DBT has been shown to be effective in treating a wide range of disorders such as depression/suicidal tendencies, post-traumatic stress disorder (PTSD), substance use/addiction, and eating disorders. DBT is often the treatment of choice for people who have high-risk, tough-to- treat conditions or who are seeking treatment for multiple diagnoses. Utilizing group and individual sessions as well as phone counseling, DBT focuses on building mindfulness, distress tolerance, interpersonal effectiveness, and the healthy regulation of strong emotions.
