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…

This study described an explicit multidimensional scaling (MDS) model for profile data, the Profile Analysis via Multidimensional Scaling (PAMS) model. It also illustrated the application of this model to the study of the structure of cognitive ability patterns using the Woodcock-Johnson Psychoeducational Battery-Revised (WJPB-R; 1989; 1991) and…

The primary goal of this study was to investigate the underlying structure of the Differential Ability Scales (DAS) using Exploratory Principal Axis Factoring (PAF) with 62 nonclinical preschoolers. While previous factor analyses of the DAS Core subtests revealed the derivation of two distinct factors, the current results revealed only one factor,…

Purposes of this study were to develop an instrument to measure the attitudes of teachers toward the use of instructional television and to administer this instrument to a group of elementary teachers that use the medium on a regular basis. (Author)

Research examined the conception of achievement motivation as a unitary construct. (Author)

Study examined the hypothesis that individual differences are unrelated to types of imaging, and the interrelation of imagery modalities as measured by different assessment devices. (Authors/MB)

Aim of the study is to assess empirically the interrelationships among some of Piaget's and Gesell's behavioral tasks. (Author)

Three methods of assessing college environment (student perceptions, student self-reports, and objective institutional data) were compared by use of multimethod factor analysis, a new technique which removes method variance by focusing on correlations between rather than within methods of measurement.
