Abstract: Research has consistently shown mental health differences between sexual minority subgroups with bisexual people often reporting higher levels of psychological distress than lesbians and gay men. Relationship status has been suggested, but not well studied, as a potential factor contributing to subgroup differences in mental health. Using a national probability sample of nontransgender sexual minority adults across three age cohorts (18–25, 34–41, 52–59 years), we assessed group differences in psychological distress (Kessler 6) between lesbian/gay (N = 505), bisexual (N = 272), and queer/pansexual (N = 75) respondents. We examined whether relationship status (single/partnered) moderated the relationship between sexual identity and psychological distress. Among those that were partnered, we tested whether key partner characteristics related to sexual identity—gender of partner (cisgender same-sex/transgender or cisgender different-sex) and partner sexual identity (same or mixed sexual orientation relationship)—were significantly associated with psychological distress. In bivariate analyses, bisexual and queer/pansexual respondents reported more psychological distress than gay/lesbian respondents, among both men and women. In multivariable analyses, there was not a significant main effect of sexual identity, but there was a significant interaction between sexual identity and partnership status on psychological distress among women. Specifically, while there were no significant differences in psychological distress between subgroups of single women, among partnered women, queer/pansexual women had more distress than lesbian/gay women. Further, partnership was associated with reduced distress among lesbian/gay women, but not among bisexual or queer/pansexual women. Among men, there were no significant interaction effects between sexual identity and partnership status on psychological distress. Being in a mixed orientation relationship, but not gender of partner, was a significant predictor of psychological distress among both women and men across sexual identities. Additional research should assess the partnership dynamics contributing to the association between partnership characteristics and mental health among sexual minority populations.
