One alternative approach to the traditional self-report assessment of socially undesirable traits is prototypal matching, which consists of computing indices of a given trait from inventories designed for capturing broad personality dimensions. In the present study, the validity of a psychopathy index derived from a clinical portrayal constructed using the items from the Big Five Inventory (BFI) was tested. Participants were 449 students of three Brazilian states, who responded to the BFI, as well as the Dark Triad traits, the Short Dark Triad and the Dirty Dozen inventories. Positive and moderate correlations emerged between the proposed index and the scores in the Dark Triad, with the strongest relationships occurring with the psychopathy factors of each instrument, as expected. These associations were greater when controlling for acquiescent responding. The findings suggest that the index developed could provide an uncovered assessment of psychopathic traits.
