Hi there,

We are examining the effect of within-patient cognitive change (CC) at Session N on within-patient depression symptoms at Session N+1 across 10 sessions. I would like to test if this repeated-measures effect is moderated by stable interpersonal problems (IP) that were assessed at one time point (i.e., prior to treatment).

I would like to know if there is a way to model the interaction between interpersonal problems and cognitive change across all sessions (i.e., CC_IP = CC1-CC10*IP), rather than at each session (i.e., CC_IP1 = CC1*IP; CC_IP2 = CC2*IP; etc.). For context, we are running our main effect using ML-SEM syntax.

Thank you!
Olivia
