Before revision: When the difference between the CFIs of two models of varying levels of measurement invariance (e.g., equal forms versus equal loadings) is greater than 0.01 , then invariance in likely untenable.
After revision: When the difference between the CFIs of two models of varying levels of measurement invariance (e.g., equal forms versus equal loadings) is less than −(that is, it drops by more than 0.01) 0.01 , then invariance in likely untenable.
