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)

Major factors underlying the satisfaction of 107 graduate education students were examined using the Graduate Student Satisfaction Questionnaire. Five factors were found: Satisfaction with Intellectual Stimulation of Instruction, with Freedom to Influence School Policies and Procedures, with Professor-Student Interaction, with Intellectual…

The relationships were examined between the Ball Aptitude Battery (BAB) and the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery. Results showed adequate convergent and discriminant validities for all BAB tests except inductive reasoning, which was factorially complex. (Author/GDC)

The factorial validity of the Coopersmith Self Esteem Inventory was studied in 1397 students, grades six to eight. Results showed substantial validity for the original subscales. (Author/GDC)

Determined the factor structure of the McCarthy Scales for 478 referred rural children. Three meaningful factors emerged: Verbal, Perceptual, and Motor factors for males and General-Cognitive, Verbal, and Memory factors for females. Results suggested the McCarthy Scales reflect a general dimension of cognitive ability rather than distinct…

A summary and interpretation of the recent literature on the indeterminancy of factor scores is given in simple terms. A good index of factor score determinancy is the squared multiple correlation of the factor with the observed variables. (Author)
