Participants were young adult heterosexual dating couples. The effects of similarity in the DT traits on RQ were somewhat different depending on different methods used as well as whether we considered women or men's RQ.
PRA showed that dissimilarity in psychopathy was related to lower women's RQ, while similarity at high levels of Machiavellianism to lower RQ in women and men. Additionally, women's RQ decreased more sharply when partners were similar at high levels of Machiavellianism.
PS in narcissism was associated with higher RQ in women and men. This study suggests that different methods of assessment of dis similarity could add to the more thorough understanding of the associations between personality traits and relationship outcomes. Although the Dark Triad traits -narcissism, Machiavellianism, and psychopathy -have been studied in individuals, little is known about their roles in dating relationships.
Within couples, assortative mating was slightly negative for narcissism, marginally positive for Machiavellianism, and significantly positive for psychopathy. Using actor-partner interdependence models, we explored the extent to which satisfaction mediated the direct associations between the Dark Triad and commitment. Men's satisfaction marginally mediated the women's Dark Triad? Among the three Dark Triad subscales, satisfaction marginally mediated both of the actor-effect-based psychopathy?
