Abstract

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.

摘要

尽管 Dirty Dozen (DD) 和 Short Dark Triad (SD3) 被广泛用作对抗性人格结构的清单，但缺乏对其重测可靠性 (r tt ^{)的适当有力的研究。}我们报告DD 和 SD3 量表的12 天r ^{tt -s。}利用重测数据，我们还计算了它们的收敛和判别相关性，同时控制了测量误差。r ^tt -s中位数分别为 .87 和 .90 ( N = 500）对于 DD 和 SD3 量表，分别大大高于它们的内部一致性。马基雅维利主义、自恋和精神病态的收敛相关性分别为 0.77、0.63 和 0.64。马基雅维利主义和精神病态量表之间的判别相关性的中位数为 0.65，表明它们在 SD3 和 DD 中实际上是无法区分的特征。DD 和 SD3 项目的中值r ^tt -s 分别为 0.69 和 0.71。我们强调r ^tt对于规模开发和验证的重要性。
