Hi Statalist, I hope for some ideas - because I am stuck.

I have dyadic (child & caregiver) data with two time points (pre- and post-intervention). The dependent variable is zero-bound continuous (health service use) data.
Co-variates are clinical and demographical variables (both categorical and continuous, both constant and time-varying).
I am aiming to look at treatment effects in groups of caregivers (male vs female) in children (if there is a difference) according to treatment effect.

Which analysis makes the most sense here, when I am interested in the intervention effect in a subgroup of caregivers? I have been thinking about reg with interaction term .reg depvar1 i.treatment##i.cgsex##timepoint i.covariable c. covariable, vce(cluster id)

Does this make sense or am I on the very wrong track here?

Kind regards, Maria
