Hello, I am wondering if I am checking for measurement invariance of depression over 6 time points correctly, and I hope that someone can let me know if I have the right code. I am measuring CESD at 6 time points, and each time point has 7 indicators. I am correlating the residuals but I did not include that code below because it would be a lot. I am first just checking for configural invariance. My main question is this: I have firstname.lastname@example.org. Should I have that for each time point, or just the first? Thank you for your help.
