The Schmid-Leiman (J. Schmid and J. M. Leiman, 1957) decomposition of a hierarchical factor model converts the model to a constrained case of a bifactor model with orthogonal common factors that is equivalent to the hierarchical model. This article discusses the equivalence of the hierarchical and bifactor models. (Author/SLD)

Demonstrates that traditional exploratory factor analytic methods, when applied to correlation matrices, cannot be used to estimate unattenuated factor loadings. Presents a mathematical basis for the accurate estimation of such values when the disattenuated correlation matrix or the covariance matrix is used as input. Explains how the equations…

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,…

This article describes the development of the Comprehensive Assessment of Team Member Effectiveness. The authors used the teamwork literature to create potential items, which they tested using two surveys of college students (Ns = 2,777 and 1,157). The authors used exploratory factor analysis and confirmatory factor analysis to help them select…

A focus on antisocial beliefs and attitudes has informed both the assessment and treatment literature, and practice, in youth justice service provision. This study attempts to broaden the construct of antisocial beliefs and attitudes and reports on the psychometric development of the Antisocial Beliefs and Attitudes Scale (ABAS). The ABAS is a new…

The Body Vigilance Scale (BVS) is a measure developed to assess one's conscious attendance to internal cues. The present report investigated the structure, correlates, and predictive utility of the BVS in nonclinical (N=442) and anxiety (N=135) disorder samples. The findings of Study 1 suggest that the BVS is 1-dimensional in a nonclinical sample,…

Although counseling expectations have been studied in late adolescent and adult samples, little is known about younger adolescents' openness to counseling and perceptions of the counseling process. In this study, 329 middle school students completed the Expectations About Counseling Questionnaire-Brief Form (Tinsley, 1982). An exploratory factor…

Bryant and Smith [(2001). Refining the architecture of aggression: A measurement model for the Buss-Perry Aggression Questionnaire. "Journal of Research in Personality," 35, 138-167] refined the 29-item Aggression Questionnaire and obtained a 12-item short form of the AQ that has yet to be validated with samples outside of North America…

The factor structure of a Chinese version of the Zarit Burden Interview was assessed with a random sample of Chinese caregivers in Canada. The results indicated that the latent constructs identified in earlier studies on caregivers did not fit well when tested with Chinese caregivers. Exploratory factor analysis reported a five-factor solution,…

The 160-item short form of the Personality Assessment Inventory (PAI) was developed for situations in which respondents complete only the 1st half of the test. The present study evaluates the adequacy and comparability of the full and short forms of the PAI in terms of a wide range of psychometric characteristics. In all, 421 participants…
