Sleep was examined as a process variable in relations between verbal and physical parent-child conflict and change in children's internalizing and externalizing symptoms over time. Participants were 282 children at T1 (M age = 9.44 years; 48% girls), 280 children at T2 (M age = 10.41 years), and 275 children at T3 (M age = 11.35 years). Children reported on parent-child conflict, sleep was assessed with actigraphy, and parents reported on children's internalizing and externalizing symptoms. Autoregressive effects for sleep and internalizing and externalizing symptoms were controlled to examine change over time. Supportive of intervening processes, physical parent-child conflict at T1 and increased change in internalizing and externalizing symptoms at T3 were indirectly related through their shared association with reduced sleep continuity (efficiency, long wake episodes) at T2. Findings build on a small but growing literature and highlight the importance of considering the role of sleep in relations between family conflict and child development.
睡眠被作为一个过程变量进行研究，以探讨亲子言语冲突和身体冲突与儿童内化和外化症状随时间变化之间的关系。研究参与者包括282名处于T1阶段的儿童（平均年龄 = 9.44岁；48%为女孩）、280名处于T2阶段的儿童（平均年龄 = 10.41岁）和275名处于T3阶段的儿童（平均年龄 = 11.35岁）。儿童报告亲子冲突情况，通过活动记录仪评估睡眠，父母报告儿童的内化和外化症状。控制了睡眠以及内化和外化症状的自回归效应，以研究随时间的变化。支持干预过程的是，T1阶段的亲子身体冲突与T3阶段内化和外化症状变化增加之间存在间接关联，这是通过它们与T2阶段睡眠连续性降低（效率、长时间清醒发作）的共同关联实现的。研究结果基于少量但不断增长的文献，并强调了考虑睡眠在家庭冲突与儿童发展关系中的作用的重要性。
