Social marginalization increases the risk of suicidal ideation (SI) among individuals with diverse identities, yet research examining the effects of marginalization has focused on one identity. Emerging adulthood is a critical period of identity development and the age group with the highest rates of SI. Considering the challenges of living in potentially heterosexist, cissexist, racist, and sizeist environments, we tested whether possessing multiple marginalized identities was associated with severity of SI through factors proposed in the interpersonal-psychological theory (IPT) and the three-step theory (3ST) of suicide and if mediation paths were moderated by sex. A sample of 265 college students completed a cross-sectional online survey assessing SI and constructs related to IPT and 3ST. The number of marginalized identities was generated by adding minoritized sexual orientation, race/ethnicity other than non-Hispanic White, body mass index >25 kg/m2, sexual attraction to same sex but identified as heterosexual, and gender-fluid identity. In IPT multiple mediation analyses, possessing more marginalized identities was associated with SI severity through burdensomeness and hopelessness, but not belonging. Indirect paths through burdensomeness and belonging were moderated by sex. For 3ST, possessing more marginalized identities was associated with SI severity through hopelessness and psychological pain, but not social connection or meaning in life. Future research should consider intersecting social identities and test mechanisms by which multiply marginalized college students develop resilience to SI risk factors, such as support within their marginalized groups, to inform suicide assessment and intervention efforts on college campuses.

There is currently a lack of measures testing intraminority stress within gay men. Therefore, the current study sought to develop and psychometrically test the Gay-Specific Intraminority Stigma Inventory (G-SISI). Based on a content review of the literature and a panel of experts, a pool of items assessing gay men’s perceived exposure to a range of discriminatory attitudes from other gay men was generated. Utilizing a randomly split sample of 1723 gay men between the ages of 19 and 79 years, an exploratory factor analysis was first performed (n = 861). The remaining unexamined data were then used to conduct a confirmatory factor analysis (n = 862). The results support a six-factor model: (1) Age Stigma, (2) Socioeconomic Stigma, (3) Gay Non-Conformity Stigma, (4) Racial Stigma, (5) Gender Expression Stigma, and (6) Body Stigma. Cronbach’s alpha for the total scale was 0.90 and for the subscales ranged from 0.60 to 0.85. Sociodemographic factors and measures of community involvement were differentially associated with the G-SISI subscales, providing evidence of construct validity. The findings demonstrate initial support for the dimensionality and validity of the G-SISI, which targets modifiable factors (e.g., identity-based stigma) that may increase stress and reduce community coping resources among gay men with diverse identities.

Sexual minoritized individuals engage in non-suicidal self-injury (NSSI) at higher rates than their heterosexual peers. Disclosing one's sexual minoritized identity can put one at risk for experiencing discrimination, which is linked to greater engagement in NSSI. However, discrimination has yet to be tested as a mechanism linking sexual identity disclosure to NSSI. Understanding how sexual identity disclosure impacts NSSI has the potential to inform interventions to reduce sexual orientation disparities in NSSI. To address this gap, the current study examined sexual orientation-based discrimination as a mediator of the longitudinal association between sexual identity disclosure and NSSI among 792 sexual minoritized young adults. Higher levels of disclosure at baseline were associated with greater likelihood of NSSI at two-month follow-up via greater discrimination at one-month follow-up, even after controlling for baseline levels of depression and demographic characteristics. The indirect effect became non-significant after controlling for previous levels of discrimination and NSSI. Findings provide partial support for the hypothesis that identity disclosure may precede exposure to discrimination and, in turn, engagement in NSSI. However, identity disclosure does not appear to predict acute increases in discrimination. Future research is encouraged to examine these prospective associations with longer intervals between assessments, as the indirect effect of identity disclosure on NSSI via discrimination may continue to accumulate over time. Findings highlight the need to reduce discrimination following sexual identity disclosure through the implementation of equitable and affirmative practices in school, healthcare, and other settings to improve the well-being of sexual minoritized young adults.
