Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet…

Bifactor latent structures were introduced over 70 years ago, but only recently has bifactor modeling been rediscovered as an effective approach to modeling "construct-relevant" multidimensionality in a set of ordered categorical item responses. I begin by describing the Schmid-Leiman bifactor procedure (Schmid & Leiman, 1957) and highlight its…

The factor analysis of ordered-categorical measures has been described in the literature on factor analysis, but the extension of the analysis to the multiple-population case is less well-known. For example, a comprehensive statement of identification conditions for the multiplepopulation case seems absent in the literature. We review this…

The factor differentiation hypothesis suggests that the factor structure of a set of tests tends to differentiate over time, becoming more complex and articulated. This experimental study provides evidence confirming that hypothesis. (Author/JKS)

The latent trait-state model for estimating stable and changing components of depressive symptomatology in adolescents was studied by investigating the factorial structure of the Center for Epidemiological Studies Depression Scale on 4 occasions with 805 high school students. Findings are discussed with regard to depressive mood fluctuations among…

Factor structure of the Reactions to Tests (RTT) scale measuring test anxiety was studied by testing a series of confirmatory factor models including a second-order structure with 636 college students. Results support a shorter 20-item RTT but also raise questions about the cross-validation of covariance models. (SLD)

This study examines the factor structure of response to the masculinity-femininity (MF) scale of the Comrey Personality Scales for males and females. The use of confirmatory factor analysis for testing hierarchical factor structures and factorial invariance is illustrated. The findings argue that MF is a multifaceted, hierarchical construct.…

Findings are reported for a cross-validated study of factorial validity and invariance of the Maslach Burnout Inventory across gender for elementary school teachers (742 males and 801 females) and secondary school teachers (659 males and 721 females). The study illustrates structural modeling methodology and use of multiple model-fitting criteria.…

Extensions of the confirmatory factor analysis approach to multitrait-multimethod data are demonstrated, and self-other agreement on multiple dimensions of self-concept are evaluated in 2 studies investigating the ability of significant others to infer multiple dimensions of self-concept for 151 Australian and 941 Canadian college students.
