Demonstrated that the extra-factor phenomenon (the two-dimensional solution produced when linear factor analysis is applied to a set of unfoldable items) arises because the metric unidimensional unfolding model is equivalent to the unidimensional quadratic factor model and the unidimensional quadratic factor model is not distinguishable from the…

Administered the Generalized Expectancy for Success-Revised (GESS-R) scale (B. Fibel and W. Hale, 1978) to 547 full-time employees in the United States. Exploratory factor analysis found four distinct factors, and scores on these four subscales were minimally related to the demographics of the subjects and had adequate internal consistency.…

Confirmatory factor analysis (CFA) is a statistical procedure frequently used to test the fit of data to measurement models. Published CFA studies typically report factor pattern coefficients. Few reports, however, also present factor structure coefficients, which can be essential for the accurate interpretation of CFA results. The interpretation…

Bayesian factor analysis (BFA) assumes the normal distribution of the current sample conditional on the parameters. Practical data in social and behavioral sciences typically have significant skewness and kurtosis. If the normality assumption is not attainable, the posterior analysis will be inaccurate, although the BFA depends less on the current…

The author reviewed the use and interpretation of factor analysis in articles published in The Journal of Educational Research articles from 1992 to 2002. He found all major forms of factor analysis among the 25 articles that he reviewed. Exploratory factor analysis was the most common application that he found. He noted only 3 applications of…

This study assessed the factor structure of the Questionnaire on Smoking Urges (QSU), a commonly used assessment of cravings for cigarettes, with a sample of smokers presenting for treatment in a smoking cessation trial. On the basis of previous research, three confirmatory factor analytic models were tested. Model 1 hypothesized a 26-item,…

The present paper shows that the usual factor analytic structured data dispersion matrix lambda psi lambda' + delta can readily arise from a set of scores y = lambda eta + epsilon, shere the "common" (eta) and "unique" (epsilon) factors have nonzero covariance: gamma = Cov epsilon,eta) is not equal to 0. Implications of this finding are discussed…

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…

This study represents an effort to better understand the latent structure of anxiety sensitivity (AS), as indexed by the 16-item Anxiety Sensitivity Index (ASI; S. Reiss, R. A. Peterson, M. Gursky, & R. J. McNally, 1986), by using taxometric and factor-analytic approaches in an integrative manner. Taxometric analyses indicated that AS has a…

Objectives: To describe the development of an original scale that measures perceived school climate for active travel in fourth- and fifth-grade girls and boys. Methods: The data were analyzed using confirmatory factor analysis (CFA) to provide evidence of factorial validity, factorial invariance, and construct validity. Results: The CFA supported…

Spearman's "law of diminishing returns" or SLODR refers to a decrease in "g" saturation as ability level increases. SLODR has been demonstrated in a number of intellectual batteries but several important aspects of the phenomenon are not yet well understood. We investigated the presence of SLODR in the Kaufman Assessment…

This construct validation study investigated the factor structure of the Test of English as a Foreign Language[TM] Internet-based test (TOEFL[R] iBT). An item-level confirmatory factor analysis was conducted for a test form completed by participants in a field study. A higher-order factor model was identified, with a higher-order general factor…

Due to the relative inability of individuals with intellectual disabilities (ID) to provide an accurate and reliable self-report, assessment in this population is more difficult than with individuals in the general population. As such, assessment procedures must be adjusted to compensate for the relative lack of information that the individual can…

The objectives of this study are to assess the psychometric properties of an adapted version of the Maslach Burnout Inventory-General Survey (MBI-GS) for academic staff in South African higher education institutions and to investigate differences between the burnout levels of different demographic groups. A survey design was used, with stratified…

Despite controversy in the literature, the present article assumes that the adult learning theory provides a powerful framework for evaluating training practices. This study explores the degree to which adult learning traits are embedded in optional seminars, the primary form of formal in-service teacher training in Cyprus and a traditional,…
