Cross-sectional research has suggested that posttraumatic stress disorder (PTSD) symptom severity may be an important predictor of family violence perpetration; however, causal inference is limited by the absence of studies designed to prospectively predict family violence by PTSD symptoms. In the current study, PTSD symptoms were assessed among 250 trauma-exposed heterosexual couples 10 months after having their 1st child. The number of acts of psychological and physical intimate partner aggression (IPA) and parent-to-child aggression (PCA) that occurred during the past year was assessed at 10 and 24 months postpartum to account for stability in family violence perpetration when prospectively predicting perpetration. Longitudinal actor-partner interdependence models revealed that women's and men's PTSD symptoms positively predicted increases in the frequency of their own perpetration of psychological and physical IPA as well as psychological PCA. Additionally, partners' PTSD symptoms prospectively predicted psychological and physical IPA perpetration but not psychological or physical PCA perpetration, suggesting that partners' PTSD symptoms may directly impact dyadic processes during incidents of IPA but may not generally affect the family environment in a way that potentiates all forms of aggression. No significant gender differences were revealed. Overall, results of the current study largely support existing research and theory while clarifying inconsistencies that have emerged when examining cross-sectional associations. Further, the current results highlight the potential utility of PTSD treatment as an avenue for aggression prevention and intervention efforts during the early parenting years.

横断面研究表明，创伤后应激障碍（PTSD）症状严重程度可能是家庭暴力行为的一个重要预测因素；然而，由于缺乏旨在通过 PTSD 症状前瞻性预测家庭暴力的研究，因果推理受到限制。在当前的研究中，在孩子出生后 10 个月，对 250 对经历过创伤的异性恋夫妇进行了 PTSD 症状评估。在过去一年中，心理和身体上的亲密伴侣侵犯（IPA）和父母对孩子的侵犯（PCA）的行为次数在产后 10 个月和 24 个月进行了评估，以说明当前瞻性预测侵犯行为时，家庭暴力行为的稳定性。纵向演员-伙伴相互依存模型显示，女性和男性的 PTSD 症状与自身心理和身体 IPA 以及心理 PCA 侵犯频率的增加呈正相关。此外，伴侣的 PTSD 症状前瞻性预测心理和身体 IPA 的侵犯行为，但不预测心理或身体 PCA 的侵犯行为，这表明伴侣的 PTSD 症状可能直接影响 IPA 事件期间的二元关系过程，但通常不会以增强所有形式侵犯的方式影响家庭环境。没有发现显著的性别差异。总的来说，当前研究的结果在很大程度上支持了现有研究和理论，同时澄清了在检查横断面关联时出现的不一致。此外，当前的结果强调了 PTSD 治疗作为在早期育儿期间预防和干预侵犯行为的一种潜在途径的潜力。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
