To explore the relationship between spatial ability and both image quality and image process efficiency, 79 subjects completed spatial tests, imagery questionnaires, and laboratory tasks. Laboratory measures of process efficiency and image quality were strongly related to spatial test performance and weakly related to one another. (Author/BW)

Eleven curative factors form a triangular framework for conceptual integration of the concerns, developmental dynamics, theoretical perspectives, and leader behaviors that characterize group counseling. The framework is useful for determining effective leader interventions, planning group activities, and generating research hypotheses. (Author)

The reliability and factor structure of the Ohio Work Values Inventory were satisfactory for 388 administrators. Differences were found in levels of administration and sex. (Author)

The construct validity of a 17-item exploratory academic self-concept subscale derived from the Piers-Harris Chidlren's Self-Concept Scale was investigated. Its empirical factor structure and its correlation with two other academic self-concept instruments were analyzed. Research use only is recommended pending rewriting of this exploratory…

The development and construct validation of the Dimensions of Self-Concept (DOSC), Form H, are described. The 20-item subscales of the preliminary research form furnished parallel estimates of reliability ranging from .83 to .91. The five subscales show promising construct validity, as evidenced by their factor structure. (Author/BW)

The Learning Style Inventory assesses learners' preferences. This study was designed to determine reliability and construct validity of Kolb's original ipsative instrument and an alternate normative form. The alternate version was found as reliable as the original, was equivalent in measuring characteristics, and demonstrated comparable construct…

College students completed a student perceptions of teaching effectiveness questionnaire. Six factors resulted: attitude toward students; work load; course value to students; course organization and structure; grading quality; and level of material. Second-order factors were general quality and difficulty, which was uncorrelated with other ratings…

Investigated the cross-cultural similarity of the factor structure of Wechsler Adult Intelligence subtest scores for 157 adult Mexican workers referred for psychiatric evaluation. Results provide supportive evidence for the general cross-cultural validity for Kaufman's factors of Verbal Comprehension, Perceptual Organization, and Freedom from…

Compared scores of Argentines and North Americans on the Wechsler Adult Intelligence Scale (revised version). Americans were found to perform significantly better in Vocabulary, Arithmetic, Similarities, and Digit Symbol subtests (perhaps related to their higher average school level), but no cultural differences in factor structures were found.…

The purpose of this paper was to examine the factor structure of the Armed Services Vocational Aptitude Battery, Forms 8, 9, and 10. The analyses provided evidence of the replicability of ability constructs across diverse samples. (Author/PN)

The factor structure of the Adult Norwicki-Strickland I-E Scale, sampling 174 college students, indicated differential factor dimensionality for males and females. The findings also support the contention that I-E is multidimensional in nature; however, these dimensions reflecting factorial validity have not been found to be consistently reliable…

Procedures for assessing the invariance of factors across data sets often use the least squares criterion, which appears to be too restrictive. Tucker's coefficient of congruence is proposed as an alternative. A method that maximizes the sum of the coefficients of congruence between two matrices of loadings is presented. (Author/JKS)

A multitrait-multimethod (MTMM) matrix was formed in which nine evaluation dimensions were the multiple traits, and different offerings of the same course were the multiple methods. Findings from the MTMM analysis and confirmatory factor analysis provide strong evidence for the multidimensionality of student ratings. (Author/BW)

The factor make-up of the Protestant Work Ethic, first presented by M. Weber, was explored, and the relationship between endorsement of the Protestant Work Ethic and academic achievement was studied in a sample of 257 high school seniors. The independent variable was level of endorsement of the Protestant Work Ethic. The dependent variable was…

Because ignoring the missing data in an evaluation may lead to results that are questionable, this study investigated the effects of use of four missing data handling techniques on a survey instrument. A questionnaire containing 35 5-point Likert-style questions was completed by 384 respondents. Of these, 166 (43%) questionnaires contained 1 or…
