The current study assessed the viability of mixture confirmatory factor analysis (CFA) for measurement invariance testing by evaluating the ability of mixture CFA models to identify differences in factor loadings across populations with identical mean structures. Using simulated data from a model with known parameters, convergence rates, parameter recovery, and the power of the likelihood-ratio...

There is continued debate about the appropriateness of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) for scale evaluation and latent variable modeling more generally. This study seeks to combine the strengths of EFA, namely flexible evaluation of item-factor structures, while using one of the unique strengths of CFA, the simultaneous adjustment for common method bias ...

This article is the second of two on the use of confirmatory factor analysis (CFA) as a method to assess construct validity. The construct validation criteria required by the conventional MTMM approach are satisfied only by certain ideal data sets, such as those in which the method variance of measures is very low. The CFA approach to multitraitmultimethod (MTMM) data is more general, in that v...

Several studies have employed confirmatory factor analysis (CFA) to evaluate the latent structure of posttraumatic stress disorder (PTSD) assessment measures among various trauma-exposed populations. Findings have generally failed to support the current three-factor DSM-IV PTSD conceptualization, demonstrating the need to consider alternative models. The present study used CFA to evaluate seven...

This chapter first reviews the major consequences of ordinal measurement in Confirmatory Factor Analysis (CFA) models and introduces the reader to the Polychoric correlation coefficient, a measure of association designed to avoid these consequences. Next, it presents the results of a Monte Carlo experiment in which the performance of the estimates of a CFA model based on Pearson and Polychoric ...
