The effect of perceptual speed on performance and paper-and-pencil measures of spatial ability is examined. Perceptual speed is defined as speed in comparing figures or symbols, scanning to find figures or symbols, or carrying out other very simple tasks involving visual perception. It was hypothesized that perceptual speed would have more…

Six methods of measuring factorial similarity were compared with regard to outcome based on two large data sets, one for an intelligence test and the other for a personality test. All indexes yielded comparable results. Comparing factors determined at random, all indexes yielded comparable results leading to a conclusion of dissimilarity.…

The standardization sample of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) was the basis for an analysis of the WAIS-R subscales in relation to demographic variables. Canonical correlation with orthogonal rotation of composite structural components was performed in order to determine interrelations between both sets of variables.…

Research reported in this paper considered the construct validity of a trial essay administered in 1985-87 Medical College Admission Test (MCAT). The addition of the essay caused the non-science factor observed in previous MCAT research to be more strongly defined. (Author/LMO)

The internal-external locus of control scales of Rotter and Levenson and the Marlowe-Crowne Social Desirability Scale were completed by 156 undergraduates. The three-factor structure underlying Levenson's questionnaire was clearly confirmed. Some new evidence for the multidimensionality of Rotter's scale was also presented. (Author/GDC)

A study was conducted to: (1) test for the factorial validity of the 22-item Maslach Burnout Inventory (MBI) separately for 742 male and 801 female elementary school teachers and 659 male and 721 female secondary school teachers in Central Canada; (2) cross-validate findings across a second independent sample for each teacher group; and (3) test…

The purposes of this study are to examine the factorial invariance of responses by preadolescent males and females to a multidimensional self-concept instrument, and to demonstrate the use of confirmatory factor analysis (CFA). Sets of responses by 500 males and by 500 females were each randomly divided in half to form four groups (M1, M2, F1, and…

Two college counseling samples, 150 males and 150 females, were administered two new interest inventories based on a similar factor structure. Considerable convergent and divergent validity for both was apparent in the correlations between the eight Vocational Interest Inventory scales and the 153 Strong-Campbell Interest Inventory General Theme,…

The reliability and validity of the Self-Esteem Inventory developed by S. C. Coopersmith (1975) were evaluated via item-total correlation, discriminant analysis, factor analysis, and analysis of variance of data for 352 Australian adults. The instrument had high internal consistency and discriminated well between subjects with high and low…

A study was conducted to identify types of mental operations of 4- and 5-year-olds and to relate them to the child's age and the educational level of the mother. The sample consisted of 423 white English-speaking children of American parentage, evenly divided by sex and as evenly distributed as possible over the 12-month-age range of 4 to 5 years.…

Evaluation of the Attitudes Toward Statistics Scale (ATS) of S. L. Wise (1985) was extended by examining scale responses in relation to: (1) the scale's factor structure; and (2) the correlation of ATS subscale scores with students' grades in statistics courses at several levels of graduate study, students' sex, and scores on measures of basic…

The reliability, validity, and dimensionality of the revised UCLA Loneliness Scale (ULS) were studied with a group of 199 California college students. Other personality tests were administered to measure social anxiety, alienation, health locus of control, drinking-related locus of control, life satisfaction, and personal values. Sociodemographic…

The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing…

The internal/external (I/E) frame of reference model describes relations among Verbal self-concept (VSC), Math self-concept (MSC), and corresponding achievement scores (VACH, MACH). In support of the model Marsh (1986) found that: (1) VSC and MSC were nearly uncorrelated; (2) the effect of VACH on VSC, and of MACH on MSC, were positive; but (3)…
