I'd say that you're right on, Zoo, that this is an aspect of DBT for your therapist. In manualized DBT (in other words, following the protocol set up by Linehan & associates), therapists who are practicing DBT need to function within a team, and each member of the team uses DBT skills with each other while consulting about clients. The belief is that you live, eat and breath DBT and the way you do that is by teaching and helping your clients to use the skills and using the skills in your own life, especially within your consulting team. That said, not all therapists using DBT actually function within a team.

The team approach helps therapists recognize when they might be blurring the boundaries or not adhereing to strict DBT protocol, it's support for the therapist while doing difficult work. When a person is involved in difficult and sometimes emotionally charged material, he/she might find themselves functioning with tunnel vision. A DBT team approach allows a therapist to widen their perspective by consulting about their individual cases and/or groups. Personally, I think that when a therapist draws a "new" boundary or adjusts the boundary, he/she needs to own that boundary and not cope out by referring to their supervisior or consulting team as suggesting the change (just my own bias ). It is important for all therapists to define the degree to which he/she gets "supervision" or takes consultation about your case. It should not ethically be a hidden subject.
