Are there "Better" and "Worse" Ways to be Consensually Non-Monogamous (CNM)?: CNM Types and CNM-Specific Predictors of Dyadic Adjustment.

Abstract

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.
