Psychoanalytic Training Institute2007 study by Clarkin, Levy, Lenzenweger & Kernberg comparing DBT, a structured transference-focused (i.e., psychodynamic) therapy and supportive therapy in the treatment of 90 patients diagnosed with Borderline Personality Disorder. The researchers found that, while all three types of treatment were helpful, the transference-focused therapy was effective in the most domains that were measured (suicidality, irritability, anger, impulsivity, verbal assaultiveness and physical aggression) compared with the other two types of therapy.
