Parent-child synchrony of respiratory sinus arrhythmia (RSA) varies by risk, but novel approaches are needed to capture individual contributions to synchrony. Multilevel state-trait modeling was applied to examine how parental psychological distress and parent and child average RSA during challenge (reflecting individual regulatory capacities) shaped RSA synchrony in mother-child (n = 71) and father-child (n = 47) interactions. RSA synchrony was curvilinear such that greater in-the-moment RSA reactivity in one partner prompted greater reactivity in the other. Higher risk (lower average RSA; higher distress) predicted in-the-moment RSA withdrawal to partner RSA changes, whereas lower risk (higher average RSA; lower distress) predicted in-the-moment RSA augmentation. In some models, one's higher average RSA prompted the partner's greater reactivity and thus synchrony when parental distress was higher. However, the presence and direction of synchrony was not consistently adaptive nor maladaptive across models, suggesting its meaning relies on theory and the parent and risk factors in question.
亲子呼吸窦性心律失常 (RSA) 的同步性因风险而异，但需要新的方法来捕捉对同步性的个体贡献。多层次状态-特质模型被应用于研究父母的心理困扰以及挑战期间父母和孩子的平均 RSA（反映个体调节能力）如何塑造母子（n=71）和父子（n=47）互动中的 RSA 同步性。RSA 同步性呈曲线形，即一方的即时 RSA 反应性越大，另一方的反应性就越大。更高的风险（更低的平均 RSA；更高的困扰）预示着对伴侣 RSA 变化的即时 RSA 撤回，而较低的风险（更高的平均 RSA；更低的困扰）预示着即时 RSA 增强。在一些模型中，当父母的困扰程度较高时，一个人的较高平均 RSA 促使伴侣的反应性更大，从而产生同步性。然而，在不同的模型中，同步性的存在和方向并不总是适应或不适应，这表明其意义取决于理论以及所涉及的父母和风险因素。
