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.

皮质醇调节参加优质儿童保育的学龄前儿童的身体同伴受害与身体攻击之间的关系:各知情者的易感性差异证据

摘要:我们研究了通过多信息分析方法(直接观察,教师报告和父母报告)的素质-压力模型或差异敏感性模型是否更好地说明了皮质醇在身体同伴受害与身体攻击之间的关系中的调节作用。 198名接受高质量儿童保育的学龄前儿童。在控制家庭收入,每周托儿时数和儿童年龄的影响后,我们发现我们的结果支持了对男孩的敏感性差异,而对女孩却没有。这种影响在记者内部(观察者和父母的报告)和记者之间(父母报告的受害情况和教师的侵略性)都得到了复制,但仅限男孩。在同伴受害程度较高的情况下,较低水平的基础皮质醇与较高水平的身体攻击性相关,但是,在较低的同伴受害水平下,较低水平的基础皮质醇与较低水平的身体攻击性相关。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性相关,但在较低的同伴受害水平下,较高的基础皮质醇水平与较高的身体攻击性相关。这些结果突显了幼儿期社会环境与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。较低水平的基础皮质醇与较低水平的身体攻击性相关。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性相关,但在较低的同伴受害水平下,较高的基础皮质醇水平与较高的身体攻击性相关。这些结果突显了幼儿期社会环境与生物行为系统之间复杂的相互作用,以及在同伴关系研究中考虑差异易感性框架的价值。较低水平的基础皮质醇与较低水平的身体攻击性相关。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性相关,但在较低的同伴受害水平下,较高的基础皮质醇水平与较高的身体攻击性相关。这些结果突显了幼儿期社会环境与生物行为系统之间复杂的相互作用,以及在同伴关系研究中考虑差异易感性框架的价值。较高水平的基础皮质醇与较高水平的身体攻击相关。这些结果突显了幼儿期社会环境与生物行为系统之间复杂的相互作用,以及在同伴关系研究中考虑差异易感性框架的价值。较高水平的基础皮质醇与较高水平的身体攻击相关。这些结果突显了幼儿期社会环境与生物行为系统之间复杂的相互作用,以及在同伴关系研究中考虑差异易感性框架的价值。
