The current study explored the role of parents' negative and positive affect in adolescent respiratory sinus arrhythmia (RSA) reactivity during a parent-adolescent conflict discussion task and the moderating effects of adolescent sex and age. Questionnaire data were collected from 206 adolescents (10-18 years of age; M = 13.37 years) and their primary caregivers (83.3% biological mothers). Electrocardiogram and respiration data were collected from adolescents, and RSA variables were computed. Parent affect was coded during the conflict discussion task. Multilevel modeling was used to distinguish the between- and within-individual effects of parent affect on adolescent RSA. Results indicated that observed within-parent-teen dyad anger was negatively associated with adolescent RSA, controlling for previous-minute RSA level, particularly among adolescents 13 years and older. In addition, observed between-dyad positive affect was positively linked to RSA for both boys and girls when previous-minute RSA level was controlled. Within-dyad positive affect was positively related to girl's RSA only. These findings suggest that expressions of positive affect may be related to better vagal regulation (RSA increases), whereas expressions of anger may be related to poor vagal regulation (RSA decreases) during social engagement.
本研究探讨了在亲子冲突讨论任务中父母的消极和积极情绪对青少年呼吸性窦性心律不齐（RSA）反应性的作用，以及青少年性别和年龄的调节作用。研究收集了206名青少年（10 - 18岁；平均年龄M = 13.37岁）及其主要照顾者（83.3%为亲生母亲）的问卷数据。从青少年身上收集了心电图和呼吸数据，并计算了RSA变量。在冲突讨论任务中对父母的情绪进行编码。采用多层次模型来区分父母情绪对青少年RSA的个体间和个体内效应。结果表明，在控制前一分钟的RSA水平后，观察到的亲子二元组内的愤怒与青少年的RSA呈负相关，尤其是在13岁及以上的青少年中。此外，在控制前一分钟的RSA水平后，观察到的二元组间的积极情绪与男孩和女孩的RSA均呈正相关。二元组内的积极情绪仅与女孩的RSA呈正相关。这些发现表明，在社交互动中，积极情绪的表达可能与更好的迷走神经调节（RSA增加）有关，而愤怒的表达可能与较差的迷走神经调节（RSA降低）有关。
