To determine job stress among Chinese operating room nurses, test the mediating effect of burnout and verify the moderating effect of over-commitment between job stress and mental health.
A descriptive, cross-sectional study.
A multistage sampling method was adopted. First, a random sampling method was used to select 30 tertiary hospitals in Beijing, after which 509 operating room nurses were selected by convenience sampling from March-June 2017. Self-administered questionnaires were used to evaluate job stress, burnout, and organizational commitment among participants. Multiple-group path analysis was used to test the mediating effect and the moderating effect.
Of all nurses, 70.3% were in a state of job stress, which had negative effects on organizational commitment mediated by emotional exhaustion and depersonalization. The result of multiple-group path analysis showed that the path coefficients are different between the low and high groups of over-commitment. When facing job stress, operating room nurses with low over-commitment were more likely to have emotional exhaustion (β = 0.750 vs. 0.602), while those with high over-commitment were more likely to have low organizational commitment (β = -0.641 vs. -0.594).
The job stress of operating room nurses in China was high. Burnout played a mediating role between job stress and organizational commitment. Over-commitment played a moderating role in the relationship among job stress, burnout, and organizational commitment.
This study analysed the relationship among operating room nurses' job stress, burnout, and organizational commitment. The findings provided confirmatory support on the mediated effect of burnout between job stress and organizational commitment and the moderation effect of over-commitment. Different measures are needed to reduce job stress, as for easing burnout and improving organizational commitment among different groups of nurses.
了解中国手术室护士的工作压力，检验倦怠的中介作用，并验证过度投入在工作压力与心理健康之间的调节作用。
描述性、横断面研究。
采用多阶段抽样方法。首先，采用随机抽样法在北京选取 30 家三级医院，然后于 2017 年 3 月至 6 月采用便利抽样法选取 509 名手术室护士。采用自填式问卷评估参与者的工作压力、倦怠和组织承诺。采用多组路径分析检验中介作用和调节作用。
在所有护士中，70.3%处于工作压力状态，这种状态通过情绪衰竭和去人性化对组织承诺产生负面影响。多组路径分析结果表明，过度投入的高低分组之间的路径系数不同。面对工作压力时，低过度投入的手术室护士更有可能出现情绪衰竭（β=0.750 比 0.602），而高过度投入的护士更有可能出现低组织承诺（β=-0.641 比-0.594）。
中国手术室护士的工作压力较高。倦怠在工作压力与组织承诺之间起中介作用。过度投入在工作压力、倦怠与组织承诺之间的关系中起调节作用。
本研究分析了手术室护士工作压力、倦怠与组织承诺之间的关系。研究结果为倦怠在工作压力与组织承诺之间的中介作用以及过度投入在工作压力、倦怠与组织承诺之间的调节作用提供了验证性支持。需要采取不同的措施来降低工作压力，以缓解不同组别护士的倦怠并提高组织承诺。
