Polyamory is a type of consensual non-monogamy (CNM) in which participants engage in multiple simultaneous romantic and often sexual relationships with the knowledge and consent of all involved. CNM practitioners in general, and polyamorous people in specific, appear to be

highly stigmatized due to their relational practices, and to frequently encounter CNM-related discrimination, harassment, and violence (DHV). Conceptualizing this dynamic via minority stress theory predicts that this stigma and DHV will lead to negative mental health outcomes for polyamorous individuals. However, recent research has begun to identify possible sources of resilience and strength within polyamorous populations, which may ameliorate these negative effects, as well as enhance satisfaction with CNM and quality of life.
