Factor scores with repeated measures PreviousNext

I have three waves of responses from multiple customers. I want to compute the factor scores from these responses to be used for subsequent analyses.

What is the best approach in this case? I understand that I should account for the dependence across the repeated measures from the same individual, but am not sure how to carry out in MPlus. Kindly advice.

Look forward to your assistance.

Since you mention factor scores, I assume that you have responses to a multi-item measurement instrument at each time point. So just set up a longitudinal factor analysis model where the number of variables is the number of items times 3 (the number of time points). If long'l FA is unfamiliar to you, see our Topic 1 teaching on the website.

Thanks Dr. Muthen for your response. I looked up the Topic 1 teaching note (page 165)on the website, but only found the figure, which seems to accurately capture what I am looking for.

I have multi-items (a1-a10) at each of the tree time points for several individuals (id identifies the individuals).

Could you provide some guidance on the code...thanks!!

See multiple indicator growth in either the Topic 3 or 4 course handouts. The beginning of this shows the inputs for testing for measurement invariance across time.
