This research examines the factor structure and psychometric properties of two well-known Dark Triad personality trait questionnaires: the Short Dark Triad (SD3) and the Dirty Dozen (DD). By analyzing data from 11 (SD3) and 5 (DD) carefully selected studies in the United States and Canada, this meta-analysis uncovers unexpected correlations among questionnaire items, challenging existing assumptions. The study employs a two-stage structural equation modeling approach to evaluate various measurement models. Conventional models, such as the correlated factor and orthogonal bifactor models, fail to explain the irregular correlations. For Dirty Dozen items, a bifactor-(S·I-1) model is more suitable than the orthogonal bifactor model, significantly affecting interpretation. On the other hand, the complex structure of the SD3 necessitates item revision to enhance reliability, discriminant validity, and predictive validity. These findings emphasize the need for refining and clarifying concepts in item revision. Furthermore, the research highlights the overlap between Machiavellianism and psychopathy, particularly in relation to revenge-related items, suggesting the need for differentiation between these traits or the identification of distinct core characteristics.
简版黑暗三性格量表（SD3）和十二黑问卷（DD）。通过分析在美国和加拿大精心挑选的11项（SD3）和5项（DD）研究的数据，这项元分析揭示了问卷项目之间意想不到的相关性，对现有假设提出了挑战。该研究采用两阶段结构方程建模方法来评估各种测量模型。传统模型，如相关因子模型和正交双因子模型，无法解释这些不规则的相关性。对于十二黑问卷的项目，双因子 - （S·I - 1）模型比正交双因子模型更合适，这对解释有显著影响。另一方面，SD3的复杂结构需要对项目进行修订，以提高信度、区分效度和预测效度。这些发现强调了在项目修订中细化和澄清概念的必要性。此外，该研究突出了马基雅维利主义和精神病态之间的重叠，特别是在与报复相关的项目方面，这表明需要区分这些特质或识别不同的核心特征。
