DBT is a type of cognitive behavioral therapy developed in 1993 to treat borderline personality disorder and reduce suicidal behaviors. It combines standard CBT techniques with acceptance-based strategies. DBT aims to help patients regulate emotions, improve interpersonal skills, and tolerate distress through weekly individual therapy, group skills training, therapist contact between sessions, and a consultation team for the therapists. Key aspects of DBT include balancing acceptance of oneself and the need for change, as well as balancing validation of experiences and problem-solving. Studies have found DBT can significantly reduce depression, hopelessness, and self-harm behaviors among adolescents.
