This research examined the moderating effect of the autonomic nervous system (ANS) on the associations between relational victimization and reactive and proactive relational aggression. Both branches of the ANS, the parasympathetic nervous system (indexed by respiratory sinus arrhythmia reactivity; RSA-Reactivity) and the sympathetic nervous system (indexed by skin conductance level reactivity; SCL-Reactivity), were examined. Emerging adults (N = 168) self-reported on relational victimization and proactive and reactive relational aggression; RSA-Reactivity and SCL-Reactivity were assessed in response to a laboratory stressor. Relational victimization predicted heightened reactive relational aggression given RSA augmentation/high SCL-Reactivity (i.e., coactivation) and RSA withdrawal/low SCL-Reactivity (i.e., coinhibition). In addition, relational victimization predicted heightened reactive relational aggression given RSA augmentation/low SCL-Reactivity (i.e., reciprocal parasympathetic activation). This study extends previous research on relational victimization and provides novel evidence that (a) exposure to relational victimization is associated with reactive relational aggression, but not proactive relational aggression, and (b) parasympathetic and sympathetic nervous system reactivity jointly moderate the link between relational victimization and reactive relational aggression.
本研究考察了自主神经系统（ANS）对关系型受害经历与反应性和主动性关系攻击之间关联的调节作用。研究考察了ANS的两个分支，即副交感神经系统（以呼吸性窦性心律不齐反应性为指标；RSA-反应性）和交感神经系统（以皮肤电导率水平反应性为指标；SCL-反应性）。新兴成年人（N = 168）自我报告了关系型受害经历以及主动性和反应性关系攻击；在应对实验室应激源时评估了RSA-反应性和SCL-反应性。在RSA增强/高SCL-反应性（即共同激活）以及RSA减退/低SCL-反应性（即共同抑制）的情况下，关系型受害经历预示着反应性关系攻击的增强。此外，在RSA增强/低SCL-反应性（即副交感神经反向激活）的情况下，关系型受害经历预示着反应性关系攻击的增强。本研究扩展了先前关于关系型受害经历的研究，并提供了新的证据，即（a）经历关系型受害经历与反应性关系攻击有关，但与主动性关系攻击无关；（b）副交感神经系统和交感神经系统反应性共同调节关系型受害经历与反应性关系攻击之间的联系。
