Early parental loss has been associated with neuroendocrine dysregulation in youth; however, the form of cortisol dysregulation varies widely. Identifying risk and protective factors that influence physiological regulation has important implications for understanding the development of mental health problems in parentally bereaved youth.
The current study investigated the prospective effects of positive parenting on the relation between recent negative life events and cortisol activity in adolescents/young adults several years after bereavement.
Positive parenting was assessed an average of 18.5 months following parental death. Six years later, adolescents/young adults (N = 55) reported on exposure to recent negative life events, and salivary cortisol was assessed before and after a conflict discussion task with their caregiver. The interaction between positive parenting and exposure to recent negative events was used to predict total cortisol output and response to the task.
Multilevel modeling and the probing of the interaction effect demonstrated that total cortisol output increased with greater exposure to recent negative events among those with lower levels of past positive parenting. These relations were significant over and above current internalizing and externalizing symptoms.
The current results highlight the need to consider the interactive influence of proximal and distal factors on neuroendocrine functioning for youth exposed to early parental loss.
早期父母丧失与年轻人的神经内分泌失调有关;然而,皮质醇失调的形式差异很大。确定影响生理调节的风险和保护因素对理解父母丧亲的年轻人心理健康问题的发展具有重要意义。
本研究调查了积极的育儿方式对丧亲后几年青少年/年轻人近期负性生活事件与皮质醇活动之间关系的前瞻性影响。
积极的育儿方式在父母去世后平均 18.5 个月进行评估。六年后,青少年/年轻人(N=55)报告了最近的负性生活事件的暴露情况,并在与照顾者进行冲突讨论任务之前和之后测量了唾液皮质醇。积极的育儿方式与最近负性生活事件暴露之间的相互作用用于预测总皮质醇输出和对任务的反应。
多层次模型和相互作用效应的探测表明,在过去积极育儿水平较低的人群中,随着最近负性生活事件的增加,总皮质醇输出增加。这些关系在当前的内化和外化症状之外仍然显著。
目前的结果强调了需要考虑早期父母丧失的青少年暴露于近端和远端因素对神经内分泌功能的相互影响。
