I am interested in the SEM only in the first level; however, if I need to take into account of the multilevel structure, is multilevel SEM the best way to do it, even if I am not really interested in level 2 results? (I assume that the SEM model on the second level should have the same model specification as the first level except for using group level indicators of the level 1 indicators for level 2 factors, constraining loadings to be the same as corresponding level 1 factors) Thank you!
It is not likely that the between specification would be the same as the within specification. Usually there are fewer factors on between than within. You can explore the between-level factor structure using TYPE=TWOLEVEL EFA.

Thank you for your help. I guess I am trying to get a similar thing as in multilevel regression random intercept models. Could there be an analogue in multilevel SEM where the level 1 intercepts of each indicators are free for each cluster instead of having to specify something on the higher level?
