I did a DBT group for 2 years.....years ago. Some in our group are still friends cause it did create a connection.
Each group I am sure is handled differently. We did Mindfullness between each section. Our T started off teaching each time then we went around the room to check in & talk through the homework chart about what we did, what we learned & sometimes what we could have done differently & more DBT-ish. Best therapy I ever had & my private T reinforced what was learned. I have actually healed & learned so much from it that I am basically totally functional now (given where I came from with useless therapy for 13 years this was truly a blessing to my life
