The triarchic model of psychopathy is a recently developed model of psychopathy that identifies three primary domains: Boldness, Meanness, and Disinhibition. These traits overlap substantially with general and pathological five-factor model of personality (Boldness = low Neuroticism + high Extraversion; Meanness = low Agreeableness; Disinhibition = low Conscientiousness). In the current study (total N = 1,266), we compare domains from the triarchic model of psychopathy and five-factor model in relation to self- and informant-report of external criteria (e.g., pathological traits, antisocial behavior), and quantified their absolute similarity using a profile-matching approach. The corresponding traits from these models show large interrelations and very similar convergent and divergent relations, suggesting that unaltered traits from one can be considered excellent representations of the other. Results are discussed in terms of the benefits of using a unifying trait-based model to study psychopathy, as well as personality disorders more broadly.
