The Triarchic Model of Psychopathy (TPM; Patrick, Krueger, & Fowles, 2009) is a recently developed measure of psychopathy that identifies three primary domains: Boldness, Meanness, and Disinhibition. These traits overlap substantially with general and pathologicalfive-factor models (FFM) of personality (Boldness = low Neuroticism, high Extraversion; Meanness = low Agreeableness; Disinhibition = low Conscientiousness). In the current study, (total N = 702) we compare TPM and FFM domains in relation to self- and informant-report ofexternal criteria (i.e., pathological traits, antisocial behavior), and quantified their absolute similarity using a profile matching approach. The corresponding traits from these models share large interrelations and very similar convergent and divergent relations, suggesting that unaltered traits from one can be considered excellent proxies for the other. Results are discussed interms of the benefits of using a unifying trait-based model to study psychopathy, as well as personality disorders more broadly.
