Abstract We examined the extent to which the Psychological Entitlement Scale (PES), the Interpersonal Exploitativeness Scale (IES), and the Narcissistic Grandiosity Scale (NGS), when taken together, assess a broader construct or three distinct facets. In Study 1, a principal components analysis was conducted, demonstrating that the PES, IES, and NGS should be considered three separate traits rather than one overall construct. In Study 2, confirmatory factor analysis (CFA) revealed that the most efficient and best fitting model contained 8 items of the PES (dropping a reverse-scored item), the 6-item IES, and a revised 6-item model of the NGS. Study 3 replicated the CFA and examined the correlates of the PES, IES, and NGS with measures of narcissism and related measures such as empathic concern and self-esteem. Implications for future assessment of narcissism traits are discussed.
