Dialectical behavior therapy is a system of therapy originally developed, to treat persons with borderline personality disorder by Marsha M. Linehan, a psychology researcher at the University of Washington, . DBT combines standard cognitive-behavioral techniques for emotion regulation and reality-testing with concepts of mindful awareness, distress tolerance, and acceptance largely derived from Buddhist meditative practice. DBT is the first therapy that has been experimentally demonstrated to be effective for treating BPD. Research indicates that DBT is also effective in treating patients who represent varied symptoms and behaviors associated with spectrum mood disorders, including self-injury. Recent work suggests its effectiveness with sexual abuse survivors.
