Little is known about the factors that facilitate the perpetration of sexual violence within the context of same-sex romantic relationships (sexual intimate partner violence perpetration [S-IPV]). The present study sought to identify the effects of external and internal minority stress and problematic drinking on perpetration of S-IPV within a dyadic framework. A community-based sample of 137 sexual and gender minority (SGM) couples (N = 274; 59 male assigned at birth and 78 female assigned at birth couples) completed self-report surveys about minority stressors, alcohol use, and S-IPV perpetration. Multilevel logistic regression analyses were conducted within an actor-partner interdependence framework. This approach accounted for both actor effects (e.g., how much one's S-IPV perpetration is predicted by their own risk factors) and partner effects (e.g., how much one's S-IPV perpetration is influenced by their partner's risk factors). Both Actor external minority stress and internal minority stress were positively associated with Actor S-IPV perpetration. Actor problematic drinking was not associated with Actor S-IPV perpetration; however, Partner problematic drinking was positively associated with Actor S-IPV perpetration. Observed effects were robust above the addition of other risk factors. This research innovatively extricates S-IPV perpetration from other forms of IPV and indicates that Actor minority stress and Partner problematic drinking increase S-IPV likelihood. Results serve as a starting point for development of etiological models to inform the design of culturally-informed interventions to reduce S-IPV among SGM couples.
关于促进同性浪漫关系中性暴力行为（性亲密伴侣暴力行为[ S-IPV ]）的因素知之甚少。本研究旨在在对偶框架内确定外部和内部少数群体压力以及问题性饮酒对 S-IPV 行为的影响。在一项基于社区的性和性别少数群体（SGM）夫妇样本中（N = 274；59 名男性出生分配和 78 名女性出生分配夫妇），完成了关于少数群体压力源、饮酒和 S-IPV 行为的自我报告调查。在演员-伙伴相互依存框架内进行了多层次逻辑回归分析。这种方法既考虑了演员效应（例如，一个人的 S-IPV 行为是由其自身的危险因素预测的），也考虑了伙伴效应（例如，一个人的 S-IPV 行为是受其伙伴的危险因素影响的）。演员外部少数群体压力和内部少数群体压力均与演员 S-IPV 行为呈正相关。演员问题性饮酒与演员 S-IPV 行为无关；然而，伴侣问题性饮酒与演员 S-IPV 行为呈正相关。观察到的效应在加入其他危险因素后仍然稳健。这项研究创新性地将 S-IPV 行为从其他形式的 IPV 中分离出来，并表明演员少数群体压力和伴侣问题性饮酒增加了 S-IPV 的可能性。研究结果为制定病因学模型提供了起点，为减少 SGM 夫妇中的 S-IPV 提供了文化上知情的干预措施。
