Abstract. The aim of this research was to examine the structure of the Dark Triad and Tetrad traits by answering the question whether a person-centered or a variable-centered approach is more suitable for their description, or its combination. Moreover, we examined whether the inclusion of sadism into the dark traits constellation would change the results. On a sample of 404 participants, both short and full-length measures of the Dark Triad were used, while sadism was assessed via Short Sadistic Impulse Scale. The results of the factor mixture analysis showed that the variable-centered approach is better at describing the Dark Triad, but the inclusion of sadism resulted in qualitatively different latent profiles, suggesting that the person-centered approach could serve in describing the Dark Tetrad. Inclusion of sadism led to the isolation of higher Dark Tetrad-sadism profile in both short and full-length measures and this profile showed the higher risk behaviors and interpersonal problems. Other isolated profiles could be interpreted as lower and higher Dark Tetrad profiles, with some specificities. Results showed that inclusion of sadism contributed to the isolation of profile more prone to sadism, but also to isolation of other profiles, suggesting that it could change the relations among dark traits.

暗三元组和暗四元组的因子混合分析

摘要。本研究的目的是通过回答以人为中心还是以变量为中心的方法是否更适合描述或两者结合的问题，来检验黑暗三合会和四合会特征的结构。此外，我们检查了将虐待狂纳入黑暗特征星座是否会改变结果。在一个 404 名参与者的样本中，使用了黑暗三合会的短期和完整测量，而虐待狂是通过短期虐待狂冲动量表评估的。因子混合分析的结果表明，以变量为中心的方法更适合描述黑暗三联体，但包含虐待狂导致了定性不同的潜在特征，这表明以人为中心的方法可以用于描述黑暗四联体。包含虐待狂导致在短期和全长测量中分离出较高的黑暗四分体虐待狂档案，并且该档案显示出较高的风险行为和人际关系问题。其他孤立的配置文件可以解释为较低和较高的暗四联体配置文件，具有一些特异性。结果表明，包含虐待狂有助于孤立更容易发生虐待狂的个人资料，但也会导致其他个人资料的孤立，这表明它可以改变黑暗特征之间的关系。
