Despite the widespread use of the Dirty Dozen (DD) and Short Dark Triad (SD3) as inventories for antagonist personality constructs, appropriately powered studies on their test-retest reliability (r tt) are lacking. We report the 12-day r tt-s of the DD and SD3 scales. Leveraging the test-retest data, we also calculated their convergent and discriminant correlations while controlling for measurement error. Median r tt-s were.87 and.90 (N = 500) for the DD and SD3 scales, respectively, substantially higher than their internal consistencies. Convergent correlations were.77,.63 and.64 for Machiavellianism, Narcissism and Psychopathy, respectively. Discriminant correlations between the Machiavellianism and Psychopathy scales had a median of.65, pointing to their being effectively indistinguishable traits in the SD3 and DD. The DD and SD3 items had median r tt-s of.69 and.71, respectively. We emphasize the importance of the r tt for scale development and validation
