OBJECTIVE This study investigated the impact of relational provocation on intimate partner violence (IPV) perpetration as a function of alcohol intoxication and individuals' emotion differentiation (ED; i.e., the ability to differentiate between positive and negative emotions). We hypothesized that provocation and acute intoxication would be associated with lower ED, such that individuals would demonstrate lower ED following provocation and while intoxicated. We also hypothesized an intoxication-by-ED interaction, such that only individuals who were intoxicated and undifferentiated would perpetrate IPV. METHOD Two hundred fifty community-based adults completed an aggression paradigm ostensibly with their romantic partners where they were randomly assigned to an alcohol or no-alcohol condition. Participants' ED across positive and negative subscales was calculated at baseline (Time 1), postprovocation and intoxication (Time 2), and postbehavioral aggression (Time 3). IPV was operationalized as the strength and duration of shocks issued to their partner during the aggression paradigm. RESULTS Both sober and intoxicated participants experienced lower ED following provocation, suggesting a main effect of provocation but no main effect of intoxication. There was a significant alcohol-by-ED interaction in the predicted direction. For intoxicated participants, low ED was associated with greater IPV perpetration. For sober participants, low ED was associated with less IPV perpetration. CONCLUSIONS Consistent with hypotheses, low ED is associated with greater IPV perpetration among intoxicated individuals. In contrast to prior research, low ED was associated with less IPV perpetration among sober individuals. Alcohol-related cognitive impairments may increase the likelihood of IPV perpetration by disrupting the ED process that may otherwise inhibit impulsive aggression.

情绪分化和亲密伴侣暴力：挑衅和酒精中毒的影响。

目的 本研究调查了关系挑衅对亲密伴侣暴力（IPV）实施的影响，作为酒精中毒和个人情绪分化（ED；即区分积极和消极情绪的能力）的函数。我们假设挑衅和急性中毒与较低的 ED 相关，因此个体在挑衅和醉酒时会表现出较低的 ED。我们还假设中毒与 ED 相互作用，这样只有中毒且未分化的个体才会犯下 IPV。方法 250 名社区成年人表面上与他们的浪漫伴侣完成了一个攻击范式，他们被随机分配到饮酒或不饮酒的状态。参与者在阳性和阴性分量表上的 ED 在基线（时间 1）、挑衅和中毒后（时间 2）以及行为攻击后（时间 3）进行计算。IPV 的运作方式是在攻击范式期间向其伴侣发出电击的强度和持续时间。结果 清醒和醉酒的参与者在刺激后的 ED 均较低，这表明刺激有主要影响，但中毒没有主要影响。在预测的方向上存在显着的酒精与 ED 相互作用。对于醉酒的参与者来说，低 ED 与较高的 IPV 发生率相关。对于清醒的参与者来说，低 ED 与较少的 IPV 实施有关。结论 与假设一致，低 ED 与醉酒个体中 IPV 感染率较高相关。与之前的研究相比，低 ED 与清醒个体中较少的 IPV 实施有关。酒精相关的认知障碍可能会扰乱 ED 过程，从而增加 IPV 实施的可能性，否则 ED 过程可能会抑制冲动攻击。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
