Mindfulness improve the quality of sleep of the medical staff: the mediating role of resilience

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 CD-RISC 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. Key words: Mindfulness; Resilience; Sleep quality; Mediating effects
