The Dirty Dozen scale is a short measure developed to assess the Dark Triad traits, namely Machiavellianism, psychopathy, and narcissism, which has previously shown good psychometric properties. The aim of this study was to validate a Spanish version of the Dirty Dozen through the assessment of its psychometric properties in a sample constituted by 326 young adults aged 18–34 (M = 20.55; SD = 1.89) from Spain. The Spanish version of the Dirty Dozen showed good internal consistency and acceptable test-retest stability. Likewise, the analysis of the factorial structure supported the three-factor solution and showed a best fit for the bifactorial model. The latent factor of the general Dark Triad was associated with low levels of Honesty/Humility, psychopathic traits, impulsivity, and sensation seeking; whereas a differential pattern of associations between the three specific Dark Triad latent factors and the nomological network was found. Furthermore, the Dark Triad traits showed differential relations with reactive and proactive aggression, verifying the external validity of the Spanish version of the Dirty Dozen. Results support the distinctiveness of the Dark Triad traits and justify the Dirty Dozen as an efficient measure for dark personalities in Spanish-speaking contexts.

追求黑暗三合会

Dirty Dozen量表是用来评估黑暗三合会特征（即马基雅维利主义，精神病和自恋）的一种简短量度，以前曾表现出良好的心理测量特性。这项研究的目的是通过对来自西班牙的326名年龄在18-34岁的年轻人（M = 20.55； SD = 1.89）构成的样本进行评估，以验证西班牙语版本的Dirty Dozen的有效性。西班牙语版本的Dirty Dozen显示出良好的内部一致性和可接受的重测稳定性。同样，析因结构的分析支持三因子解，并显示出最适合双因子模型。普遍的黑暗三合会的潜在因素与低水平的诚实/谦卑，精神病性状，冲动和寻求感觉有关。而发现了三个特定的Dark Triad潜在因子与标称网络之间的关联差异模式。此外，“黑暗三合会”特质与反应性和主动性攻击表现出不同的关系，这证明了西班牙语版本“肮脏十二打”的外部有效性。结果证明了黑暗三合会特征的独特性，并证明了“肮脏十二打”是在讲西班牙语的情况下对黑暗性格进行有效测量的理由。
