Theorists have long speculated about narcissistic perfectionism—an outwardly directed need for perfection marked by grandiosity, entitlement, and lofty expectations for others. This study provides evidence of reliability and predictive validity for an emerging model of narcissistic perfectionism using two waves of measurement and multiple data sources (self-report and informant-report) in a sample of 155 undergraduate students. As hypothesized, confirmatory factor analysis showed manifest indicators of narcissistic perfectionism cohered together as a constellation of traits while showing reliability and factorial validity across time and source. Hierarchical multiple regression indicated narcissistic perfectionism uniquely and incrementally predicted anger beyond competing measures of other-oriented perfectionism and narcissism. Informant-reports of narcissistic perfectionism uniquely predicted anger beyond self-reports. These results offer promising empirical support for the often discussed, but seldom tested, concept of narcissistic perfectionism.
