这项多方法的纵向研究评估了母亲敏感的父母教养方式的变化如何作为联系家庭不稳定和儿童外化问题随时间发展的间接因素。这项研究还调查了母亲在交感神经系统(SNS)中的应激反应如何缓和家庭不稳定与母亲敏感性发展之间的联系。研究对象是235个有小孩的家庭(第一次测量时MAGE=2.97岁)，并对这些家庭进行了两次年度测量。母亲在两个学科任务(即禁用玩具和学科讨论任务)中观察到了母亲的敏感性，母亲的SNS应激反应是通过她们对人际应激源的唾液α-淀粉酶(SaA)反应来指示的。研究结果显示，家庭不稳定和家庭不稳定-x-SAA反应性相互作用与母亲的敏感度随时间的变化有关，具有显著的直接影响。在这两项任务中，SAA反应性较强的母亲表现出家庭不稳定与其敏感度增长之间更强的关联。对间接影响的检验表明，母亲敏感度的变化是家庭不稳定--x-SaA反应性相互作用和儿童外化问题变化之间的间接因素。本研究结果对于理解与不稳定的家庭环境相关的父母和儿童后遗症具有重要的意义。
This multi-method longitudinal study evaluated how changes in maternal sensitive parenting may operate as an indirect factor linking family instability and the development of child externalizing problems over time. This study also investigated how mothers’ stress reactivity within the sympathetic nervous system (SNS) may moderate the association between family instability and the development of maternal sensitivity. Participants were 235 families with a young child (Mage = 2.97 years at the first measurement occasion) and these families were followed for two annual measurement occasions. Maternal sensitivity was observed during two discipline tasks (i.e., forbidden toy, discipline discussion tasks), and maternal SNS stress reactivity was indicated by their salivary alpha-amylase (sAA) reactivity to an interpersonal stressor. Findings revealed significant direct effects of family instability and family instability-x-sAA reactivity interaction in association with the change in maternal sensitivity over time. For both tasks, mothers with greater sAA reactivity exhibited stronger associations between family instability and the growth of their sensitivity. Tests of indirect effects indicated that change in maternal sensitivity operated as an indirect factor between family instability-x-sAA reactivity interaction and the change in child externalizing problems. The present findings have important implications for understanding parental and child sequelae associated with unstable family contexts.
