Thank you very much! As shown above, I am doing DSEM without random slopes because my T is small (around 10). Is there any benefit to using DSEM in this case? Would regular multilevel SEM mediation on Mplus give the same result?
Either one. And single-level wide modeling is also an alternative here.

Ok. Thanks for suggestion for regular modeling instead of DSEM given T<10, N is large. I completed the mediation analysis with multilevel SEM because I had Level 2 mediation (code is below).
Turns out the MSEM multilevel mediation results were almost identical to DSEM multilevel mediation.
1) Given DSEM multilevel mediation results were almost identical to MSEM, what is the drawback to using DSEM mediation results?
2) Since MSEM is suggested alternative to DSEM, I want to do lagged analysis with MSEM (previous occasion predicting subsequent). Given T<10, I will not do random slopes. Can I do lagged WITHIN person analysis with MSEM?
2)Is there a benefit to doing MSEM multilevel mediation analysis with Bayesian estimation instead of the default?
