Abstract

Abstract:We examined whether the moderating role of cortisol in the relation between physical peer victimization and physical aggression was better accounted for by a diathesis–stress model or a differential susceptibility model using a multiinformant approach (direct observations, teacher reports, and parent reports) of 198 preschool-aged children attending high-quality child care. Controlling for the influence of household income, hours per week in child care, and child age, we found that our results supported a differential susceptibility effect for boys but not for girls. This effect was replicated within reporters (observer and parent reports) and across reporters (parent-reported victimization and teacher-rated aggression) but for boys only. At higher levels of peer victimization, lower levels of basal cortisol were associated with higher levels of physical aggression, but, at lower levels of peer victimization, lower levels of basal cortisol were associated with lower levels of physical aggression. Furthermore, at higher levels of peer victimization, higher levels of basal cortisol were associated with lower levels of physical aggression, but, at lower levels of peer victimization, higher levels of basal cortisol were associated with higher levels of physical aggression. These results highlight the complex interplay between the social environment and biobehavioral systems in early childhood and the value of considering a differential susceptibility framework in peer-relations research.
皮质醇调节参加高质量托儿服务的学龄前儿童同伴伤害和身体攻击之间的关系:不同被调查者易感程度差异的证据
摘要:我们使用多信息者方法(直接观察、教师报告和家长报告)对198名接受高质量儿童护理的学龄前儿童进行了研究,研究了皮质醇在同伴身体伤害和身体攻击之间关系中的调节作用是否可以通过素质-压力模型或差异易感性模型更好地解释。在控制家庭收入、每周儿童保育时间和儿童年龄的影响后,我们发现我们的结果支持男孩的差异易感性效应,但不支持女孩。这种影响在记者(观察者和家长报告)和记者(家长报告的受害情况和教师评定的攻击性)中都有复制,但仅针对男孩。在较高的同伴受害水平下,较低水平的基础皮质醇与较高水平的身体攻击性有关,但在较低的同伴受害程度上,较低的基础皮质醇水平与较低的身体攻击水平有关。此外,在较高的同伴受害水平下,较高的基础皮质醇水平与较低的身体攻击水平有关,但在较低的同伴受害程度下,较高水平的基础皮质醇与较高水平的身体攻击有关。这些结果突出了儿童早期社会环境和生物行为系统之间的复杂相互作用,以及在同伴关系研究中考虑差异易感性框架的价值。
