Decades of research has identified alcohol use as a contributing cause of intimate partner aggression (IPA) perpetration; however, there have been fewer studies that seek to identify mediators of the relation between alcohol use and IPA perpetration. Building on research showing a positive association between problematic drinking and relationship dissatisfaction and relationship dissatisfaction and IPA, we examined whether relationship dissatisfaction accounted for the relation between problematic drinking and IPA perpetration in couples using statistical modeling that accounted for the interdependence between partners. Our results showed that (a) actor problematic drinking was related to actor psychological and physical IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, (b) partner problematic drinking was related to actor physical and psychological IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, and (c) partner problematic drinking was related to actor psychological IPA perpetration and that this relation was partially explained by partner relationship dissatisfaction. Together, our results highlight that when partner interdependence is considered, relationship dissatisfaction could be a potential mechanism of the alcohol-IPA association and provide some evidence for different pathways for psychological and physical aggression.

与酒精相关的关系不满：亲密伴侣攻击的假定机制。

数十年的研究已确定饮酒是亲密伴侣攻击行为 (IPA) 的一个重要原因；然而，很少有研究试图找出饮酒与吸食异丙醇之间关系的中介因素。基于显示问题饮酒与关系不满以及关系不满与 IPA 之间存在正相关关系的研究，我们利用解释伴侣之间相互依赖性的统计模型，研究了关系不满是否解释了夫妻问题饮酒与 IPA 行为之间的关系。我们的结果表明，(a) 演员有问题的饮酒与演员心理和身体的 IPA 实施有关，并且这种关系部分可以通过演员关系不满意来解释，(b) 伴侣有问题的饮酒与演员的身体和心理 IPA 实施有关，并且这种关系(c) 伴侣有问题的饮酒与演员心理 IPA 的实施有关，并且这种关系部分是由伴侣关系不满解释的。总之，我们的结果强调，当考虑伴侣相互依赖时，关系不满可能是酒精-IPA关联的潜在机制，并为心理和身体攻击的不同途径提供了一些证据。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
