I am testing several competing SEM models, where the baseline model does not have moderators, and the alternative models have one or two paths moderated by a latent construct.
The moderated models employ the xwith syntax, and I noticed that much of the output I typically interpret is not available (e.g., indices to compare model fit).
Where might I read up on an output option or syntax to incorporate to compare the the fit of models requiring 'xwith'?
Thank you for your assistance!

Model fit indices for models with XWITH have not yet been developed in the literature. I would make sure your model fits well without XWITH and then simply see if the slopes for XWITH variables are significant or not. You can also use BIC.
