Nurses play an important role in medical and health services and insomnia symptoms were relatively high among nurses, especially during the epidemic of 2019 coronavirus disease. Insomnia not only damages the physical and mental health of the individual, but also reduces the efficiency of their work and the quality of care, ultimately impacting on patient care.
The purpose of this study was to explore the role of perceived organizational support and psychological capital in the relationship between occupational stress and insomnia among Chinese nurses.
A cross-sectional study has been carried out in a tertiary grade A hospital in Shandong Province, China from March 2021 to May 2021. The self-administered questionnaires were distributed to 810 nurses, which including Chinese Effort-Reward Imbalance Scale, Athens Insomnia Scale, Perceived Organizational Support Questionnaire, Chinese Psychological Capital Questionnaire, gender, age, education level and other demographic characteristics. Effective respondents were 658 (81.2%). Descriptive analysis, independent-samples -test, one-way analysis of variance, Pearson correlation analyses, ordinary least-squares regression and the bootstrap method were used for data analysis.
The prevalence of insomnia symptoms in this study was found to be 57.3%. There were significant differences in insomnia symptoms in weekly working hours ( = -2.027, = 0.043), with chronic disease ( = -2.825, = 0.005), negative life events ( = -5.340, < 0.001), departments ( = 3.077, = 0.006) and position ( = 2.322, = 0.021) among nurses. Overall, the serial-multiple mediations of perceived organizational support and psychological capital in the relationship between occupational stress and insomnia were found to be statistically significant.
The prevalence of insomnia symptoms was comparatively high among Chinese nurses, and occupational stress had direct negative influence on it. Perceived organizational support and psychological capital acted as chained mediating factor could partially relieve insomnia symptoms related to occupational stress. Supportive working environment should be provided, and improving psychological capital levels to help nurses coping with insomnia symptoms.
护士在医疗卫生服务中发挥着重要作用，护士群体中失眠症状的发生率相对较高，尤其是在2019冠状病毒病疫情期间。失眠不仅损害个人身心健康，还会降低工作效率和护理质量，最终影响患者护理。
本研究旨在探讨感知组织支持和心理资本在中国护士职业压力与失眠关系中的作用。
2021年3月至2021年5月在中国山东省一家三级甲等医院开展了一项横断面研究。向810名护士发放了自填式问卷，包括中文版努力-回报失衡量表、雅典失眠量表、感知组织支持问卷、中文版心理资本问卷、性别、年龄、教育程度等人口学特征。有效应答者为658人（81.2%）。采用描述性分析、独立样本t检验、单因素方差分析、Pearson相关分析、普通最小二乘回归和Bootstrap法进行数据分析。
本研究中失眠症状的发生率为57.3%。护士在每周工作时长（t = -2.027，P = 0.043）、患有慢性病（t = -2.825，P = 0.005）、经历负性生活事件（t = -5.340，P < 0.001）、科室（F = 3.077，P = 0.006）和职位（t = 2.322，P = 0.021）方面的失眠症状存在显著差异。总体而言，感知组织支持和心理资本在职业压力与失眠关系中的链式多重中介作用具有统计学意义。
中国护士中失眠症状的发生率较高，职业压力对其有直接负面影响。感知组织支持和心理资本作为链式中介因素可部分缓解与职业压力相关的失眠症状。应提供支持性的工作环境，并提高心理资本水平以帮助护士应对失眠症状。
