• Narcissism has traditionally been assessed using explicit measures, yet contemporary measures are limited in their ability to capture people's automatic (i.e., implicit) self-evaluations. Here, we propose the antagonistic narcissism Implicit Association Test (AN-IAT). Three studies (N = 1082) using self-, informant-reports, and other implicit measures tested the psychometric properties of the AN-IAT. The AN-IAT showed high internal consistency and good temporal stability. The measure was positively associated with (antagonistic) narcissism, aggression, and lack of empathy, but unrelated to communal, pathological, and agentic narcissism as well as self-esteem. The AN-IAT predicted self- and informantratings of aggression and empathy beyond self-reports of antagonistic and agentic narcissism, and agreeableness. Together, the antagonistic narcissism IAT is a promising addition to the assessment of narcissism.
