母亲在早期环境中的负面影响被认为对儿童的长期应对能力敏感。然而，很少有工作确定与应对反应相关的生理系统，这可能是早期母亲消极情绪与儿童结局之间联系的机制。通过纵向双胞胎样本（N = 89），我们发现婴儿时期高水平的母亲负面影响与皮质醇和脑电图（EEG）不对称的昼夜调节失调有关，这两种生理系统可能支持儿童在7岁时积极的方法导向应对。皮质醇日变化平缓也与儿童同时出现过多的过度焦虑行为有关。一项中介分析支持了昼夜皮质醇失调作为早期环境中母亲负面影响与儿童焦虑问题风险之间联系的中介的作用。(C) 2015爱思唯尔公司版权所有。
Maternal negative affect in the early environment is believed to sensitize long-term coping capacities in children. Yet, little work has identified physiological systems associated with coping responses, which may serve as mechanisms for links between early maternal negativity and child outcomes. Using a longitudinal twin sample (N = 89), we found that high levels of maternal negative affect during infancy were associated with dysregulation of diurnal cortisol and electroencephalograph (EEG) asymmetry, two physiological systems that may support active approach-oriented coping when children are 7 years old. Flattened slopes of diurnal cortisol were also associated with greater numbers of concurrent overanxious behaviors in children. A mediation analysis supported the role of dysregulated diurnal cortisol as a mediator of the link between maternal negative affect in the early environment and childhood risk for anxiety problems.
