童年被忽视的父母的后代出现内化问题的风险更高。经验证据表明，这种联系主要是通过父母行为来调解的。然而，在许多家庭中，这种逆境的代际循环被打破了。副交感神经系统的功能在生物学上调节个体的情绪调节。呼吸窦性心律失常（RSA）是副交感神经活动的有效生物标志物。本研究的目的是探讨父母RSA反应在父母童年忽视对儿童内化问题的影响中，通过父母接受的调节作用。生理和调查数据来自145对夫妇（94%为母亲；YouthMage= 12.9, YouthSDage= 0.85）。结果表明，父母童年忽视对儿童内化问题的影响取决于父母的RSA反应。具体来说，如果父母表现出缺乏RSA戒断，父母的忽视程度越高，青少年内化问题的风险就越高。此外，这种调节效应被发现是通过父母的接受介导的。研究结果表明，理解儿童虐待背景的代际后果应包括考虑生物调节因素。
Offspring of parents who experienced childhood neglect are at increased risk for developing internalizing problems. Empirical evidence suggests this link is principally mediated through parenting behavior. However, such intergenerational cycles of adversity are found to be disrupted in many families. Parasympathetic nervous system functioning is well documented to mediate individuals’ emotion regulation biologically. Respiratory sinus arrhythmia (RSA) is a validated biomarker for parasympathetic activity. The goal of the current study was to investigate the moderating role of parent RSA reactivity in the effect of parents’ childhood neglect on their children’s internalizing problems, through parental acceptance. Physiological and survey data were collected from 145 dyads (94% mothers; YouthMage= 12.9, YouthSDage= 0.85). Results suggest that the effect of parents’ childhood neglect on their child’s internalizing problems was conditional on parents’ RSA reactivity. Specifically, higher levels of parents’ neglect were only linked to increased risk for youth internalizing problems if parents exhibited a lack of RSA withdrawal. Further, this moderating effect was found to be mediated through parental acceptance. Findings suggest understanding intergenerational consequences of child maltreatment contexts should include consideration of bioregulatory factors.
