Considering the high prevalence of aggressive problems found in middle childhood and their negative impacts on children's overall adjustment, it is important to explore factors that may give rise to childhood aggression, as well as the underlying mechanisms involved within the family context. Applying a biopsychosocial approach, the aim of our study was to examine the relations between emotion-related parenting behavior (ERPB, e.g., parental psychological control and parental emotion dysregulation) and childhood aggression with a focus on the potential moderating effects of parent-child physiological synchrony on these relations. Eighty-nine parent-child dyads (total N = 178) participated in the study (child M age = 8.76 years, SD = 1.81 years, 49 boys). At T1, ERPB was observed and coded from dyadic interaction and parent-child physiological synchrony was assessed using interbeat interval (IBI) calculated from the participant's heart rate (HR) during an interaction task. Parents also reported their child's aggressive behavior at T1 and 9 months later (T2). The results showed that for children demonstrating stronger physiological synchrony with their parents, higher levels of parental psychological control and parental emotion dysregulation predicted their more aggressive behavior. Our findings suggest that for certain negative types of ERPB, parent-child physiological synchrony seems to be a risk factor for the development of children's aggressive behavior.

情绪相关育儿行为与儿童攻击性的纵向关联：亲子生理同步的调节作用

考虑到在童年中期发现的攻击性问题的高发率及其对儿童整体适应的负面影响，探索可能导致儿童攻击性的因素以及家庭环境中涉及的潜在机制非常重要。应用生物心理社会方法，我们研究的目的是检查与情绪相关的育儿行为（ERPB，例如，父母心理控制和父母情绪失调）与儿童攻击性之间的关系，重点是亲子生理的潜在调节作用这些关系的同步。89 名亲子二人组（总 N = 178）参与了研究（儿童 M 年龄 = 8.76 岁，SD = 1.81 岁，49 名男孩）。在 T1，从二元交互中观察和编码 ERPB，并使用交互任务期间从参与者的心率 (HR) 计算的心跳间隔 (IBI) 评估亲子生理同步性。父母还报告了他们孩子在 T1 和 9 个月后 (T2) 的攻击行为。结果表明，对于与父母表现出更强生理同步性的儿童，更高水平的父母心理控制和父母情绪失调预示着他们更具有攻击性行为。我们的研究结果表明，对于某些负面类型的 ERPB，亲子生理同步似乎是儿童攻击行为发展的危险因素。父母还报告了他们孩子在 T1 和 9 个月后 (T2) 的攻击行为。结果表明，对于与父母表现出更强生理同步性的儿童，更高水平的父母心理控制和父母情绪失调预示着他们更具有攻击性行为。我们的研究结果表明，对于某些负面类型的 ERPB，亲子生理同步似乎是儿童攻击行为发展的危险因素。父母还报告了他们孩子在 T1 和 9 个月后 (T2) 的攻击行为。结果表明，对于与父母表现出更强生理同步性的儿童，更高水平的父母心理控制和父母情绪失调预示着他们更具有攻击性行为。我们的研究结果表明，对于某些负面类型的 ERPB，亲子生理同步似乎是儿童攻击行为发展的危险因素。
