Internalized Homophobia and Relationship Quality among Same-Sex Couples: The Mediating Role of Intimate Partner Violence.

Based on a geographically and socioeconomically diverse sample of 144 same-sex couples and using a dyadic approach (i.e., the Actor-Partner Interdependence Mediation Model [APIMeM] with interchangeable dyads), this study examined the association between internalized homophobia and same-sex relationship quality, and also tested the potential mediating role of intimate partner violence perpetration in this association. Results indicated that individuals' own and their partners' psychological violence perpetration mediated the negative associations from individuals' own internalized homophobia to individuals' own and their partner's relationship quality. Such findings contribute to the understanding of mechanisms underlying the harmful effects of sexual minority stressors for same-sex relationship well-being. Implications for interventions were also discussed.
