Stress and Relationship Functioning in Same-Sex Couples: The Vulnerabilities of Internalized Homophobia and Outness

ObjectiveWe examined whether high levels of internalized homophobia and low levels of openness about one's sexual identity (outness) were enduring vulnerabilities for same-sex couples' relationship functioning. BackgroundThe vulnerability-stress-adaptation (VSA) model describes how stress can impact relationship functioning. This model has predominately been applied to the study of heterosexual couples, which leaves a dearth of literature on enduring vulnerabilities specific to same-sex couples' relationship functioning. MethodDyadic longitudinal data from a convenience sample of 81 same-sex couples were collected. Internalized homophobia and outness were assessed at baseline followed by 14-day daily diaries assessing external stress and relationship functioning (i.e., severity of conflict, relationship quality, and commitment). Hypotheses were tested using longitudinal actor-partner interdependence models and multilevel modeling. ResultsOn days that individuals with high (but not low) levels of internalized homophobia reported greater daily stress, they also reported greater severity of conflict and poorer relationship quality. On days that individuals with low (but not high) outness had a partner report greater daily stress, the individual reported lower commitment. ConclusionHypotheses were partially supported; high levels of internalized homophobia and low outness were shown to be potential enduring vulnerabilities for individuals in a same-sex relationship. ImplicationsHelping same-sex couples cope with their own and their partner's daily stress, as well as working to decrease internalized homophobia while increasing openness about their sexuality, may help to promote relational functioning.
