I need help to figure out the syntax for the following:
Independent Variable is Treatment
I want to find out if the change in depression from pre to posttreatment is moderated by sex and several other dychotomous variables.
I tried using the syntax from some other users that have posted here, but I am getting an error.
my basic regression is
Depression Post on Depression Pre
but I don't know how to constrain the path.
i need to get the unconstrained paths for males and females
and then the constrained paths for males and females
and calculate the chi square diff test.
I would really appreciate any help with this. Ideally, if there is a syntax already written on this, I could then replace the variables to match mine.

You could do a multiple group analysis with gender as the grouping variable. The unconstrained model is:
post ON pre;
The constrained model is:
post ON pre (1);
