Dialectical Behavior Therapy (DBT) is a type of talk therapy that teaches skills to help people manage emotions, improve relationships, and cope with distress. It combines individual therapy with group skills training and was originally developed to treat individuals with borderline personality disorder, but is now used for other conditions like depression, eating disorders, and substance use disorders. The "dialectic" in DBT refers to the balance between acceptance and change, helping people accept themselves while working to make positive changes.
