I've never been in a DBT program, but I've had individual Ts who do DBT, and been to DBT skills group and a DBT process group (not at the same time). DBT skills group is more like a class. From my experience, there's not a lot of personal sharing except for examples or homework. And yes, there is homework. I don't really like groups. I'm very shy and don't like opening up to a group of strangers. But the DBT skills group were okay. There was one I really like, and would go back if that T was still running the group. I prefer individual Ts who use DBT. I can more easily apply the skills because they can tailor it directly to my needs.
