I have 6 observed categorical variables and in CFA they form two factors (3 to a factor - factors are not related) and the model fits well. I want to use these two factors as dependent variables in a SEM model but i am not sure if this is possible. The model is not identified if i test for second order factors and these factors are only just identified if i run the CFA's seperately for each factor. Do i have a problem? It would be nice to have more indicators but sadly that is not possible. I've just started using mplus and SEM so forgive me if this question seems odd.

You can add observed covariates to the model. It will be identified.
