Minority stress and romantic relationship functioning among young sexual minority women.

Abstract

Growing research suggests that minority stress adversely affects relationship functioning among same-gender couples. However, studies have predominantly focused on concurrent, between-persons associations and neglected the relationships sexual minority people have with partners of other genders. We used multiwave longitudinal data from 200 young sexual minority women in relationships with cisgender men, cisgender women, and transgender or nonbinary individuals to assess between- and within-person associations between minority stress and relationship functioning and to test for differences in these associations by partner gender. Participants reported on minority stressors (couple marginalization; microaggressions; internalized heterosexism) and relationship functioning (quality; destructive conflict) from the same partnership at 3-7 assessments (M = 4.44), collected at 6-month intervals. Multilevel models assessing each minority stressor separately revealed between-person associations of each stressor with worse relationship quality and conflict; however, only couple marginalization showed within-person associations with relationship functioning. In multilevel models including all three minority stressors, couple marginalization showed unique within- and between-persons associations with worse relationship functioning; microaggressions were only uniquely associated with couple conflict at the between-persons level. Moderation analyses revealed a negative between-persons association of microaggressions with relationship quality only for participants with cisgender male partners, and a positive within-person association of microaggressions with relationship quality only for those with cisgender female partners. Several associations were weaker for participants with transgender or nonbinary compared to cisgender partners. Findings highlight the importance of couple-level minority stress and partner gender in understanding how sexual minority stress affects relationship functioning.
