Although a cycle of harsh and abusive parenting has been recognized for decades, this cycle is not inevitable. Indeed, the mechanisms underlying such patterns, and the resources parents may access to disrupt this cycle, require further study. Research investigating those processes has either relied on cross-sectional designs or largely assessed mediators or moderators at one time point. The current investigation of parent-child aggression (PCA) risk utilized a longitudinal design to consider possible mediators and moderators across three time points. Mothers and fathers reported on their personal history of physical and psychological abuse during the last trimester of the mother's pregnancy; their PCA risk was assessed concurrently when their child was 6 months and when their child was 18 months. Current findings support several mediators for mothers, although fewer for fathers, prenatally, but mediation was not observed across time. Similarly, several moderators of the effect of personal history of physical and psychological aggression on PCA risk were identified prenatally but not across time. Thus, several qualities believed to account for, or mitigate, the intergenerational transmission of PCA may not be consistent-underscoring the continued need to identify factors that account for the cyclical process versus what may interrupt intergenerational transmission.
尽管数十年前就已经认识到了恶劣和虐待性的养育循环，但这种循环并非不可避免。实际上，这种模式的潜在机制以及父母可以用来打破这种循环的资源需要进一步研究。研究这些过程的研究要么依赖于横断面设计，要么主要在一个时间点评估中介或调节因素。目前对亲子攻击（PCA）风险的调查利用纵向设计，在三个时间点上考虑可能的中介和调节因素。母亲和父亲在母亲怀孕的最后三个月报告了他们个人的身体和心理虐待史；当他们的孩子 6 个月大时和孩子 18 个月大时，他们的 PCA 风险同时得到评估。目前的研究结果支持了母亲在产前有几个中介因素，但父亲的中介因素较少，但在整个时间内没有观察到中介作用。同样，在产前确定了个人身体和心理攻击史对 PCA 风险的几个调节因素，但不是在整个时间内。因此，一些被认为可以解释或减轻 PCA 代际传递的特征可能不一致，这突显了继续确定解释循环过程的因素的必要性，而不是可能中断代际传递的因素。
