Cross-validated the factor structure of the McCarthy Scales of Children's Abilities for 105 kindergarten children. A factor analysis generated five factors, including Verbal Comprehension, Quantitative-Reasoning, Memory, Perceptual-Performance, and Motor factors. The overall factor pattern provides further evidence of the construct validity of the…

Replicated a recent report of the factorial structure of the Multidimensional Health Locus of Control Scale, using rehabilitation patients. Analyses failed to validate the previously reported three-dimensional structure, which indicates a need for careful interpretation of this scale when used with certain populations. An alternative factor…

The vocational interests of disabled adults can be differentiated and are structured in a way that corresponds closely with the interest dimensions of other populations. The United States Employment Service Interest Inventory (USES-II) is recommended for vocational rehabilitation counseling with disabled adults. (Author/ABB)

Reviews WISC-R factor analytic findings for developing a scheme for regrouping WISC-R subtests, consisting of verbal comprehension and spatial subtests. Subtests comprising these groupings are shown to have more common variance than specific variance and cluster together consistently across the samples of WISC-R scores. (Author/JAC)

Examines the structure of human abilities from a hierarchial viewpoint. Findings provided a description of the abilities that children may use in responding to the tasks included in the Wechsler Intelligence Scale for Children-Revised and provided a framework to generate clinical hypotheses about any child's performance. (LLL)

Factor-analyzed the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) scores of emotionally disturbed children (N=181). The results suggested that the structure of intelligence for emotionally disturbed children is similar to that for normal children. WPPSI profile analysis that uses subtest scores may be invalid in clinical settings.…

A factor validity study of the Learning Style Profile (LSP) developed by the National Association of Secondary School Principals was conducted. Developed for use with students in grades 6 through 12, the Profile, which consists of 26 questions representing 24 independent subscales, requires approximately 60 minutes to finish. A random sample of…

The twofold purpose of this study was to investigate the reliability and construct validity of scores on the Japanese version of an academic self-concept scale titled the Dimensions of Self-Concept (DOSC) Form H and ascertain any relationships between scores on the DOSC scale and selected demographic variables, including class, gender, and…

This paper explains the meaning and use of three important factor analytic statistics: factor scores, factor structure coefficients, and communality coefficients. For the discussion, 301 observations of junior high school students 11 measured variables from a previous study are analyzed. While factors provide the researcher with general…

Study was undertaken to determine the degree to which the EPPS, CPI, and 16 PF scales are correlated with the EPI scales and to determine the degree to which the scales in all four inventories are measuring the same common traits. (Authors)

In the present article it is argued that the Least Squares Simplex Data Matrix Solution does not deal adequately with difficulty factors inasmuch as the theoretical foundation is insufficient. (Author/CB)

Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

Paper develops a model which expresses pair comparisons as a function of (a) affective values which form a perfect simplex, (b) systematic (constant over replications) deviations from the simplex-structured affective values, and (c) errors of measurement for the pair comparisons. (Author)

Several alternative solutions are offered to problem posed in AA 513 150. (MB)

Purpose of the investigation was to identify the factorial dimensions of 25 characteristics on a scale for rating research articles. (Authors)
