Research on consensual non-monogamy (CNM) has largely been restricted to comparisons between monogamous and CNM people, with researchers paying little attention to various CNM styles. The current research elucidated differences among three styles of CNM: open relationships, polyamory, and swinging. Across three studies, we demonstrated that people in polyamorous or swinger-style relationships have higher levels of relationship satisfaction and other relational outcomes (e.g., passionate love, trust) than those in open relationships. That is, people in open relationships consistently fared more poorly in their relational outcomes than those in other types of CNM relationships. In Studies 4 and 5, we isolated some of the reasons for these differences. We found that differences in relational outcomes between open-style and other styles of CNM dissipated when controlling for (a) couples' approach to communication, (b) extrinsic versus intrinsic motivations for participating in CNM, (c) adherence to pro-monogamy beliefs and (d) degree of contact with one's partner's partners ("metamours"). Thus, CNM-specific relational dynamics are associated with dyadic adjustment in these relationships.
对双方自愿非一夫一妻制（CNM）的研究主要局限于对一夫一妻制者和CNM者的比较，研究人员很少关注各种CNM形式。当前的研究阐明了三种CNM形式之间的差异：开放式关系、多配偶制和交换伴侣。在三项研究中，我们证明，处于多配偶制或交换伴侣式关系中的人比处于开放式关系中的人有更高水平的关系满意度和其他关系结果（如热烈的爱情、信任）。也就是说，处于开放式关系中的人在关系结果方面始终比处于其他类型CNM关系中的人表现更差。在研究4和研究5中，我们找出了造成这些差异的一些原因。我们发现，当控制以下因素时，开放式与其他形式的CNM在关系结果上的差异会消失：（a）伴侣的沟通方式，（b）参与CNM的外在动机与内在动机，（c）对一夫一妻制信念的坚持，以及（d）与伴侣的伴侣（“情人的情人”）的接触程度。因此，特定于CNM的关系动态与这些关系中的二元调整相关。
