Research on sex differences in the association of psychopathy with fluid intelligence is limited, and it remains unknown if fluid intelligence plays a meaningful role in explaining the psychopathy-aggression link for men and women. The present study aimed to test for sex differences in the relation between the four-facet model of psychopathy and intelligence, and to assess whether fluid intelligence moderates the link between psychopathy and aggression. In a community sample of men ( = 356) and women ( = 196), we assessed psychopathy using the Psychopathy Checklist: Screening Version (PCL:SV), fluid intelligence using the Raven's Progressive Matrices, and types of aggression using the Aggression Questionnaire (AQ). Hierarchical regressions showed that the psychopathy lifestyle facet was negatively associated with intelligence and there were no sex differences. Our analyses for types of aggression revealed sex differences and similarities. For both men and women, total AQ scores were predicted by higher antisocial facet scores. Lower intelligence moderated the link between higher antisocial facet scores and aggression in men, but not for women. Physical aggression in women was associated with higher interpersonal, affective, and antisocial facet scores, whereas for men, it was only associated with higher antisocial facet scores. Verbal and indirect aggression were associated with higher intelligence in both men and women. For men only, higher antisocial facet scores were associated with verbal and indirect aggression. Higher intelligence moderated the link between the lifestyle facet and indirect aggression for women, whereas for men, it moderated the link between the affective facet and indirect aggression. This study further highlights sex differences in mechanisms of psychopathy-related aggression, which need to be considered in the development of violence interventions and risk assessment.
对精神变态与流体智力之间关联的性别差异的研究有限，目前尚不清楚流体智力是否对解释男性和女性的精神变态-攻击关系具有重要作用。本研究旨在检验精神变态的四因素模型与智力之间的关系是否存在性别差异，并评估流体智力是否调节精神变态与攻击之间的联系。在一项男性（n=356）和女性（n=196）的社区样本中，我们使用《精神变态检查表：筛查版》（PCL:SV）评估精神变态，使用瑞文渐进矩阵评估流体智力，使用《攻击问卷》（AQ）评估各种类型的攻击。层次回归显示，精神变态的生活方式因素与智力呈负相关，且不存在性别差异。我们对各种类型攻击的分析揭示了性别差异和相似性。对于男性和女性，AQ 总分均由较高的反社会因素得分预测。较低的智力调节了较高反社会因素得分与男性攻击之间的联系，但对女性则没有。女性的身体攻击与较高的人际、情感和反社会因素得分有关，而男性的攻击仅与较高的反社会因素得分有关。言语和间接攻击与男性和女性的智力均呈正相关。仅对男性而言，较高的反社会因素得分与言语和间接攻击有关。较高的智力调节了女性生活方式因素与间接攻击之间的联系，而对男性而言，它调节了情感因素与间接攻击之间的联系。本研究进一步强调了与精神变态相关的攻击行为的性别差异，这在制定暴力干预和风险评估措施时需要考虑。
