Data were drawn from an ongoing study of preschoolers (N = 221). Mothers self‐reported experiences of intimate partner violence (IPV) and parenting practices, and collected three saliva samples (waking, midday, and bedtime) on themselves and their child on 2 consecutive days. Saliva samples were later assayed for cortisol. Bootstrapped mediation analyses revealed IPV to indirectly impact child diurnal cortisol through positive parenting. Specifically, greater exposure to IPV was associated with reduced positive parenting and subsequently heightened child waking cortisol levels. IPV did not indirectly impact child diurnal cortisol via autonomy supporting parenting or maternal diurnal cortisol. These findings suggest a possible pathway by which mother's experience of IPV indirectly influences child physiological regulation via maternal positive parenting.

亲密伴侣暴力通过积极的养育方式间接失调儿童昼夜肾上腺皮质功能

数据来自一项正在进行的学龄前儿童研究（N = 221）。母亲自我报告亲密伴侣暴力 (IPV) 和养育方式的经历，并连续 2 天收集了自己和孩子的三个唾液样本（清醒、中午和就寝时间）。后来对唾液样本进行了皮质醇分析。Bootstrapped 中介分析显示 IPV 通过积极养育间接影响儿童昼夜皮质醇。具体而言，更多地暴露于 IPV 与积极养育的减少以及随后儿童清醒时皮质醇水平升高有关。IPV 不会通过支持养育的自主权或母亲的昼夜皮质醇间接影响儿童昼夜皮质醇。这些发现提出了一种可能的途径，通过该途径，母亲
