School bullying and sleep quality among middle school students:The mediating role of social anxiety and the moderating role of left-behind experiences
To examine the mediating role of social anxiety and the moderating role of left-behind experi-ence in the relationship between school bullying and sleep quality,a sample of 758 middle school students completed measures of school bullying questionnaire,social interaction anxiety scale and Pittsburgh sleep quality index.The results showed that:(1)Traditional bullying/Cyberbullying could positively predict sleep quality;(2)Social anxiety played a partially mediating role of the relationship between school bullying and sleep quality;(3)Left-behind experience moderated the mediating model of cyberbullying.Thus,so-cial anxiety played a mediating role of the relationship between traditional bullying/cyberbullying and sleep quality,but left-behind experience only played a moderating role of the relationship between cyberbullying and sleep quality.
