The impact of early physical and sexual abuse (EPA/SA) occurring in the first 5 years of life was investigated in relation to depressive and internalizing symptomatology and diurnal cortisol regulation. In a summer camp context, school-aged maltreated (n = 265) and nonmaltreated (n = 288) children provided morning and late afternoon saliva samples on 5 consecutive days. Child self-report and adult observer reports of child internalizing and depressive symptoms were obtained. Children experiencing EPA/SA and high depressive or internalizing symptoms uniquely exhibited an attenuated diurnal decrease in cortisol, indicative of neuroendocrine dysregulation. These results were specific to EPA/SA rather than later onset physical or sexual abuse or early occurring neglect or emotional maltreatment.
本研究旨在探讨儿童生命早期(0-5 岁)遭受的身体虐待和性虐待(EPA/SA)对其抑郁和内化症状以及日间皮质醇调节的影响。研究采用夏令营模式,共纳入 265 名受虐待儿童和 288 名未受虐待儿童,在连续 5 天的时间内,分别于早间和傍晚采集唾液样本。同时,采用儿童自评和成人观察报告评估儿童的内化和抑郁症状。结果发现,经历 EPA/SA 且同时存在高抑郁或内化症状的儿童表现出皮质醇日间下降幅度减弱,提示其存在神经内分泌失调。这些结果与 EPA/SA 有关,而与后期发生的身体或性虐待、早期发生的忽视或情感虐待无关。
