In a multiple group ESEM analysis under WLSMV estimator, I have a co-variate that I am interested in checking whether it has got DIF effect with the ordinal items of interests that form latent variables.
I was wondering if this is feasible. And if there is indication of DIF, is it sufficient/reasonable to allow a regression path between the covariate and the specific item (given that under WLSMV loading and threshold are not really separate)?
I am not sure if this is possible with ESEM. Try doing this with MODEL TEST.

Would modification indices pick up the non-zero paths between the co-variate and the items?
For example, I regressed the co-variate to the latent factor, then I regressed the co-variate to an item (ordinal measure). The parameter is free for the latent factor, but fixed to 0 for the item. This seems to "trick" the program to produce MI indices for the non-zero path between the covariate to all the items (not just the one contrained item).
Does this more or less capture uniform DIF between the co-variate and the items?
