Is it acceptable to impute missing aggregate scores (factor scores) in Mplus? I have missing factor scores for a math composite, but I do not have access to the individual items that were used for creating the factor score.

Thank you in advance.

Factor scores cannot have missing values so I am not sure what you are asking.

Thank you. I apologies, I should have included more information. The math factor scores have some missingness because some children didn't complete the math subtests. The math composite is an outcome variable in a larger SEM.

Yes, you can impute such variables too. But the quality of the imputations depend on how well other variables correlate and you don't want to rely on it if you have too much missing data.
