DBT is a therapy developed by Marsha Linehan to treat individuals with borderline personality disorder and emotional dysregulation. It combines cognitive behavioral therapy techniques with mindfulness practices. The core of DBT involves teaching clients skills in four areas: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. Through individual therapy, group skills training, coaching sessions, and therapist consultation, DBT aims to help clients learn to manage intense emotions, reduce self-harming behaviors, and build healthier relationships.
