摘要：Objective: This study examined the relationships among sleep problems, executive function and social behavior during the preschool period. In addition, the mediating role of executive function between sleep problems and social behavior was investigated. Methods: A total of 304 preschool children participated in this study. The data were collected through maternal reports. Results: First, preschoolers’ sleep problems were found to be significantly related to overt aggression and prosocial behavior. Second, preschoolers with sleep problems displayed lower levels of executive function. Third, preschoolers’ executive function was significantly associated with social behavior. Lastly, preschoolers’ executive function fully mediated the relationship between sleep problems and overt aggression, and between sleep problems and prosocial behavior. That is, preschoolers’ sleep problems had effects on overt aggression and prosocial behavior, only through the effects on executive function. Conclusion: This study contributes to the sleep literature by examining the role of executive function and emphasizes the importance of forming a healthy sleep habit during the preschool period.
