Examined two assumptions about the dimensionality of Rotters' Internal-External (I-E) scale: First, the bipolarity of the two statements within each item pair; second, the unidimensionality of the overall construct. Both assumptions regarding Rotters' I-E Scale were found untenable. (Author/BJG)

The concurrent validity of the Achievement Anxiety Test (AAT) and its factor structure are investigated to provide empirical evidence about the quality of AAT. State and trait anxiety were measured by State and Trait Anxiety Inventory (STAI), mathematics anxiety was assessed by a 24-item revised version of the 98-item Mathematics Anxiety Rating…

In this work, some of the most important instruments used to measure attitudes toward mental illness were analysed. A revision of different experimental investigations which studied attitudes toward mental illness among general public, mental health professionals and patients and their relatives was made. Some of the strategies applied to change…

The relationship of sample size to number of variables in the use of factor analysis has been treated by many investigators. In attempting to explore what the minimum sample size should be, none of these investigators pointed out the constraints imposed on the dimensionality of the variables by using a sample size smaller than the number of…

Explicit formulas are derived for the asymptotic sampling variances and covariances of the maximum likelihood estimators for factor-analysis parameters in the special case where there is just one common factor. The effect of the number of variables on these variances and covariances is indicated. A formula is given showing to what extent the usual…

Illustrates a multivariate approach to item analysis. Previous formulation is extended by investigating techniques simultaneously taking into account scale variance with the goal of reducing the average correlation between scales. Study examines problems in determining optimum values for combinations of item parameters selected for personality…

The factor structure of 109 Occupational Reinforcer Patterns approximating the distribution of the employed labor force of the United States is investigated. These work-reinforcer systems were found to be best represented by a three-factor solution: A Self Reinforcement factor, and Environmental/Organizational reinforcement factor, and a…

Presents results of confirmatory factor analysis of the Kaufman Assessment Battery for children which is based on the underlying theoretical model of sequential, simultaneous, and achievement factors. Found support for the two-factor, simultaneous and sequential processing model. (MCF)

Examined the factor structure of the Luria-Nebraska Neuropsychological Battery-Children's Revision in a population of learning-disabled children (N=100). Factor analysis and varimax rotation revealed three factors: a language-general intellectual factor, a reading-written expression factor, and a sensory-motor factor. (Author/MCF)

Investigated the factor structure of the Bem Sex Role Inventory when used with adolescents. Empirical comparison of actual with expected results supported the measure's validity. (Author)

Gifted elementary students (N=54) completed the Kaufman Assessment Battery for Children. Factor structures for mental processing and achievement subtests were compared to factor structures for children from the standardization sample, revealing similar structures. The most parsimonious structure, however, accounted for under 40 percent of shared…

Administered the Rational Behavior Inventory (RBI) to 510 undergraduates and performed factor analytic procedures. Comparison with the original factors showed nine of the original 11 factor patterns were approximated reasonably. (JAC)
