DBT is a research-based, cognitive behavioral treatment to help clients with suicidal and self-harm behaviors often seen in borderline personality disorder. DBT has been modified as a treatment for other complex and challenging behavioral health disorders that involve emotional dysregulation, such as dual diagnoses, PTSD, eating disorders and severe mood disorders. The term "dialectical" comes from the idea that bringing together two opposites in therapy, acceptance and change, brings better results than either one alone.
