Dear Dr. Muthen,

I attended Topic 7 Multilevel Modeling with latent variables using M-Plus workshop at Johns Hopkins, I have a little question on slide pp141 of your presentation.
The categorical variables are u1-u6, they were treated as categorical factor indicators on the WITHIN level. However, on the between level, they were continuous latent variable. May I know why is that so? Appreciate if you could advise. Also where could I find the example data sets used in the presentation?

On the Between level u1-u6 are random intercepts and therefore continuous latent variables varying across Between-level units.

The example is on the Mplus CD for UG ex 9.9 and also on the Mplus web site under Documentation.

Hi, Dr. Muthen,

I have some questions regarding multilevel mediation analysis with latent variables.

The mediator(M) is in first level and is an latent variable. I want to investigate the x(second level) effect on y(first level) through M(first level). How should I specify the model? I have tried many times, the software told me that the within level factor cannot be used on between level, in this situation, do I need to define an between level factor? Please help, thanks

Yes, define a between factor. You might want to hold loadings equal across levels.

thanks, Do I need to hold the effect of M on Y in between level as the same as the M on Y in within level?

No, they are likely to be different.
