黑暗三人格（即马基雅维利主义、自恋和精神病态）是描述社交厌恶人格特征的流行结构。近年来，短黑暗三联征（SD3；Jones & Paulhus，2014）已成为评估黑暗三联征构造的流行措施。然而，最近的研究对黑暗三人格结构之间所谓的差异提出了质疑。特别是，理论和经验证据表明，马基雅维利主义和精神病态之间的区别可能站不住脚。为了进一步研究这个问题，我们使用项目反应理论分析了大样本（N = 1983）中的 SD3。我们为每个黑暗三合会构造建立项目响应参数估计，并进一步测试黑暗三合会构造是否可以一起建模。结果表明，马基雅维利主义和自恋不能一起建模，但马基雅维利主义和精神病态、自恋和精神病态的组合产生了可接受的模型拟合。这些结果的含义将根据未来如何解释和研究黑暗三合会的结构进行讨论。 (C) 2017 Elsevier Ltd. 保留所有权利。
The Dark Triad (i.e., Machiavellianism, narcissism and psychopathy) is a popular construct for describing socially aversive personality traits. In recent years, the Short Dark Triad (SD3; Jones & Paulhus, 2014) has become a popular measure for assessing the Dark Triad constructs. However, recent research has called the supposed dissimilarity between the Dark Triad constructs into question. In particular, theoretical and empirical evidence suggests that a distinction between Machiavellianism and psychopathy may not be tenable. In order to investigate this issue further, we analyzed the SD3 in a large sample (N = 1983) using Item Response Theory. We establish item response parameter estimates for each Dark Triad construct and further test whether the Dark Triad constructs can be modelled together. Results show that Machiavellianism and narcissism could not be modelled together, but the combinations Machiavellianism and psychopathy, and narcissism and psychopathy, yielded acceptable model fit. The implications of these results are discussed in terms of how the Dark Triad constructs may be interpreted and studied in the future. (C) 2017 Elsevier Ltd. All rights reserved.
