Abstract

ABSTRACT Objectives Empathy and aggression are features of the Dark Triad. They are linked to the BDNF Val66Met polymorphism. Here, we investigated the relationships between this polymorphism and the Dark Triad traits. Methods We genotyped the BDNF Val66Met of 698 college students and measured personalities of the Dark Triad, self-report empathy, and aggression with scales of the Short Dark Triad, Interpersonal Reactivity Index, and Buss and Perry’s Aggression Questionnaire, respectively. Results The Met/Met genotype of the BDNF Val66Met was related to higher scores on Machiavellianism and narcissism as compared with the Val carriers. The association between the BDNF Val66Met and Machiavellianism was mediated by aggression and empathic concern, while the association between this polymorphism and narcissism was only mediated by aggression. Conclusions This study highlights the importance of the BDNF Val66Met to the Dark Triad and reveals psychobiological pathways where aggression and empathic concern mediate the link between the BDNF gene and the Dark Triad.

BDNF Val66Met调节黑暗三合会：移情关注和攻击作为中介

【摘要】目的共情和攻击是黑暗人格的特征。它们与BDNF Val66Met多态性有关。在这里，我们研究了这种多态性与黑暗三合一性状之间的关系。方法对698名大学生进行BDNF Val66Met基因分型，分别用短黑暗三联征量表、人际反应指数量表和Buss & Perry攻击量表测量黑暗三联征、自报告共情和攻击人格。结果BDNF Val66Met的Met/Met基因型与马基雅维利主义和自恋得分较高相关。BDNF Val66Met多态性与马基雅维利主义之间的关联是由攻击性和共情关怀介导的，而这种多态性与自恋之间的关联仅由攻击性介导。本研究强调了BDNF Val66Met对黑暗三联症的重要性，并揭示了攻击和共情关怀介导BDNF基因与黑暗三联症之间联系的心理生物学途径。

The journal publishes reports of experimental and survey studies, including reports of qualitative investigations, on pure and applied topics in the field of psychology. Articles on clinical psychology or on the professional concerns of applied psychology should be submitted to our sister journals, Australian Psychologist or Clinical Psychologist. The journal publishes occasional reviews of specific topics, theoretical pieces and commentaries on methodological issues. There are also solicited book reviews and comments Annual special issues devoted to a single topic, and guest edited by a specialist editor, are published.
