Exploration of the relationship between sleep quality and negative life events and coping styles in adolescents based on structural equation model

Abstract

ObjectiveTo explore the correlation of sleep quality with negative life events and coping styles in adolescents based on structural equation modeling， and to provide references for improving the adolescents' sleep quality.MethodsFrom December 2021 to May 2022， a total of 767 junior middle school students from three schools in Chongqing were enrolled， and assessed using Pittsburgh Sleep Quality Index （PSQI）， Adolescent Self-rating Life Events Checklist （ASLEC） and Simplified Coping Style Questionnaire （SCSQ）. Then the structural equation model was applied to discuss the correlation of sleep quality with negative life events and coping styles in adolescents.ResultsA total of 222 adolescents （28.94%） were found to have sleep disorders. PSQI score was positively correlated with ASLEC score and negative coping dimension score of SCSQ （r=0.612， 0.590， P<0.01）， and negatively correlated with positive coping dimension score of SCSQ （r=-0.435， P<0.01）. The structural equation model of the relationship between negative life events， coping styles and sleep quality denoted that negative life events exhibited both direct and indirect positive effects on sleep quality （β=0.448， 0.322， P<0.05）， positive coping style had direct negative effects on sleep quality （β=-0.368， P<0.05）， and negative coping style had direct positive effects on sleep quality （β=0.442， P<0.05）.ConclusionNegative life events and negative coping style cause adverse effects on adolescents' sleep quality， while positive coping style exerts positive effects on adolescents' sleep quality.
