No. Not a formal one...although I considered the day I set my STBXAH down and said, essentially, I know you've been depressed, drinking in secret, hiding and lying about it and it doesn't work for me anymore, was an intervention of sorts.
It put my relationship on the fast road to over.
So, my experience is all we have to work with is the choices we make around our As. Intervening is trying to change them and leads us nowhere.
Good luck!
