The most appropriate treatment for Borderline Personality Disorder (BPD) with dialectical behavioral therapy (DBT) is B. Borderline personality disorder. DBT is specifically designed to treat BPD and was created by Marsha M. Linehan in the late 1980s. It is an evidence-based psychotherapy that combines principles of cognitive behavioral therapy with concepts of mindfulness and acceptance, as found in some forms of Buddhist meditation practice. It has been proven to be particularly effective in treating BPD, which is characterized by emotional dysregulation, interpersonal difficulties, unstable self-image, and impulsive behavior. DBT emphasizes a balance between acceptance and change, where patients work towards accepting themselves and their emotional reactions while simultaneously learning skills to decrease maladaptive behaviors and change their thought patterns. The core components of DBT include individual therapy, group skills training, telephone coaching, and a therapist consultation team.
