Consensually non-monogamous (CNM) romantic and sexual relationships tend to be stigmatized. The present research examined this stigma across two studies. First, we qualitatively explored the specific ways that people in CNM relationships report experiencing stigma using thematic analysis and identified the following four themes: Expressions of discomfort/disapproval of CNM, Loss of resources/threatening behaviors, Character devaluation, and Relationship devaluation (Study 1; N = 372). Second, we examined the relationship between experienced stigma and psychological well-being for people in CNM relationships, using the framework of minority stress theory. We found that experienced stigma was positively associated with psychological distress and that this association was partially statistically mediated by anticipated stigma and internalized stigma (Study 2; N = 383). Overall, this research strives to achieve a better understanding of the processes and potential consequences of stigma toward CNM relationships and individuals.
