## Abstract

Among test statistics for assessing overall model fit in structural equation modeling (SEM), the Satorra–Bentler rescaled statistic

*T*is most widely used when the normality assumption is violated. However, many researchers have found that_{RML}*T*tends to overreject correct models when the number of variables (p) is large and/or the sample size (N) is small. Modifications of_{RML }*T*have been proposed, but few studies have examined their performance against each other, especially when p is large. This article systematically evaluates 10 corrected versions of_{RML }*T*. Results show that the Bartlett correction and a recently proposed rank correction perform better than others in controlling Type I error rates, according to their deviations from the nominal rate. Nevertheless, the performance of both corrections depends heavily on p in addition to N. As p becomes relatively large, none of the corrected versions can properly control Type I errors even when N is rather large._{RML}Original language | English (US) |
