Objective Previous research has demonstrated a significant association between trauma and intimate partner aggression (IPA) perpetration. However, the precise mechanisms underlying this relationship have yet to be fully elucidated. In the present study, we examined the impact of several key factors implicated in Ehlers and Clark's (2000) cognitive model of trauma (i.e., trauma cognitions, anger, hostility, and rumination) on IPA perpetration. Method Participants in this study were 271 male and female heavy drinkers at high risk for IPA from the community who completed measures of dysfunctional posttraumatic cognitions, dispositional rumination, trait anger and hostility, and IPA perpetration. A moderated mediational model was tested to determine how these variables interact to predict IPA perpetration. Results Results indicated that anger and hostility mediated the effect of negative cognitions about the world on IPA perpetration, with this indirect effect being stronger for individuals with higher levels of rumination. Conclusion These findings suggest that cognitive and affective processes that may result from trauma exposure are associated with IPA and should be targeted in prevention and intervention programs for individuals at risk for perpetration.

创伤认知和伴侣攻击：作为干预机制的愤怒、敌意和反省。

目标 先前的研究表明，创伤与亲密伴侣攻击 (IPA) 行为之间存在显着关联。然而，这种关系背后的确切机制尚未完全阐明。在本研究中，我们研究了 Ehlers 和 Clark (2000) 的创伤认知模型（即创伤认知、愤怒、敌意和反刍）中涉及的几个关键因素对 IPA 实施的影响。方法 本研究的参与者是来自社区的 271 名 IPA 高危男性和女性酗酒者，他们完成了功能失调的创伤后认知、性格反刍、特质愤怒和敌意以及 IPA 实施的测量。测试了一个有调节的中介模型，以确定这些变量如何相互作用以预测 IPA 的实施。结果 结果表明，愤怒和敌意介导了对世界的负面认知对 IPA 犯罪的影响，这种间接影响对于反刍水平较高的个体更强。结论 这些研究结果表明，可能由创伤暴露引起的认知和情感过程与 IPA 相关，应针对有犯罪风险的个人进行预防和干预计划。
