睡眠时间参数对学前儿童问题行为的影响:消极情绪性的调节作用

本研究以338名学前儿童为被试，采用母亲报告法探究了学前儿童睡眠时间与问题行为之间的关系，以及儿童消极情绪性的调节作用。结果发现：（1）睡眠总时长对儿童内化和外化问题行为的主效应显著，而睡眠总时长与消极情绪性对儿童内化和外化问题行为的交互作用不显著；（2）夜间睡眠比对儿童内化问题行为的主效应显著，对儿童外化问题行为的主效应不显著；夜间睡眠比与消极情绪性对儿童内化问题行为的交互作用显著，即对高消极情绪性的儿童，夜间睡眠比能够显著负向预测其内化问题行为，而对低消极情绪性的儿童，夜间睡眠比对其内化问题行为的预测并不显著；夜间睡眠比与消极情绪性对儿童外化问题行为的交互作用不显著。

Sleep Time Parameters and Preschoolers' Problem Behaviors: The Moderating Role of Negative Emotionality

The present study examined the joint effects of sleep time parameters and negative emotionality on preschoolers' problem behaviors among 338 preschoolers. Data were collected from mothers' reports. Results indicated that:(1) the main effects of total sleep duration on preschoolers' internalizing and externalizing problems were significant, but the moderations of negative emotionality on the relationships between total sleep duration and problem behaviors were not significant; (2) the main effect of the proportion of nighttime sleep to total sleep was significant on internalizing problems but not externalizing problems; the moderation of negative emotionality on the relationship between the proportion of nighttime sleep to total sleep and internalizing problem behavior was significant. The further analysis indicated that the proportion of nighttime sleep to total sleep was negatively associated with internalizing problem behavior in preschoolers with high negative emotionality but not low negative emotionality; the moderation of negative emotionality on the relationship between the proportion of nighttime sleep to total sleep and externalizing problem behaviors was not significant.
