I am finishing up a grant project in an impoverished "high ACE" community doing exactly this. We have incorporated several interventions, but one that I like most, is Circle of Security.
You can watch a couple of videos on their website to get an idea. It is strengths-based (the message is that we don't have to be perfect as parents, just "good enough") and gets into what they call "shark music" - that subconscious thing that happens when you are triggered by something in your past, even when you don't realize it. It helps us to recognize what we are feeling in those moments and to stop and reflect before we react. By the end of the sessions, parents have a better understanding of their children's behaviors and what they mean. They feel more confident about "being with" their child (and themselves) when they are having strong emotions, rather than trying to distract or order feelings away. As a bonus, the "bad behavior" that their children might have been exhibiting goes away.
I had a parent tell me that "Every parent should take this class, like childbirth class!" I couldn't agree more, the world would be a kinder and gentler place.
I'd be happy to share more, if it is helpful.
Thanks for doing the good work!
