Promoting Consensual Non-Monogamy in Psychological Science, Clinical Practice, and Public Policy: Guidelines for Psychologists

Abstract

Consensual non-monogamy (CNM) encompasses a range of relationship structures in which individuals engage in multiple romantic or sexual relationships with the knowledge and consent of all involved parties. Despite growing visibility and acceptance of CNM relationships, psychological research, clinical practice, and public policy have historically centered on monogamous relationship models, often overlooking the experiences and needs of CNM individuals. This paper examines the importance of integrating consensual non-monogamy into psychological science and professional practice. It reviews current research on relationship satisfaction, mental health, stigma, and interpersonal functioning among CNM populations and highlights common misconceptions that may influence clinical assessment and treatment. The paper further explores ethical and culturally competent approaches for psychologists working with diverse relationship structures. Additionally, it discusses policy implications related to family recognition, healthcare access, and anti-discrimination protections. By promoting evidence-based understanding and inclusive practices, psychologists can contribute to reducing stigma and improving psychological well-being among individuals engaged in consensual non-monogamous relationships. The article concludes with practical guidelines for researchers, clinicians, educators, and policymakers aimed at fostering greater inclusivity, equity, and scientific rigor within the field of psychology.
