The Ohio Vocational Interest Survey (OVIS) has been used as an interest measurement tool measuring student interests toward jobs dealing with data, people and things. The purpose for the present paper was to determine the consistency of the OVIS for measuring these three dimensions through factor analysis. The research findings demonstrated which…

Factor analysis was used to investigate the multidimensionality of the Test Anxiety Scale for Children (TASC). Originally designed as a unidimensional measure, subsequent research has indicated more than one meaningful dimension. A principal axis solution and varimax rotation was applied using the squared multiple correlations as initial…

This study reports a factor analysis of the data resulting from a 3-year longitudinal investigation into conservation of number and related mathematical type concepts. Conservation of number, which represents a subset within the concept of conservation, was measured by use of a 20-item, criterion-referenced testing device. The subjects, who were…

The Guttman model of scale analysis has found continued use in sociological analysis despite criticisms placed against it. An empirical example is provided of the use of factor analysis with Guttman scaling even taking into account the criticisms of both very restricted item number of dichotomous responses. Data came from a questionnaire using…

In this article, new arguments and empirical evidence are presented justifying the use of Standardized R - analysis (or equivalently Q - technique) in certain types of factor-analytic studies. The standardized R - analysis analyses the intercorrelations among respondents based on their "ipsative" scores, as opposed to the unstandardized…

A factor rotation scheme is presented which has a property that is interesting for examining factor-structure hypotheses. Given several clusters of tests the orthogonal bounds scheme produces factors which contain these clusters in some optimal sense. (Author)

A new basic algorithm is discussed that may be used to do factor analysis by any of these three methods: (1) unweighted least squares, (2) generalized least squares, or (3) maximum likelihood. (CK)

The Mathematics Attitude Scale (Aiken, 1974) purports to reflect attitude toward mathematics on two basic dimensions, enjoyment and value. While this scale is widely used in mathematics research, the only empirical evidence supporting the two-factor structure is the item analysis of college freshmen responses. The present study examines the…

Results from 188 subjects indicate that most of the items on the test conform to a Rasch latent trait model, but tend to cluster into levels consistent with a hierarchical structure of skills. (AA)

A job satisfaction questionnaire was completed by 4,130 exempt and non-exempt employees of a computer company. Results supported test reliability and validity and suggested exempt employees were more satisfied. Satisfaction with the nature of work and satisfaction with pay and working conditions were the most important facets. (GDC)

College students were administered the Multidimensional-Multiattributional Causality Scale (MMCS). Most of the 3-item subscales had adequate reliabilities. A factor analysis of intercorrelations of responses revealed three pure factors and three ambiguous factors. Results provide partial support for reliability and factorial validity of the MMCS.…

The present study compares the performance of phi coefficients and tetrachorics along two dimensions of factor recovery in binary data. These dimensions are (1) accuracy of nontrivial factor identifications; and (2) factor structure recovery given a priori knowledge of the correct number of factors to rotate. (Author/LMO)

Examines to what extent Hansburg's Separation Anxiety Test matrix of correlations between theoretical factors can be replicated in an independent sample and how closely empirically derived factors from a factor analysis of test scales resemble the composition of Hansburg's theoretically based factors. Results provide minimal empirical support for…

The factorial validity of the Iowa Tests of Basic Skills was investigated. Hierarchical factor analysis was performed with a subset of the standardization data to explore the presence of second-order group factors. Results supported the construct validity of Language and Mathematics subscales. Verbal and Visual Information group factors were…

This study examined selected pyschometric properties of the Health Locus of Control Scale (HLOC) (Wallston, Wallston, Kaplan, and Maides, 1976). Specifically, the HLOC factor structure, factor score reliabilities, and correlations with social desirability were investigated. (Author)
