The Metacognitive Self-Regulation scale (MSR) was recently improved after subjecting the scale to a comprehensive reanalysis and replacing it with the Metacognitive Self-Regulation Revised scale (MSR-R). However, up to this point, researchers have made no attempts to determine if the MSR or MSR-R performs equivalently for males and females. The first goal of the current study was to examine the MSR-R measurement model for invariance across groups. Second, we examined structural invariance by regressing grade performance on the MSR-R latent factor. The results indicated support for invariance across groups for the MSR-R measurement model, but revealed predictive validity issues when structural invariance was found to be untenable.
