The goal of this study was to examine respiratory sinus arrhythmia (RSA), an indicator of parasympathetic nervous system-linked cardiac activity, and skin conductance level (SCL), a sympathetic indicator, as moderators of the link between child maltreatment and adolescent aggression.
Participants were 234 maltreated (48.3% male) and 128 (57.8% male) comparison youth aged 9-16 years participating in wave 2 of a longitudinal study.
Regression analyses suggest that among boys, high RSA may be protective against the effects of maltreatment on aggressive behavior. Among girls, the moderating effect of RSA was further moderated by SCL reactivity such that low levels of both baseline RSA and SCL reactivity, or conversely high levels of both baseline RSA and SCL reactivity, exacerbated the link between maltreatment and aggression.
High RSA may protect against the effects of maltreatment on aggressive behavior, though this effect may be moderated by SCL reactivity among girls.
本研究旨在探讨呼吸窦性心律失常(RSA)作为副交感神经系统相关心脏活动的指标,以及皮肤电导率(SCL)作为交感神经指标,在儿童虐待与青少年攻击行为之间的关系中的调节作用。
参与者为 234 名受虐待(48.3%为男性)和 128 名(57.8%为男性)比较组青少年,年龄为 9-16 岁,参与一项纵向研究的第 2 波。
回归分析表明,在男孩中,高 RSA 可能对虐待对攻击行为的影响具有保护作用。在女孩中,RSA 的调节作用进一步受到 SCL 反应性的调节,即基线 RSA 和 SCL 反应性均低,或者相反,基线 RSA 和 SCL 反应性均高,都会加剧虐待与攻击之间的联系。
高 RSA 可能对虐待对攻击行为的影响具有保护作用,但这种作用可能受到女孩中 SCL 反应性的调节。
