Mentalization-based therapy, or MBT, is an evidence-based psychodynamic approach that is rooted in in the field of developmental research with conceptual origins in both psychoanalysis and attachment theory. It is also integrative in nature, as it incorporates elements of cognitive, psychodynamic, systemic and social-ecological under the theoretical umbrella of attachment theory. Although MBT is known for its usefulness with patients diagnosed with borderline personality disorders (particularly clients with a history of relational trauma such as maltreatment or neglect), this model of psychotherapy has also proven to be useful with children, adolescents and families in the context of both clinical and outreach settings. In this video Dr. Norka Malberg demonstrates the efficacy of the MBT approach with a young female client who is struggling with abandonment issues while trying to establish a healthy relationship with her mother.
