This systematic review and meta-analysis estimated the size of the relationship between Machiavellianism and intimate partner violence (IPV) perpetration. Further, we explored whether the strength of this relationship varied depending on IPV type (i.e., physical, psychological, sexual, and cyber), and perpetrator gender. Systematic searches of Medline Complete, PsycInfo, Scopus, and Web of Science databases were conducted on July 4, 2023. Studies were included if they were a peer-reviewed published paper or unpublished dissertation, in English, included a measure of Machiavellianism and IPV perpetration, and reported the relationship between these variables. Study quality was assessed using the AXIS tool. Nineteen studies ( N = 9,464) were included in a random-effects meta-analysis revealing a significant, weak, positive correlation between Machiavellianism and IPV perpetration ( r = .16, 95% CI [0.11, 0.21], p < .001). Machiavellianism had a significant, weak, positive relationship with cyber ( r = .25, 95% CI [0.17, 0.32], p < .001), psychological ( r = .20, 95% CI [0.15, 0.24], p < .001), and sexual IPV ( r = .10, 95% CI [0.02, 0.19], p = .020). No significant relationship was found for physical IPV. There was no significant difference in the strength of the relationship between women and men. These findings are limited by the measures being self-report, heterogeneity across studies, and the cross-sectional nature of the included studies which limits the understanding of causal pathways. Nonetheless, this meta-analysis shows a link between Machiavellianism and IPV perpetration, and future research should examine how this knowledge may be used to reduce IPV perpetration.

马基雅维利主义和亲密伴侣暴力实施：系统评价和荟萃分析


本系统评价和荟萃分析估计了马基雅维利主义与亲密伴侣暴力 （IPV） 实施之间的关系大小。此外，我们探讨了这种关系的强度是否因 IPV 类型（即身体、心理、性和网络）和犯罪者的性别而异。2023 年 7 月 4 日对 Medline Complete、PsycInfo、Scopus 和 Web of Science 数据库进行了系统检索。如果研究是同行评审的已发表论文或未发表的英文论文，包括马基雅维利主义和 IPV 犯罪的测量，并报告这些变量之间的关系，则纳入研究。使用 AXIS 工具评估研究质量。19 项研究 （ N = 9,464） 被纳入一项随机效应荟萃分析，揭示了马基雅维利主义与 IPV 犯罪之间存在显著、微弱、正相关 （r = .16， 95% CI [0.11， 0.21]，p < .001）。马基雅维利主义与网络 （r = .25， 95% CI [0.17， 0.32]，p < .001）、心理 （r = .20， 95% CI [0.15， 0.24]，p < .001） 和性 IPV （ r = .10， 95% CI [0.02， 0.19]，p = .020）具有显著、微弱的正相关关系。未发现物理 IPV 存在显著关系。女性和男性之间的关系强度没有显著差异。这些发现受到自我报告措施、研究间异质性以及纳入研究的横断面性质的限制，这限制了对因果途径的理解。尽管如此，这项荟萃分析显示了马基雅维利主义与 IPV 犯罪之间的联系，未来的研究应研究如何利用这些知识来减少 IPV 犯罪。
