DIAGNOSIS: Borderline Personality Disorder

TREATMENT: MBT (Mentalization-Based Treatment) Group Therapy for Borderline Personality Disorder


  • Basic premise: Mentalizing is the process by which we make sense of each other and ourselves, implicitly and explicitly, in terms of subjective states and mental processes. Patients with BPD show reduced capacities to mentalize, which leads to problems with emotional regulation and difficulties in managing impulsivity, especially in the context of interpersonal interactions. Mentalization based treatment (MBT) is a time-limited treatment which structures interventions that promote the further development of mentalizing.
