Significance of change in R-squared PreviousNext

I am running some regression questions in Mplus using SEM (criterion variables are latent). I begin the model with a single predictor variable, then add a second variable to test it's incremental validity in predicting the criteria over the first variable. I can easily calculate the change in R-squared from the two different models, but I can't figure out how to test the significance of this change.

Any suggestions?

I am not familiar with doing this sort of test. It relies on 2 different runs with parameter estimates that are correlated over the 2 runs.
