I am trying to run a growth model of how fast food intake increases across life events in early adulthood, e.g. leaving parental home, having a child.
I have been reading the paper of Curran, Muthen, Harford 1997
Is this still how you would advise to set up this kind of model?
Should the latent variables have covariances?
Thank you.

Q1: Yes.

Q2: I assume you are referring to the 4 latent variables for each time point - if so, the answer is no.

Thank you. I was also interested in whether the additional latent variables for each time point should covary with i and s. In the 2nd diagram in the paper, there are no covariences shown, including between i and s and between these and the additional latent variables.

That's a research question.
