Dialectical behavior therapy: current indications and unique elements.

Dialectical behavior therapy (DBT) is a comprehensive, evidence-based treatment for borderline personality disorder (BPD). The patient populations for which DBT has the most empirical support include parasuicidal women with borderline personality disorder (BPD), but there have been promising findings for patients with BPD and substance use disorders (SUDs), persons who meet criteria for binge-eating disorder, and depressed elderly patients. Although DBT has many similarities with other cognitive-behavioral approaches, several critical and unique elements must be in place for the treatment to constitute DBT. Some of these elements include (a) serving the five functions of treatment, (b) the biosocial theory and focusing on emotions in treatment, (c) a consistent dialectical philosophy, and (d) mindfulness and acceptance-oriented interventions.
