Parent-child coregulation is thought to be an important precursor for children's developing self-regulation, but we know little about how individual parent factors shape parent-child physiological coregulation. We examined whether maternal baseline respiratory sinus arrhythmia (RSA), teaching, and disengagement were associated with stronger or weaker coregulation of RSA between mothers and their 3-year-old children (N = 47), modeled across 18 min of observed dyadic interaction using multilevel coupled autoregressive models. Whereas greater maternal teaching was associated with stronger coregulation in mother and child RSA over time, maternal disengagement was related to weaker coregulation, specifically more divergent parent and child RSA at higher levels of maternal disengagement. Coregulation of mother-child RSA was also weaker when mothers' baseline RSA was higher. Findings contribute to the emerging knowledge base on real-time patterns of parent-child physiological coregulation in early childhood and suggest that mothers' physiology and behavioral engagement with the child play an important role in mother-child physiological coregulation patterns.
亲子共同调节被认为是儿童自我调节发展的重要先兆，但我们对个体父母因素如何塑造亲子生理共同调节知之甚少。我们研究了母亲的基线呼吸性窦性心律不齐（RSA）、教导和脱离互动是否与母亲和其3岁孩子（N = 47）之间更强或更弱的RSA共同调节有关，使用多级耦合自回归模型对观察到的18分钟二元互动进行建模。随着时间的推移，母亲更多的教导与母婴RSA更强的共同调节相关，而母亲的脱离互动则与较弱的共同调节相关，具体而言，在母亲脱离互动程度较高时，亲子RSA差异更大。当母亲的基线RSA较高时，母婴RSA的共同调节也较弱。研究结果有助于丰富关于幼儿期亲子生理共同调节实时模式的新兴知识库，并表明母亲的生理状况和与孩子的行为互动在母婴生理共同调节模式中起着重要作用。
