Sexual Victimization Among Gay and Bisexual Emerging Adult Men: Multivariate Differences in Substance Use, Minority Stress and Relationship Characteristics.

This study documented between-group differences in factors associated with lifetime sexual victimization in a sample of young sexual minority men. Diverse samples of gay (<italic>N</italic> = 205, ageM = 24.33 years) and bisexual (<italic>N</italic> = 201, ageM = 23.31 years) men were recruited using the CloudResearch platform to assess recent experiences of intimate partner violence (IPV). Participants were categorized into four groups, cross-classified by dichotomous self-reports of (a) childhood sexual abuse (CSA) and (b) sexual IPV. Principal components analysis was used to reduce the number of variables associated with sexual IPV in three domains: Past-year substance use involvement, minority stress, and relationship characteristics, separately for each sample. Gay men reporting both CSA and sexual IPV reported significantly higher mean factor scores for a principal component with high loadings for recent substance use, daily discrimination, relational aggression and relational victimization, compared to other groups of gay men. Bisexual men who experienced sexual IPV reported significantly higher mean factor scores for a principal component with high loadings for five measures of minority stress, compared to counterparts with no history of sexual victimization. Adult sexual IPV among gay men reporting CSA appears to occur in conditions that include harmful substance use, daily discrimination experiences, and relationship violence. Sexual IPV among bisexual men is associated with multiple minority stressors. Our findings highlighted different patterns of risk factors for sexual IPV among sexual minority men, providing information for tailored risk reduction initiatives, including the need for trauma-informed services and specialized training for service providers.
