Can you please tell me the syntax or process to obtain factor scores for an EFA conducted with categorical (or rather, binary) indicators? FSCORES and FSCOEFFICIENT state that they will not run with an EFA.

If you have only one factor solution, for example, EFA 2 2 or EFA 4 4, you should be able to use the FSCORES option. An alternative is to use ESEM which is the same as EFA. See Example 5.24. It is an EFA if you remove the covariates and direct effect.

Thank you for your reply. I am looking at a 2-factor solution. What should I do for that?

TYPE = EFA 2 2;

Thank you again. I am still receiving an error message I do not understand:
*** WARNING in SAVEDATA command
Factor scores cannot be computed for TYPE=EFA. Note that factor scores are
available with the use of EFA factors (ESEM). Request to save FSCORES is ignored.
*** ERROR in ANALYSIS command
OUTPUT options FSCOEFFICIENT and FSDETERMINACY and SAVEDATA SAVE option
FSCORES are not available when there are no latent variables.

Here is my syntax:
ANALYSIS:

! TYPE = COMPLEX efa 1 3 ;
TYPE = complex efa 2 2 ;
estimator = WLSMV;
ROTATION = geomin;
plot: type = plot2;

OUTPUT:

savedata: file is xyz.dat;
save = fscores;
