Diagnosis, Classification, and Assessment of Narcissistic Personality Disorder Within the Framework of Object Relations Theory.

Narcissistic personality disorder (NPD) remains a controversial diagnosis, with lack of consensus on essential features of the disorder and its boundaries. Within the framework of object relations theory (ORT), core organizing, structural features define NPD and provide a coherent conceptual framework for understanding clinical features of the disorder. In the ORT model, both grandiose and vulnerable presentations of NPD are characterized by a specific form of self-pathology, reflecting the impact of a grandiose self-structure in the setting of borderline personality organization. The grandiose self-structure provides some stability of self-functioning but does not confer the self-regulatory capacities provided by normal identity formation and is reliant on maintaining a sense of the self as exceptional. We compare the ORT model of NPD to diagnostic criteria in the Alternative Model for Personality Disorders (AMPD) of the DSM-5, highlighting significant correspondence between the two models as well as conceptual differences.
