Temperamental negative affect and insufficient sleep have been independently associated with behavior problems during early childhood. However, it is unknown whether these factors interact to contribute to behavioral difficulties in young children. The current study examined the interactions between temperamental negative affect and both sleep onset time and sleep midpoint, assessed by actigraphy, in predicting externalizing and internalizing behaviors in a sample of 117 children (34-69 months of age). Children with high temperamental negative affect and either later sleep onset time or later sleep midpoint were more likely to exhibit externalizing and internalizing behaviors. These results emphasize the association between temperamental negative affect and behavioral difficulties, particularly for children with insufficient sleep.
情绪消极和睡眠不足与儿童早期的行为问题独立相关。然而，目前尚不清楚这些因素是否相互作用，从而导致幼儿出现行为困难。本研究通过活动记录仪评估，考察了气质性负性情绪与睡眠起始时间和睡眠中点（midpoint）之间的相互作用，在 117 名儿童（34-69 个月）样本中预测了外化和内化行为。具有高气质性负性情绪且睡眠起始时间晚或睡眠中点晚的儿童更有可能表现出外化和内化行为。这些结果强调了气质性负性情绪与行为困难之间的关联，尤其是对于睡眠不足的儿童。
