Dialectical Behavior Therapy (DBT) is a type of cognitive-behavioral therapy designed to help individuals manage intense emotions and improve interpersonal relationships. It was developed by Marsha Linehan in the 1980s, primarily for people with borderline personality disorder. DBT combines individual therapy with group skills training, focusing on four key areas: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. The therapy emphasizes the balance between acceptance and change, encouraging clients to accept their feelings while also working towards positive changes in their behavior. DBT is effective for various mental health issues, including anxiety, depression, and substance use disorders, making it a versatile treatment option.
