Dark triad personality traits and theory of mind among school-age children

This study examined the associations between four personality dimensions associated with the dark triad (callous–unemotional traits, narcissism, impulsivity, and Machiavellianism) and theory of mind (TOM) abilities among 146 middle school children. Results of hierarchical multiple regression analyses showed narcissism to be positively associated with TOM, callous–unemotional (CU) traits to be negatively associated with TOM, and impulsivity and Machiavellianism to be unrelated to TOM. No significant interactions were found between gender and any of the dimensions of personality. The putative mechanisms linking each personality dimension with understanding of mental states in others are discussed, along with directions for future research.
