Hi
I'm running a multilevel CFA to check the validity of my scale. The scale has three factors and each factor has 6 items.
When I wanted to check the L2 (or between) part of my model, I aggregated each item for each class. Therefore, my model sounds like this:
%within%
MSTw BY SMst1 SMst2 SMst3 SMst4 SMst5 SMst6; !latent variable Mastery (within)
PERAPPw BY SPerApp1 SPerApp2 SPerApp3 SPerApp4 SPerApp5 SPerApp6; !latent variable performance approach goals (within)
PERAVOw BY SPerAvo1 SPerAvo2 SPerAvo3 SPerAvo4 SPerAvo5 SPerAvo6; !latent variable performance avoidance goals (within)
%between%
MSTb BY Mst1m Mst2m Mst3m Mst4m Mst5m Mst6m; !latent variable Mastery (between)
PERAPPb BY PerApp1m PerApp2m PerApp3m PerApp4m PerApp5m PerApp6m; !latent variable performance approach goals (between)
PERAVOb BY PerAvo1m PerAvo2m PerAvo3m PerAvo4m PerAvo5m PerAvo6m; !latent variable performance avoidance goals (between)
I wonder my approach is correct?
Thanks.

Muthens's answer:
"You don't have to aggregate into mean scores. You can instead use the
Mplus latent variable decomposition - see UG examples of 2-level FA."
