Hi evildouble,

I attended and completed this program 2 years ago. It was highly recommended due to severe distress resulting from my BPD. The workbook with this course is excellent. There are 4 or 5 different chapters, and the author is Marsha Linehan.

This isn't a typical "group" approach, at least not here on the East coast anyway. It was more of a classroom set-up and the therapist was an instructor. Not a lot of discussion amongst the attendees, but it may very well be different everywhere else.

Good luck with this. I found the DBT information very informative, and still use the tools today!
