This paper presents four methods for determining the number of factors to retain: (1) determining an eigenvalue greater than unity (K1); (2) the scree test; (3) the minimum average parallel approach; and (4) parallel analysis. Three of the four methods are illustrated through an example. Although the eigenvalue greater than unity and the scree…

Summarizes the problem of factorial invariance in between-group difference studies, proposes a simplified notation intended to facilitate discussion of the problem, and suggests a structured approach for testing large models. Two computer programs are offered to help with the computation. (SLD)

Gives sufficient and necessary conditions for the observability of factors in terms of the parameter matrices and a finite number of variables. Outlines five conditions that rigorously define indeterminacy and shows that (un)observable factors are (in)determinate, and extends L. Guttman's (1955) proof of indeterminacy to Heywood (H. Heywood, 1931)…

H. Kaiser (1992) has shown that the sum of coefficients alpha of a set of principal components does not change when the components are transformed by an orthogonal rotation. In this paper, the rotational invariance and the successive alpha-optimality are integrated and generalized in a simultaneous approach. (SLD)

Provides a fully flexible approach for orthomax rotation of the core to simple structure with respect to three modes simultaneously. Computationally the approach relies on repeated orthomax rotation applied to supermatrices containing the frontal, lateral, or horizontal slabs, respectively. Exemplary analyses illustrate the procedure. (Author/SLD)

A sufficient condition in terms of the unique variances of a common factor model is given for the results of factor analysis to come closer to those of principal components analysis. In general, vectors corresponding to loading matrices can be related to each other by a specific measure of closeness, which is illustrated. (SLD)

Identifies a general algorithm for orthogonal rotation and shows that when an algorithm parameter alpha is sufficiently large, the algorithm converges monotonically to a stationary point of the rotation criterion from any starting value. Introduces a modification that does not require a large alpha and discusses the use of this modification as a…

In a study of 144 college students, the factorial structure of the Collett?Lester Fear of Death Scale matched the face content of the subscales quite closely, ameliorating the criticism of the scale by R. A. Neimeyer et al. (2003).

Waldrip and Fisher (2000) proposed seven culturally relevant factors that are salient in the educational setting (gender equity, collaboration, competition, deference, modelling, teacher authority, congruence). In relation to these factors, the present study examined differences and congruencies in factor structure (i.e., differences of kind) and…

The assertion that there are a limited set of generalizable good educational practices (Chickering & Gamson, 1987) with a common model of preferred active student engagement in learning (Kuh, 2001) is appealing to those responsible for simply stated institutional outcomes and to the faculty who teach in fields that espouse the same practices…

In practice, vertical scales have been continually used to measure students' achievement progress across several grade levels and have been considered very challenging psychometric procedures. Recently, such practices have been drawing many criticisms. The major criticisms focus on dimensionality and construct equivalence of the latent trait or…

Purpose: The purpose of this paper is to investigate Universiti Utara Malaysia UUM lecturers' perception of the decision regarding adopting e-learning as a teaching tool. Design/methodology/approach: Data were collected from 244 lecturers in Universiti Utara Malaysia. Internal consistency using Cronbach alpha and exploratory factor analysis with…

The development, maintenance, and integration of multicultural competence into all aspects of psychologists' work is critical to ethical practice in an increasingly diverse society. Measurement of multicultural competency is critical to investigating the development of multicultural competence and the effectiveness of multicultural competency…

The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components…

International undergraduate students attending U.S. colleges completed a common ?hassles? assessment, the Inventory of College Students? Recent Life Experiences (ICSRLE). Previous structure and validation studies with this measure have been limited to North American students. Using exploratory and confirmatory analyses, a distinct structure of 6…
