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.
目的
先前的研究表明创伤与亲密伴侣攻击行为（IPA）之间存在显著关联。然而，这种关系背后的确切机制尚未完全阐明。在本研究中，我们考察了埃勒斯和克拉克（2000年）创伤认知模型中涉及的几个关键因素（即创伤认知、愤怒、敌意和沉思）对IPA行为的影响。
方法
本研究的参与者是来自社区的271名有IPA高风险的男女重度饮酒者，他们完成了创伤后功能失调认知、特质沉思、特质愤怒和敌意以及IPA行为的测量。测试了一个调节中介模型，以确定这些变量如何相互作用来预测IPA行为。
结果
结果表明，愤怒和敌意介导了对世界的负面认知对IPA行为的影响，对于沉思水平较高的个体，这种间接影响更强。
结论
这些发现表明，创伤暴露可能导致的认知和情感过程与IPA有关，应该在针对有实施风险个体的预防和干预项目中作为目标。
