Couple-Level Minority Stress and Mental Health among People in Same-Sex Relationships: Extending Minority Stress Theory

We simultaneously examined the effects of individual- and couple-level minority stressors on mental health among people in same-sex relationships. Individual-level minority stressors emerge from the stigmatization of sexual minority individuals; couple-level minority stressors emerge from the stigmatization of same-sex relationships. Dyadic data from 100 same-sex couples from across the United States were analyzed with actor–partner interdependence models. Couple-level stigma was uniquely associated with nonspecific psychological distress, depressive symptomatology, and problematic drinking, net the effects of individual-level stigma and relevant sociodemographic controls. Analyses also show that couple-level minority stress played unique roles in critical stress processes of minority stress proliferation: minority stress expansion and minority stress contagion. The inclusion of couple-level stress constructs represents a useful extension of minority stress theory, enriching our capacity to deepen understandings of minority stress experience and its application in the study of well-being and health inequalities faced by vulnerable populations.
