The Roles of Identity Centrality and Affirmation in the Associations Between Discrimination and Mental Health Among Bi+ Adults

Bi+ individuals are at increased risk for mood and anxiety disorders compared to heterosexual and lesbian/gay individuals in part due to unique experiences of discrimination. Minority stress theory posits that associations between discrimination and adverse mental health outcomes may be stronger for those with higher identity centrality and lower identity affirmation, but few studies have tested these hypotheses. Therefore, the current study examined whether identity centrality and affirmation moderated the associations between discrimination and depression and anxiety symptoms among 715 bi+ adults. In bivariate analyses, discrimination was positively associated with depression and anxiety symptoms, whereas identity centrality and affirmation were not significantly associated with either. However, in multivariate analyses, identity centrality and affirmation were negatively associated with depression and anxiety symptoms, respectively. Neither identity centrality nor affirmation moderated any associations. These findings raise the question whether identity characteristics moderate associations between discrimination and mental health, but replication is needed.
