Adverse childhood experiences (ACEs) are associated with intimate partner violence (IPV) perpetration. A posited mechanism explaining the link between ACEs and IPV is alcohol use consequences. Yet, few studies have examined this relationship among sexual minority young adults or how chronic and unique discrimination due to their marginalized identity (i.e., minority stress) may influence these associations. This study examined whether alcohol use consequences mediated the relationship between ACEs and IPV perpetration, and whether minority stress moderated this mediated relationship. Sexual minority young adults who used alcohol in the past month ( N = 344; age 18–25) in a dating relationship completed a survey on ACEs, IPV, alcohol and minority stress. We hypothesized: (a) alcohol use consequences would mediate the association between ACEs and IPV perpetration and (b) higher discrimination would moderate the mediation of alcohol use consequences in the relationship between ACEs and IPV perpetration. ACEs ( B = 0.74, p = .010) and alcohol use consequences ( B = 0.64, p = .007), were significantly associated with psychological, but not physical, IPV perpetration. Alcohol use consequences did not mediate the association between ACEs and any IPV type. In addition, everyday discrimination was not a significant moderator. ACEs and alcohol use consequences contribute to the risk for IPV perpetration among sexual minority young adults. Future research is needed to determine how alcohol use consequences may impact risk for IPV perpetration among those who have experienced ACEs.

性少数年轻人的不良童年经历和亲密伴侣暴力：酒精后果和歧视的作用


不良童年经历（ACE）与亲密伴侣暴力（IPV）的实施有关。解释 ACE 和 IPV 之间联系的一个假设机制是饮酒后果。然而，很少有研究探讨性少数年轻人之间的这种关系，或者由于他们的边缘化身份（即少数群体压力）而导致的长期和独特的歧视如何影响这些关联。这项研究检验了饮酒后果是否介导了 ACE 和 IPV 实施之间的关系，以及少数群体压力是否调节了这种介导关系。过去一个月在约会关系中饮酒的性少数年轻人（N = 344；年龄 18-25）完成了一项关于 ACE、IPV、酒精和少数群体压力的调查。我们假设：(a) 饮酒后果会调节 ACE 与 IPV 实施之间的关联，(b) 较高的歧视程度会调节酒精使用后果在 ACE 与 IPV 实施之间的关系中的调节。 ACE（B = 0.74，p = .010）和饮酒后果（B = 0.64，p = .007）与 IPV 实施的心理而非身体显着相关。饮酒后果并不介导 ACE 与任何 IPV 类型之间的关联。此外，日常歧视并不是一个重要的调节因素。 ACE 和饮酒后果会增加性少数年轻人感染 IPV 的风险。未来的研究需要确定酒精使用后果如何影响经历过 ACE 的人的 IPV 实施风险。
