We use the Investment Model framework to examine what relationship features are associated with interest in and positive evaluations of consensual non-monogamy (CNM) among individuals in monogamous relationships. In data sets from the United States (Study 1), Europe (Study 2), and Korea (Study 3; total N = 886), perceptions of higher-quality alternatives were consistently associated with more interest in CNM. Further, consistent with previous work on commitment-motivated relationship maintenance processes, we found support for an indirect effect whereby lower commitment was associated with higher perceived attractiveness of alternatives, which in turn was associated with more interest in CNM. The data suggest that the idea of CNM is likely to be most attractive to those who see themselves as having higher-quality relationship options.

选择的质量与建立关系的兴趣呈正相关

我们使用投资模型框架来检查哪些关系特征与一夫一妻制关系中的个人对双方同意的非一夫一妻制 (CNM) 的兴趣和积极评价相关。在来自美国（研究 1）、欧洲（研究 2）和韩国（研究 3；总共N = 886），对更高质量替代品的看法始终与对 CNM 的更多兴趣相关。此外，与之前关于承诺驱动的关系维护过程的工作一致，我们发现支持间接效应，即较低的承诺与更高的替代品吸引力相关，而这反过来又与对 CNM 的更多兴趣相关。数据表明，CNM 的想法可能对那些认为自己拥有更高质量的关系选择的人最具吸引力。
