The current study investigated actor and partner effects and the effects of (dis)similarity in the dark triad traits on self-reported relationship satisfaction of both members of romantic couples. We examined these effects on actual similarity, similarity of perception, and men's and women's perceived similarity.
On the sample of 205 heterosexual romantic couples, we administered questionnaires for measuring self-reported and partner-reported psychopathy, Machiavellianism, and narcissism, as well as self-reported relationship satisfaction. For analyzing data, we used dyadic response surface analysis.
The results corroborated our hypotheses that the dark triad traits exerted mainly negative actor and partner effects on both partners' relationship satisfaction. The effects of (dis)similarity were obtained for psychopathy and narcissism. Dissimilarity in psychopathy was related to lower men's relationship satisfaction. Dissimilarity in narcissism was related to lower, whereas similarity in this trait to higher relationship satisfaction of both partners. Generally, our findings were similar across methods and sources of assessment.
The results suggest that the DT traits of both members of a romantic couple matter for judgments of their relationship satisfaction and that along with actor and partner effects, the effects of (dis)similarity in psychopathy and narcissism also contribute to their relationship satisfaction.
本研究考察了行为者和伴侣的影响，以及暗黑三因素特质的（不）相似性对浪漫伴侣双方自我报告的关系满意度的影响。我们考察了这些影响在实际相似性、感知相似性以及男性和女性感知相似性上的表现。
在 205 对异性浪漫伴侣的样本中，我们使用问卷测量了自我报告和伴侣报告的精神变态、马基雅维利主义和自恋，以及自我报告的关系满意度。为了分析数据，我们使用了对偶响应面分析。
结果证实了我们的假设，即暗黑三因素特质对双方的关系满意度都有主要的负向行为者和伴侣影响。（不）相似性的影响仅在精神变态和自恋上得到了证实。精神变态的不相似性与男性关系满意度的降低有关。自恋的不相似性与关系满意度的降低有关，而相似性与双方关系满意度的提高有关。总的来说，我们的发现在方法和评估来源上都具有相似性。
研究结果表明，浪漫伴侣双方的 DT 特质对他们关系满意度的判断很重要，并且除了行为者和伴侣的影响外，精神变态和自恋的（不）相似性的影响也对他们的关系满意度有贡献。
