The current study examined a temporal cascade linking mothers' history of abuse with their children's internalizing difficulties through proximal processes such as maternal postnatal depressive symptoms and responsive parenting. Participants consisted of 490 mother-child dyads assessed at three time points when children were, on average, 2 months old at Time 1 (T1), 18 months at Time 2 (T2), and 36 months at Time 3 (T3). Maternal abuse history and depressive symptoms were assessed via questionnaires at T1. Observations of responsive parenting were collected at T2 and were coded using a validated coding scheme. Children's internalizing difficulties were assessed in the preschool period using averaged parental reports. Path analysis revealed that maternal physical abuse was associated with depressive symptoms postnatally, which were in turn associated with children's internalizing behavior at 36 months of age. We also found that the association between physical abuse history and responsive parenting operated indirectly through maternal depressive symptoms. These findings remained after controlling for covariates including socioeconomic status, child gender, and age. After accounting for physical abuse history, sexual abuse history was not associated with child internalizing problems either directly or indirectly through maternal depressive symptoms and/or parenting behavior. Thus, mothers' physical abuse history is a risk factor for relatively poor mental health, which is itself predictive of both later parenting behavior and children's internalizing problems.
本研究通过诸如母亲产后抑郁症状和反应性养育等近端过程,考察了一个将母亲的虐待史与其子女内化问题相联系的时间序列。研究参与者包括490对母婴二元组,在三个时间点进行评估,在时间1(T1)时,孩子平均2个月大;在时间2(T2)时,孩子18个月大;在时间3(T3)时,孩子36个月大。在T1时通过问卷评估母亲的虐待史和抑郁症状。在T2时收集反应性养育的观察数据,并使用经过验证的编码方案进行编码。在学前阶段使用父母平均报告评估孩子的内化问题。路径分析显示,母亲的身体虐待与产后抑郁症状相关,而产后抑郁症状又与孩子36个月大时的内化行为相关。我们还发现,身体虐待史与反应性养育之间的关联通过母亲的抑郁症状间接起作用。在控制了包括社会经济地位、孩子性别和年龄等协变量后,这些结果仍然成立。在考虑了身体虐待史之后,性虐待史无论是直接还是通过母亲的抑郁症状和/或养育行为间接与孩子的内化问题均无关联。因此,母亲的身体虐待史是心理健康相对较差的一个风险因素,而心理健康本身又能预测后期的养育行为和孩子的内化问题。
