Respiratory sinus arrhythmia (RSA; a measure of respiratory modulation of vagal control of heart rate) is a dynamic process. For mothers, RSA functioning has been associated with depressive symptoms and coincides with supportive parenting. However, research has largely focused on RSA suppression (i.e., difference score from rest to stress task). The present study examined depressive symptoms and supportive parenting with RSA instability-a dynamic measure of the magnitude of RSA change across a task. In two samples of mothers (N = 210), one with preschoolers (Study 1: n = 108, M = 30.68 years, SD = 6.06, 47.0% Black, 43.0% White) and one with adolescents (Study 2: n = 102, M = 35.51, SD = 6.51, 75.2% Black), RSA instability was calculated during an interaction task. In both studies, instrumental supportive parenting behaviors were negatively related to RSA instability. Findings provide preliminary support for RSA instability as an indicator of physiological dysregulation for mothers.
呼吸窦性心律失常（RSA；一种衡量迷走神经对心率呼吸调节的指标）是一个动态过程。对于母亲来说，RSA 功能与抑郁症状有关，并与支持性育儿方式相吻合。然而，研究主要集中在 RSA 抑制（即，从休息到应激任务的差值）上。本研究考察了抑郁症状和支持性育儿与 RSA 不稳定性的关系——这是一种衡量任务过程中 RSA 变化幅度的动态指标。在两个母亲样本（N=210）中，一个是学龄前儿童（研究 1：n=108，M=30.68 岁，SD=6.06，47.0%为黑人，43.0%为白人），另一个是青少年（研究 2：n=102，M=35.51，SD=6.51，75.2%为黑人），在互动任务中计算了 RSA 不稳定性。在两项研究中，工具性支持性育儿行为与 RSA 不稳定性呈负相关。这些发现初步支持了 RSA 不稳定性作为母亲生理失调的指标。
