Analysis of the relationshiop and mediating factors between sleep quality and emotional regulation difficulties in millde school students
Objective To explore the relationship of sleep quality and emotional regulation difficulties in middle school students,and to analyze its mediating role of daytime dysfunction,social rejection and self-control ability,so as to provide a scien-tific reference for improving middle school students'mental health.Methods From October to November,2023,the Pittsburgh Sleep Quality Index,Adolescent Social Rejection Questionnaire,Brief Self-control Scale and Difficulties in Emotion Regulation Scaleshort Form(DERS-16)were used to assess 806 students recruited from four middle schools in Bengbu City by a convenient cluster random sampling method.And model-6 of PROCESS and 5 000 Bootstraps were used to make a chain-mediating model anal-ysis.Results Daytime dysfunction was positively correlated with sleep quality(r=0.57),social rejection(r=0.19),self-control(r=0.29,P<0.01).Self-control was positively correlated with emotional regulation difficulties(r=0.54,P<0.01).Poor sleep quality showed a significant positive association with on daytime dysfunction,and daytime dysfunction further affected social rejection,self-control ability and emotional regulation difficulties(β=0.86,0.60,1.27,1.56,P<0.05).Meanwhile,daytime dysfunction,social rejection and self-control played a serial mediating role in the relationship between sleep quality and emotional regulation difficulties(Estimate=0.11,95%CI=0.04-0.20,P<0.05).Conclusion The study reveals the complex relationship between sleep quality and emotional regulation difficulties in middle school students and provides a new theoretical basis for adolescent sleep improvement and mental health interventions.
