Confirmatory factor analytic (CFA) models are frequently used in many areas of organizational research. Due to their popularity, CFA models and issues about their fit have received a vast amount of attention during the past several decades. The purpose of this study was to examine several measures of fit and the appropriateness of previously developed ''rules of thumb'' for their interpretation. First, an empirical example is used to illustrate the effects of nonnormality on maximum likelihood (ML) estimation and to demonstrate the importance of diagonally weighted least squares (DWLS) estimation for organizational research. Then, the results of a simulation study are presented to show that appropriate cutoff values for DWLS estimation vary considerably across conditions. Finally, regression equations are described to aid researchers in selecting cutoff values for assessing the fit of DWLS solutions, given a desired level of Type I error. The results summarized here have important implications for the interpretation and use of CFA models.

Because of the practical, theoretical, and legal implications of differential item functioning (DIF) for organizational assessments, studies of measurement equivalence are a necessary first step before scores can be compared across individuals from different groups. However, commonly recommended criteria for evaluating results from these analyses have several important limitations. The present study proposes an effect size index for confirmatory factor analytic (CFA) studies of measurement equivalence to address 1 of these limitations. The application of this index is illustrated with personality data from American English, Greek, and Chinese samples. Results showed a range of nonequivalence across these samples, and these differences were linked to the observed effects of DIF on the outcomes of the assessment (i.e., group-level mean differences and adverse impact).

The Domain-specific Risk-taking scale was designed to assess risk taking in specific domains. This approach is unconventional in personality assessment but reflects conventional wisdom in the decision community that cross-situational consistency in risk taking is more myth than reality. We applied bifactor analysis to a large sample (n = 921) of responses to the Domain-specific Risk Taking. Results showed that, in addition to domain-specific facets, there does appear to be evidence for a general risk-taking disposition. And this general appetite for risk appears to be useful for predicting real-world outcomes.
