My impression is that it was created as one thing (by Linehan), and insurance companies latched onto it for its short-term, goal-oriented approach. New therapists could be drawn to where the reimbursements are, plus the fact that there's less skill involved in leading DBT than traditional psychotherapy. I know at least one person (newly licensed) who could not, for the life of her, do anything close to psychotherapy, but she's all aboard the DBT gravy train. I don't think they should charge as much as a counselor, but that's how the system is set up.

That said, those that practice DBT the way it was intended probably have a lot more success than these others that are making people feel so invalidated.
