Parenting behaviors are significantly linked to youths' behavioral adjustment, an association that is moderated by youths' and parents' self-regulation. The biological sensitivity to context theory suggests that respiratory sinus arrhythmia (RSA) indexes youths' varying susceptibility to rearing contexts. However, self-regulation in the family context is increasingly viewed as a process of "coregulation" that is biologically embedded and involves dynamic Parent×Child interactions. No research thus far has examined physiological synchrony as a dyadic biological context that may moderate associations between parenting behaviors and preadolescent adjustment. Using a two-wave sample of 101 low-socioeconomic status (SES) families (children and caretakers; mean age 10.28 years), we employed multilevel modeling to examine dyadic coregulation during a conflict task, indicated by RSA synchrony, as a moderator of the linkages between observed parenting behaviors and preadolescents' internalizing and externalizing problems. Results showed that high dyadic RSA synchrony resulted in a multiplicative association between parenting and youth adjustment. High dyadic synchrony intensified the relations between parenting behaviors and youth behavior problems, such that in the context of high dyadic synchrony, positive and negative parenting behaviors were associated with decreased and increased behavioral problems, respectively. Parent-child dyadic RSA synchrony is discussed as a potential biomarker of biological sensitivity in youth.
养育行为与青少年的行为调整密切相关，这种关联受到青少年和家长自我调节能力的调节。生物对环境的敏感性理论表明，呼吸窦性心律失常（RSA）指标反映了青少年对养育环境的不同敏感性。然而，家庭环境中的自我调节越来越被视为一种“共调节”的过程，它具有生物嵌入性，并涉及到动态的父母-孩子相互作用。迄今为止，没有研究探讨过生理同步作为一种可能调节养育行为与青少年适应之间关系的二元生物环境。本研究使用了两波来自低收入家庭（101 个家庭，儿童和照顾者；平均年龄 10.28 岁）的样本，采用多层次模型，考察了冲突任务中的二元共调节情况，即 RSA 同步，作为观察到的养育行为与青少年内化和外化问题之间联系的调节因素。结果表明，高二元 RSA 同步会导致养育行为和青少年适应之间的乘法关联。高二元同步强化了养育行为与青少年行为问题之间的关系，使得在高二元同步的情况下，积极和消极的养育行为分别与行为问题的减少和增加有关。讨论了亲子二元 RSA 同步作为青少年生物敏感性的潜在生物标志物。
