The predictive validity and factor structure of the ABC Inventory were analyzed by comparing scores obtained by preschoolers on this test with scores on the Metropolitan Reading Test. The correlational and factor analyses results reveal significant empirical and conceptual relationships between the two tests. (Author/PC)

A quantitative approach was used to identify factors relating to emotional adjustment in 84 dying patients. Emotional adjustment was influenced more by the patient's physical condition, by previous experiences with dying persons, and by interpersonal relationships. (Author)

This study tested the hypothesis that the domain of physical fitness could be defined by the four factors of upper body, trunk, leg, and cardiorespiratory strength and endurance. (JS)

This article reports a study of the influences on the choice of subject matter and teaching methods made by teachers of economics. (Editor)

The effects of initial practice teaching on the self-conceptions of 50 Monash University Diploma in Education students were measured over a pretest-posttest interval of five weeks. (Editor)

This study examined contextual and structural variables of 23 community, private, and agricultural colleges and technological institutes in Alberta and British Columbia. The Aston methodology employed discriminated structural differences in the four groups. (Author/WM)

Regression analysis is one of the more common analytic tools used by researchers. However, multicollinearity between the predictor variables can cause problems in using the results of regression analyses. Problems associated with multicollinearity include entanglement of relative influences of variables due to reduced precision of estimation,…

A constrained component analysis method, which bears a formal resemblance to the confirmatory factor analysis methods developed by K. G. Joreskog (1969) and others, is presented. In confirmatory factor analysis, the constraints allow the testing of formally structural hypotheses within a model that is falsifiable, even in its "just…

Each of the four classic multivariate analysis of variance (MANOVA) tests of statistical significance may lead a researcher to different decisions as to whether a null hypothesis should be rejected: (1) Wilks' lambda; (2) Lawley-Hotelling trace criterion; (3) Roy's greatest characteristic root criterion; and (4) Pillai's trace criterion. These…

An experimental test battery (the Johnson O'Connor Research Foundation battery) designed to measure numerical facility was administered to 1,451 subjects at 12 testing centers across the United States over a 5-month period. Five work samples were included: (1) arithmetic; (2) counting backwards; (3) number reasoning; (4) rule learning; and (5)…

The initial form of the Coping with Death Scale consisted of 30 items designed to obtain responses arranged along a seven-point Likert-type scale. Each item on the scale was derived from personal responses of students who completed a death and dying seminar. The items appeared to fall into two categories: coping with self and coping with others.…

A questionnaire was constructed for the purpose of investigating various aspects of the career choices made by graduate students. The research was to determine the underlying structure of the questionnaire and to compare the capability of nonmetric multidimensional scaling (MDS) and linear factor analysis (FA) to reveal dimensions measured by the…

This report examines the construct validity of the Ball Aptitude Battery (BAB), a multiple ability test battery designed to measure aptitudes related to successful work behavior. Construct validation has focused attention on the role of psychological theory and on the need to formulate hypotheses that can be examined in the validation process.…

The purpose of the present investigation is to examine the influence of sample size (N) and model complexity on a set of 23 goodness-of-fit (GOF) indices, including those typically used in confirmatory factor analysis. The focus was on two potential problems in assessing GOF: (1) some fit indices are substantially influenced by N so that tests of…

This study was undertaken to compare non-metric multidimensional scaling (MDS) and factor analysis (FA) as means of assessing dimensionality in relation to item response theory (IRT). FA assesses correlation matrices, while MDS performs an analysis of proximity measures. Seven data sets were generated; each differed from the others with respect to…
