心理弹性对护士心理压力与睡眠质量的中介作用

 目的 探讨护士心理压力与睡眠质量的关系及其中介作用,为促进护士身心健康提供干预依据。方法 采用知觉压力量表(chinese perceived stress scales,CPSS)、匹斯堡睡眠质量指数量表(pittsburgh sleep quality index,PSQI)、中文版心理弹性量表(connor-davidson resilience scale,CD-RISC)对806名临床护士进行问卷调查。结果 护士睡眠质量总均分为(6.47±2.73)分,56.95%的临床护士存在睡眠质量问题(PSQI总分＞7)。心理压力与睡眠质量及其各因子呈明显正相关(P<0.05),心理弹性与睡眠质量呈明显负相关(P<0.05)。心理弹性在心理压力与睡眠质量间起了部分中介作用,中介效应为0.15,占总效应的比例为29.5%。结论 心理压力与心理弹性是影响护士睡眠质量的重要因素,心理弹性部分中介了心理压力对睡眠质量的影响。
