This study tested 60 children, 5 to 8 years old, on a variety of mental, moral, social, creative and cognitive tasks to determine the interrelatedness of those variables and their relationships to the intellectual process of decentration. The subjects were observed while attending a summer program prior to entering grades one through three.…

This paper reports the development of a self-report inventory for measuring work-relevant attitudes. A pool of 72 items was created after a review of the research literature. These items were administered to 89 out-of-school Neighborhood Youth Corps enrollees in Cincinnati and to 78 New Careers enrollees in Durham. Performance ratings were…

A variety of path models involving unmeasured variables are formulated in terms of Joreskog's general model for the analysis of covariance structures. (Author)

This memorandum is the manual for the VARAN (VARiance ANalysis) program, which is the latest addition to a series of computer programs for multivariate analysis of variance. As with earlier programs, analysis of variance, univariate and multivariate, is the main target of the program. Correlation analysis of all types is available with printout in…

A random sample of 225 grade one children were given the Canadian Cognitive Abilities Test (CCAT) on two occasions within seven months. During the second administration the WISC was also administered. KR-20 reliabilities of the CCAT for the two administrations were respectively .83 and .74. The test-retest reliability was .75. The correlation…

The purposes of the present investigation was to factor analyze the results of the administration of the Purdue Elementary Problem Solving Inventory to 361 second-graders. The Inventory was designed to assess twelve distinct skills involved in human problem solving. Tetrachoric intercorrelations were generated from the item scores and a principal…

Factor loadings, used directly or as the basis of binary values, are not appropriate as weights to produce component scores from a rotated solution. A series of examples showing the results of an incorrect measurement of components is given. Several correlation matrices were taken from books on factor analysis and multivariate analysis. Each…

A very general model for the computation of independent cluster solutions in factor analysis is presented. The model is discussed as being either orthogonal or oblique. Furthermore, it is demonstrated that for every orthogonal independent cluster solution there is an oblique analog. Using three illustrative examples, certain generalities are made…

This thesis provides evidence for the existence of a creativity dimension containing figural and verbal subfactors which is independent of intelligence and marginally related to school achievement. The original data of Wallach and Kogan, as well as the data from the Ward, Cropley and Maslany and Wallach and Wing studies were reanalyzed using…

A factor analysis was performed on an intercorrelation matrix of reported drug usage frequencies for seven drug categories at two consecutive periods of time. Subjects were 1,010 Army Vietnam veterans in pay grade E6 or below, aged 26 years or less. Retrospective reporting identified drug usage prior to a tour of Vietnam and during the tour. Four…

Three techniques for assessing the adequacy of correlation matrices for factor analysis were applied to four examples from the literature. The methods compared were: (1) inspection of the off diagonal elements of the anti-image covariance matrix S(to the 2nd) R(to the -1) and S(to the 2nd); (2) the Measure of Sampling Adequacy (M.S.A.), and (3)…

A study was conducted to validate a school behavior rating scale on a sample of 1,153 elementary school children. Results indicate stable means and variances over grades kindergarten through fifth grade and a stable factor structure. Sex differences on behavior ratings favored females over males at all grade levels. School behavior ratings…

The purpose of this study was to construct-validate the REPI. The judgmental data of 25 content specialists were examined. The response data of 416 students were item analyzed and submitted to principal components analyses with orthogonal and oblique rotations. The items were generally representative of the content universe and 50 items optimally…

Part of a Head Start longitudinal study on disadvantaged children and their first school experience, this report provides: 1) a description of interrelationships among certain demographic indices, maternal attitudes, and behaviors reported in the parent interview using factor analytic techniques, and 2) plans for obtaining a reduced set of scores…

Measurement of pupil attitudes can be influenced by the pupil's ability and motivation to read, particularly for those students whose ability is below average. To obtain a valid measure of sixth grade pupil attitudes as they related to Family Life education, the reading factor needed to be eliminated as much as possible. A test utilizing…
