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。
Abstract
Objective To explore the relationships between psychological stress and sleep quality of clinical nurses and the mediating effect of mental resilience in order to promote the physical and mental health of clinical nurses.Methods A total of 806 clinical nurses form a hospital in Beijing were assessed with Chinese Perceived Stress scales (CPSS), Pittsburgh sleep quality index(PSQI) and Connor-Davidson Resilience Scale(CD-RISC).Results The average PSQI score was 6.47±2.73 among these clinical nurses and 56.95% of them reported poor sleep quality (PSQIscore＞7). Psychological stress was significantly positively correlated with sleep quality and each factor of sleep(P<0.05). Mental resilience was significantly negatively correlated with sleep quality(P<0.05).Resilience partially mediated between psychological stress and sleep quality of clinical nurses, with a mediating effect of 0.15 and accounting for 29.5% of the total effect.Conclusions Psychological stress and mental resilience have a great impact on the sleep quality of clinical nurses. Resilience is a partial mediator between psychological stress and sleep quality.
