You can save factors scores with exploratory factor analysis in SEM. If you have categorical indicators, there is a problem so you should send your input, data, and license number and I can run it for you in our developmental version. It is fine for continuous outcomes.
Yes, ESEM became available in Version 5.1. See the Version 5.1 Language and Examples Addendums on the website with the Mplus Users' Guide.
Yes, TYPE=COMPLEX can be used with ESEM.

Dear Dr. Muthen,
I just saved factor scores in ESEM using SAVE=FSCORES, and I just wanted to check about these scores.
I wanted to get a summary of some items. The CFA of them have terrible fit so I thought EFA scores would be better. I decided to work with factor scores as the ESEM model would otherwise become too large to handle easily. Since I could not expor scores from EFA, I tried the ESEM set up and it worked!
Now I would like to check if these ESEM factor scores are the same to the factor scores that would have obtained from EFA scores with the same number of factors (although I understand Mplus does not have this option for EFA).
I have MPlus version 6.1. My items are categorical, the latent variable is continuous.
ESEM without covariates or indirect effects is EFA for the same number of factors. The factor scores from both approaches would be identical.

Thanks! Yes, I checked that ESEM and EFA with same number of factors gave exactly the same results! PS: is it possible to fit SEM with ESEM as when CFA is specified, e.g. using ESEM factors as predictors of other CFA or growth curve factors?
I am attempting to run an ESEM with categorical variables to save factor scores, then explore the interrelationship of these factor scores with factors from two other measures. Is it possible to run an ESEM with categorical variables? If so, are there any helpful resources for how to run this analysis? Thank you!
Hi Linda/Bengt, I have been using ESEM to output my EFA factor scores with no problem but until lately that I ran into this problem:
While the EFA model results seem reasonable, but when I used ESEM to output factor scores, I got the warning that "THE RESIDUAL COVARIANCE MATRIX (THETA) IS NOT POSITIVE DEFINITE" and therefore no factor scores can be saved.
My questions are: 1. Why did I not get the same warning with my EFA run? The ESEM run did give me same model estimates as the EFA run. 2. What should I do in order to resolve this problem and to get the factor scores? Is this problem related to the missing data issue? Thanks for your advice in advance! Best, Mariah
I am getting a very strange error message when I am attempting to run an ESEM on categorical indicators. The error message reads that one of my variables contains 815 categories when this clearly isn't the case. It is a likert-type item rated on a scale from 0 to 4. I've removed all formatting from the csv file, but am still encountering the same problem. Any assistance would be appreciated. Thank you.
