I was in the SATT program at the VA Clinic in Lake City, Florida on and off for ten years. They teach DBT for substance abuse, mental health problems, and chronic pain problems. The teachings help if you can stay focused enough to practice them.

If your basic needs, under Maslow's Hierarchy of Human Needs, are not being met, you will not be able to stay focused to practice the DBT principles even if you are not that mentally ill.
