I'm hoping for an opinion about constraints in multilevel sem. I am developing a model were one latent variable varies across levels 1 and 2. Would it be advisable to constrain the factor loadings to be the same across both levels?
Keep in mind that I mean a complete sem not just cfa. Thank you.

No, it would be inadvisable to constrain the factor loadings or other parameters across levels. Experience indicates that the same model will not fit at both levels.
Hi I am testing a multilevel model. I added factor loading equality constraints to the model, but failed to find any instructions about adding intercept constraints. Any help would be much appreciated.
this is the model with factor loading constraints:
fearhap by q1 q6 q2 q5 q3;
fearhap by q6(1); fearhap by q2(2); fearhap by q5(3); fearhap by q3(4);
fearhap2 by q1; fearhap2 by q6(1); fearhap2 by q2(2); fearhap2 by q5(3); fearhap2 by q3(4);
We conducted two separate lines of MCFA (multilevel confirmatory factor analysis analyses)..... For the two-item scale of LS, a good fit for the scalar invariance (RMSEA = 0.01; χ 2 = 14.42, df = 7) and an acceptable fit for the factor mean invariance (RMSEA = 0.062; χ 2 = 1440.54, df = 19) models was established.
Pasted just for your info. Maybe my reading of the article is not accurate. Anyways, thank you very much for your answer. really helpful.
I read their article and those pages don't make sense to me. Comparing countries with respect to indicator intercepts and factor means can only be done in conventional SEM by a multiple-group analysis, not a multi-level analysis. I will contact the authors to see what they did.
