The Relative Contributions of Dark Triad Traits and Multidimensional Perfectionism to the Impostor Phenomenon

Abstract

This study examined the contributions of Dark Triad traits and multidimensional perfectionism to the impostor phenomenon (IP) among college students. While prior research links both to impostor feelings, their combined effects remain unclear. Students completed self-report measures, and hierarchical regression was used for analysis. Dark Triad traits alone did not significantly predict IP. However, adding perfectionism significantly improved the model. Socially prescribed perfectionism emerged as a strong positive predictor, indicating higher impostor feelings with perceived external expectations. Narcissism showed a significant negative relationship, suggesting a protective effect, while Machiavellianism, psychopathy, and other perfectionism dimensions were not significant predictors.
