analysis of 430 pupils' scores was performed on a matrix of correlations between three measures of cognitive style (analytic-synthetic; field independence; leveling-sharpening) and achievement in mathematics, geography, and English. Findings provide some support for the independence of cognitive style from general…

Underlying constructs of the Nowicki-Strickland Locus of Control Scale for Children (NSLOCSC) were identified through factor analysis and cross-validated with two similar samples of high school students. The two resultant dimensions appeared to measure Social Control (six items) and Self Control (two items). (Author/GK)

A consistently found structure of eight group factors based on occupational activity interest items is presented. This study determines whether a similar second-order, structure of interests would result from factor analysis based on responses to sex-balanced items. Results support the group interest structure obtained in previous analyses.…

Soldiers responded to a desirability and instrumentality scale for 16 potential outcomes obtainable from outstanding performance. Scores were factor analysed and composites formed to reflect each dimension. The 11-item set was a better predictor than the 16-item set. (Author)

Investigated the reliability, validity, and factor structure of the standard 21-item and short 13-item forms of the Beck Depression Inventory. The sample consisted of 163 participants in a methadone maintenance program. Results support the use of the short form as a reliable and valid brief screening measure of depression. (Author)

Investigated the relationship between level of self-concept and personality factors in 130 high school students, using as self-concept measures, subtests from the Index of Adjustment and Values, the Self-Esteem Inventory, and the Tennessee Self-Concept Scale, and using the High School Personality Questionnaire as a measure of personality factors.…

A data analysis model called CANDELINC performs a broad range of multidimensional data analyses. The model allows for the incorporation of general linear constraints. Several examples are presented. (JKS)

Outlines a componential theory of intelligence and describes how this theory might complement different factorial theories of intelligence. Discusses the respective uses of components and factors in educational theory and practice. (Author/GC)

Intercorrelations among 71 items of the Cornell Critical Thinking Test revealed five dimensions: relevance; irrelevance; differentiating levels of reliability of observations or of authorities; accuracy of deduction; and determination of the accuracy of an assumption. The test may lack construct validity, as only the deduction factor could be…

Holland's Self-Directed Search was administered to male and female high school students attending state schools in New Zealand. Results imply that the correspondence between some summary codes on the SDS and existing occupational classifications based on Holland's types may be less than perfect, particularly for females.

This paper demonstrates the feasibility of using the penalty function method to estimate parameters that are subject to a set of functional constraints in covariance structure analysis. Both types of inequality and equality constraints are studied. The approaches of maximum likelihood and generalized least squares estimation are considered.…

Nowicki characterized children's locus of control beliefs in terms of three factors: helplessness, luck, and achievement. This study investigated whether these factors are sufficiently consistent or invariant to be used in further analyses. (Author/DB)
