医护人员心理弹性在正念与睡眠质量间的中介效应

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

目的探讨正念对医护人员睡眠的影响以及心理弹性在其中的中介效应。方法以某三甲医院540名医护人员为被试,采用正念五因素量表(five facet mindfulness questionnaire,FFMQ)、心理弹性量表(Connor-Davidson resilienc escale,CD-RISC)、匹斯堡睡眠质量指数问卷(Pittsburgh sleep quality index,PSQI)进行测评。结果医护人员PSQI总得分为(6.67±3.20)分,其中总分≥8者占总人数37.04%;PSQI各因子阳性率(因子得分≥2)依次为日间功能51.67%、入睡时间37.22%、主观睡眠质量24.07%等。PSQI的总得分为(6.67±3.20)分、FFMQ的得分为(119.55±9.90)分、CD-RISC的得分为(59.50±12.77)分,PSQI与FFMQ、CD-RISC均呈显著负相关(r=-0.29,-0.24;均P<0.01),FFMQ与CD-RISC呈显著正相关(r=0.48,P<0.01),与心理弹性呈显著相关的正念各因子依次为正念描述、觉知地行动、不反应、正念观察。多层线性回归分析表明心理弹性在正念水平与睡眠质量之间起部分中介作用,中介效应为20.9%。结论正念水平通过心理弹性对医护人员的睡眠质量产生积极影响。

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.
