"Real" DBT groups tend to be expensive. Modified groups are usually cheaper and you still learn the same skills.

My current group is a DBT process group. You get to process your week and learn skills to practice rl issues.

There's also now something called radically open DBT? So there are now more developers of DBT besides Marsha Linehan. Modalities are always evolving. DBT came from CBT. DBT will also grow into a new style.
