Assessment

Three socially aversive traits—Machiavellianism, narcissism, and psychopathy—have been studied as an overlapping constellation known as the Dark Triad. Here, we develop and validate the Short Dark Triad (SD3), a brief proxy measure. Four studies (total N = 1,063) examined the structure, reliability, and validity of the subscales in both community and student samples. In Studies 1 and 2, structural analyses yielded three factors with the final 27 items loading appropriately on their respective factors. Study 3 confirmed that the resulting SD3 subscales map well onto the longer standard measures. Study 4 validated the SD3 subscales against informant ratings. Together, these studies indicate that the SD3 provides efficient, reliable, and valid measures of the Dark Triad of personalities.
