Dialectical behavior therapy (DBT) is a multi-week, closed, skill-based therapy group consisting of skill sets learned and rotated during the course. Skill sets include mindfulness, distress tolerance, emotional regulation and interpersonal effectiveness. DBT has been proven effective in treating people who have a history of substance use, impulse control issues, eating disorders, anger management, self-harm and anxiety. DBT for adults is a 16 week class. Additionally, a 6 week DBT class is tailored specifically for adolescents.
