Women higher in psychopathy and more interested in marriage are subjected to more verbal insults by their long-term partner

We investigated whether women (n = 223) higher in the Dark Triad traits (narcissism, psychopathy, Machiavellianism) are subjected to greater cost-inflicting mate retention behaviors by their long-term romantic partners, and we considered women's desire for marriage as a moderator. We found that women higher in narcissism reported lower levels of verbal insults associated with “derogating value as a person” inflicted by their partners. Women higher in psychopathy reported higher levels of verbal insults associated with derogating physical attractiveness, derogating value as a partner, accusations of sexual infidelity, and general cost-inflicting mate retention behaviors inflicted by their partners. Women higher in psychopathy and who also reported a higher desire for marriage were subjected to more cost-inflicting mate retention behaviors than women higher in psychopathy that reported a lower desire for marriage. In this context, mate retention behaviors may reduce the likelihood of infidelity by decreasing the self-worth of women higher on the Dark Triad traits so that they conclude they are unable to compete successfully for other partners.
