Sexual orientation identity and romantic relationship quality in same-sex couples.

Research suggests that the well-being of members of stigmatized groups is related to the ways that individuals understand, evaluate, and respond to their devalued collective identity. The present study extends this line of inquiry by investigating collective identity in the context of romantic relationship functioning, focusing on same-sex couples as a type of stigmatized relationship. In this cross-sectional study, the authors examined four identity-related variables (internalized homonegativity, stigma sensitivity, identity confusion, and identity superiority) in a sample of 274 female and 187 male same-sex couples. Results provided evidence of identity similarity between partners, particularly for internalized homonegativity and identity superiority. Each of the identity variables was associated with relationship quality, and actor effects of identity on quality were more common than partner effects. Perceived identity similarity mediated some of the links found between identity and quality and was positively associated with relationship quality regardless of actor identity.
