The structure and development of borderline personality disorder: A proposed model

Abstract

BACKGROUND: The theory of cognitive analytic therapy is extended to offer an understanding of borderline personality disorder (BPD). METHOD: A structural model (the multiple self states model) and a classification of different levels of developmental damage are proposed. RESULTS: The model offers an explanation of the phenomenology of BPD. CONCLUSIONS: The multiple self states model provides insights that will be useful for clinicians involved in the psychotherapy and management of BPD patients.
