st: mediation by subgroup

Dear statalist,
I run the same model in two subgroups and wish to test whether the coefficients significantly differ in the two subgroups (i.e. chow test).
However, each model includes a mediation effect. Specifically, each model includes:
--- three predictor variables
--- a mediation effect (the effect of one predictor is mediated by a Mediator)
--- control variables
On the internet I have found a moderated mediation test using sureg, at this address:
http://www.ats.ucla.edu/stat/stata/faq/modmed.htm
However, I feel this procedure does not inclde a chow test and does not allow to test whether the coefficient (including the mediation effect) are significantly different between the two subgroups.
Have you any suggestion in this regard?
Thanks
