ABSTRACT

Objective To explore the impact of mindfulness on sleep and the mediating role of resilience.Methods A total of 540 medical staff in a three first-class hospital were assessed by five facet mindfulness questionnaire (FFMQ),Pittsburgh sleep quality index(PSQI) and Connor-Davidson resilience scale(CD-RISC).Results The average PSQI scores of medical staff was (6.67±3.20),of which the total score was equal or above 8 accounting for 37.04％.The positive rate of each factor of PSQI (factor score ≥2) was 51.67％ for daytime function,37.22％ for sleeping time,and 24.07％ for subjective sleep quality.The total score of PSQI was (6.67±3.20),the score of FFMQ was (119.55±9.90),and the score of CDRISC was (59.50± 12.77).PSQI was negatively correlated with FFMQ and CD-RISC (r=-0.29,-0.24;both P＜0.01),and there was a significant positive correlation between FFMQ and CD-RISC (r=0.48,P＜0.01).The factors of FFMQ associated with CD-RISC were followed by the description of mindfulness,the action of awareness,the non-reaction and the observation of mindfulness.The multi-linear regression analysis showed that resilience played a part mediating role between mindfulness and sleep quality,with a mediating effect of 20.9％.Conclusion Mindfulness has a positive impact on the quality of sleep of medical staff through resilience.
