副交感神经过程似乎是虐待家庭中不适应的亲子互动的基础，但尚不清楚儿童虐待的严重程度和亚型是否会导致呼吸性窦性心律失常(RSA)的亲子共同调节不同。采用动态时间序列模型分析了虐待和非虐待母子二元(N=146，年龄3-5岁)在两个二元任务中的RSA协同调节。非虐待对偶表现出阳性的RSA一致性，但虐待对偶(当作为一个组检查时)不显示。然而，当按亚型单独检查时，在二元RSA中，身体虐待的二元组显示正一致性，而忽略的二元组不一致性。虐待的严重性进一步修正了模式，这预示着两组中不一致的RSA(一方的RSA预测另一方的RSA下降)。具体地说，身体虐待严重程度越高，休息的孩子RSA越低，母亲RSA随着时间的推移而下降，母亲RSA预测孩子RSA随着时间的推移而下降，这表明母亲驱动的二元应激反应。更高的忽视严重程度预示着儿童RSA随着时间的推移而增加，而儿童RSA预测母亲RSA随着时间的推移而下降，这表明儿童驱动的母亲压力反应。这些发现表明，在非虐待、身体虐待和疏忽的母子二元组中存在不同的RSA协同调节模式，这可能为虐待家庭中压力调节的病因学和干预提供信息。
Parasympathetic processes appear to underlie maladaptive parent-child interactions in maltreating families, but it is unknown whether parent-child coregulation of respiratory sinus arrhythmia (RSA) differs by child maltreatment severity and subtype. RSA coregulation in maltreating and non-maltreating mother-child dyads (N=146; Age 3-5 years) during two dyadic tasks was analyzed using dynamic time series modeling. Non-maltreating dyads showed positive RSA concordance but maltreating dyads (when examined as one group) did not. However, when examined separately by subtype, physically abusive dyads showed positive concordance, and neglectful dyads no concordance, in dyadic RSA. Patterns were further modified by maltreatment severity, which predicted discordant RSA (one partner’s RSA predicting decreases in the other’s) in both groups. Specifically, higher physical abuse severity predicted lower resting child RSA, declining mother RSA over time, and mother RSA predicting declines in child RSA over time, suggesting a mother-driven dyadic stress response. Higher neglect severity predicted increasing child RSA over time and child RSA predicting declines in mother RSA over time, suggesting a child-driven maternal stress response. These findings show there are distinct patterns of RSA coregulation in non-maltreating, physically abusive, and neglectful mother-child dyads, which may inform etiology and intervention with respect to stress regulation in maltreating families.
