Mentalization-Based Treatment for BPD

SUMMARY In this chapter, we will outline how the concept of mentalizing helps us understand some of the common problems associated with borderline personality disorder and how the theoretical understanding is translated into psychotherapeutic intervention. Mentalizing is the process by which we interpret the actions of ourselves and others in terms of underlying intentional states such as personal desires, needs, feelings, beliefs and reasons. This capacity develops within the context of attachment relationships during infancy and childhood. Borderline personality disorder is conceived of as being a disorder of mentalizing. Vulnerability to a loss in mentalizing particularly in interpersonal or stressful circumstances is a core feature of the disorder. If treatment is to be successful it must either have mentalization as its focus or at the very least stimulate development of mentalizing as an epiphenomenon. Treatment focusing on mentalizing itself is described.
