Sexual minority individuals are at high risk for intimate partner violence (IPV; psychological, physical, sexual) victimization and heavy alcohol use relative. Sexual minority individuals experience several forms of sexual minority stress (SMS; e.g., discrimination, harassment, stigma) that may exacerbate IPV-related stress to enhance risk for alcohol use. This pilot study examined the moderating role of daily SMS in the relationship between IPV victimization and same- and next-day alcohol use among multigender-attracted individuals (e.g., bisexual, pansexual, demisexual) and their partners with minoritized sexual identities. We hypothesized that IPV victimization would positively associate with odds of subsequent alcohol use (# drinks, any drinking), and that greater exposure to daily SMS would strengthen this association.
Eligibility: ≥1 partner must identify as multigender-attracted, 18-30 years old, with at least weekly drinking. Heterosexual partners were not included in these analyses because none reported daily SMS. Participants (N=43 individuals) completed 60 consecutive days of surveys on alcohol use, IPV, and SMS. Participants were primarily white (74.4%), bisexual (46.5%) women (51.2%).
All participants consumed alcohol at least once during the study. There were 159 days of SMS across 29 individuals. To account for the correlated outcomes, we included a random intercept and slope for participant and a random intercept for couple. Daily SMS did not moderate the association between IPV victimization and subsequent alcohol use. A Poisson regression model showed a main effect: experiencing daily SMS associated with an increased rate of drinking by 2.2 times (exp=.78, p < .001). A logistic model examining any drinking post-IPV showed odds of drinking increased by 2.16 times after experiencing SMS (exp=.77, p < .001). With daily SMS in the model, IPV victimization did not associate with odds of subsequent drinking.
Findings support the need for inclusive couple-level interventions that help sexual minority couples manage daily SMS. Community-level interventions that target SMS towards sexual minority individuals may have implications for reducing alcohol use.
