All theories of BPD rest on the assumption that it develops as a result of
NATURE *and* NURTURE
otherwise known as a biopsychosocial model.
DBT and its founder Dr. Marsha Linehan use a "biosocial model" for their treatement apporach.
TFP and Mentalization use an "Object Relations Model" for treatment.
It is my belief that the two models are complimentary and both should be utilized in the treatment of BPD.
