Abstract:
Objective To explore the role of mindfullness in the negative life events,depression,and poor sleep quality.Methods Using five facet mindfullness questionnaire(FFMQ),adolescents self-rating life events checklist (ASLEC),self-rating depression scale (SDS) and Pittsburgh sleep quality index (PSQI) to investigate 2 792 freshmen in a medical university in Guangzhou.Results The FFMQ score (126.02±12.14) was negatively correlated with ASLEC score(23.93±19.81),SDS score(35.89±7.31) and PSQI score (3.45±2.13) (r=-0.17,r=-0.44,r=-0.26,P＜0.01).The boys in the aspects of " mindfullnessinaction" scored significantly higher than that of girls (21.20 ± 3.36,20.52±2.88,P＜0.01).The girls scored significantly higher than boys in the PSQI,SDS (3.58±2.15,3.21 ±2.08,P＜0.05;36.22±7.26,35.27±7.35,P＜0.01).Mindfullness and sleep quality showed a chain-mediated effect between negative life events and depression,and the model fitting was good (RMSEA =0.048,CFI =0.962,TLI =0.943).The total mediating effect size was 61.41％.The mediating path through mindfullness,with the effect size of 16.71％,and the chain-mediating effect was 8.94％.Conclusion The higher the level of mindfullness,the lower the individual's depression score and the better the quality of sleep.Mindfullness and the sleep quality play a role of chain-mediating effect between negative life events and depression.
