Four prominent oblique transformation techniques--biquartimin, direct oblimin, promax, and the Harris-Kaiser procedure--are described and compared as to optimality of solution. Additionally, two newly-developed procedures--falling into the category designated as Case III by Harris and Kaiser (1964)--are presented and included in the comparisons.…

Analyses of interscale relations in 235 college students for the Vocational Preference Inventory and Vocational Interest Inventory, based on interest models of Holland and Roe respectively, suggest that the two-dimensional, circular configuration of occupations of personality types may be an oversimplification which impedes the understanding of…

Rotation of canonical components is contrasted with factor rotation and the concept of communalities in canonical analysis is considered. Three possible strategies for rotating canonical components are described: single rotation of all components, separate rotation of each set, and sequential rotation of one set then the other. Constraints,…

Reported are the findings of a research project designed to identify subscales in the "Science Process Inventory" (SPI) developed by Welch in the 1960's to assess student knowledge about the nature and processes of science. Form D of the instrument was used with a random subsample of 435 students who were included in the Harvard Project…

In this paper a rather general theory of oblique factor rotation is outlined. The main results are formulated as four theorems. Necessary and sufficient conditions are derived for two factor matrices to admit identical factor structures and/or factor patterns with factors having unit variances. These conditions are expressed in terms of…

Attention has been drawn to the lack of standards for evaluating the degree of goodness of fit of patterns resulting from a principal components analysis of two data sets. An empirical sampling distribution of the statistic average trace (E'E) as E is obtained in the orthogonal procrustes problem, for various orders of A matrices was developed…

This research tested the proposition that self-concept is unidimensional. Joreskog's Unrestricted Maximum Likelihood Factor Analysis applied to 402 fifth-graders' responses to the Sears Self-Concept Inventory, indicated a twelve factor pattern adequately accounted for variance. Restricted Maximum Likelihood Factor Analysis was than applied to…

This research was undertaken to determine the factor structure of the 26-item revised versions of the Mehrabian (1968) Female and Male scales, a self-report instrument designed to measure achievement motivation. (Author/RK)

The Brand Emotions Scale for Writers (BESW) is a 20-item scale designed to measure writers' emotions immediately before, during, and immediately after writing. This article describes the development of the BESW and the factor structure of the three different scale forms. (BS)

Investigated factor structures of Minnesota Importance Questionnaire and Minnesota Job Description Questionnaire for 189 public school teachers. For both instruments, a three-factor solution was extracted. Although there were similarities in the factors, completely parallel factor structures were not obtained. (Author/NB)

Examined whether common factor structure was evident in Wechsler Intelligence Scale for Children-Revised and Adaptive Behavior Scale-School Edition for 171 children referred for evaluation of learning and behavior problems. Results indicated no common factor structure in instruments, Verbal Comprehension, Perceptual Organization, Independent…

A three subscale inventory designed by Fenigstein, Scheier, and Buss to measure self-consciousness was administered to 297 college students. Fenigstein et al.'s representation was found to fit the data in its original form. Items on the subscales differ nearly as much statistically as they do substantively. (Author/LMO)

K-ABC (Kaufman Assessment Battery for Children) scores for 585 school-age children referred for psychological evaluation were factor analyzed. While it appears that the K-ABC factor structure is quite consistent for both normal and exceptional children, the meaning and names of factors found are open to interpretation. (Author/ABB)

A factor analysis of Fiedler's Least Preferred Co-Worker (LPC) Scale and measure of situational control produced eight factors. Several factors failed to demonstrate internal consistency upon replication. Argues that the LPC and situational control measure are more complex than generally assumed. Suggests further attention to operational…

Australian college students (N=352) completed a questionnaire previously used with American and New Zealand subjects to determine the existence of factors relating to Ego and Super-ego functioning. Results revealed eight factors: Relgious Super-ego, Emotionality, Expediency, Material Self-ideal, Non-religious Super-ego, Ego Control, Compassion,…
