The Diagnostic and Statistical Manual of Mental Disorders–Fifth Edition ( DSM-5) features two conceptions of Narcissistic Personality Disorder (NPD), one based on the retained DSM-IV’s categorical diagnosis and the other based on a model that blends impairments in personality functioning with a specific trait profile intended to recapture DSM-IV NPD. Nevertheless, the broader literature contains a richer array of potential conceptualizations of narcissism, including distinguishable perspectives from psychiatric nosology, clinical observation and theory, and social/personality psychology. This raises questions about the most advantageous pattern of traits to use to reflect various conceptions of narcissistic pathology via the Personality Inventory for the DSM-5 (PID-5). In this study, we examine the associations of the Personality Disorder Questionnaire–Narcissistic Personality Disorder scale, Narcissistic Personality Inventory–16, and the Pathological Narcissism Inventory and the PID-5 dimensions and facets in a large sample ( N = 1,653) of undergraduate student participants. Results point to strong associations with PID-5 Antagonism scales across narcissism measures, consistent with the DSM-5’s proposed representation of NPD. However, additional notable associations emerged with PID-5 Negative Affectivity and Psychoticism scales when considering more clinically relevant narcissism measures.
