Peer reviewedDiStefano, Christine – Structural Equation Modeling, 2002
Investigated the impact of categorization on confirmatory factor analysis parameter estimates, standard errors, and five ad hoc fit indexes through simulation studies. Results replicate some previous studies but also suggest that tests of parameter estimates will be underestimated and the amount of underestimation will increase as saturation…

Peer reviewedGreen, Samuel B.; And Others – Structural Equation Modeling, 1997
A study of the effect of the number of item response categories on chi-square statistics for confirmatory factor analysis indicates that the chi-square statistic for evaluating a single-factor model is most inflated for two-category responses and becomes less inflated as the number of categories increases.
