Job stress is a probable mediator of the relationship between safety climate and accident occurrence. To demonstrate this, this study investigates the relationship between safety climate, job stress, and accident risk using a large number of surveys. The study will use structural equation modeling (SEM) to analyze the data collected from the surveys to examine the effect of safety climate on accident risk through job stress.
The study is a cross-sectional study that was conducted on 1,530 male workers of a petrochemical company. The subjects were asked to complete several questionnaires during rest periods, which included demographic information, the Nordic safety climate questionnaire (NOSACQ-50), and the generic job stress questionnaire (GJSQ). Additionally, data on the frequency and intensity of accidents among participants were gathered from the health unit of the company. Path analysis was conducted by structural equation modeling (SEM) in Analysis of Moment Structures (AMOS) software.
The results revealed that the latent variable of safety climate with an effect coefficient of - 0.112 did not have a direct effect on accident risk (P = 0.343). However, safety climate with an effect coefficient of - 0.633 had an indirect effect on accident risk through job stress (P < 0.001). The total score of job stress had a significant direct effect (0.649) on accident risk (P < 0.001). Among the dimensions of safety climate, the variables of management's safety priority, commitment, and competence (- 0.108) and workers' safety commitment (- 0.107) had the highest indirect effect coefficients on accident risk. Among the dimensions of job stress, the highest indirect effects belonged to the variables of conflict at work (0.636), physical environment (0.631), and workload and responsibility (0.631), respectively.
The results of the study revealed that job stress mediates the relationship between safety climate and accident risk. This finding suggests that organizations can potentially decrease accidents in industries by addressing and managing job stress in the workplace.
工作压力可能是安全氛围与事故发生之间关系的中介。为了证明这一点，本研究使用大量调查来研究安全氛围、工作压力和事故风险之间的关系。该研究将使用结构方程模型（SEM）来分析从调查中收集的数据，以检查安全氛围通过工作压力对事故风险的影响。
本研究是一项横断面研究，对一家石化公司的 1530 名男性工人进行了研究。在休息时间，要求研究对象完成几份问卷，包括人口统计学信息、北欧安全氛围问卷（NOSACQ-50）和通用工作压力问卷（GJSQ）。此外，还从公司的健康部门收集了参与者的事故频率和强度数据。结构方程模型（SEM）在分析结构方程（AMOS）软件中进行路径分析。
结果表明，安全氛围的潜在变量的影响系数为-0.112，对事故风险没有直接影响（P=0.343）。然而，安全氛围通过工作压力对事故风险的间接影响为-0.633（P<0.001）。工作压力的总分对事故风险有显著的直接影响（0.649）（P<0.001）。在安全氛围的维度中，管理的安全优先级、承诺和能力（-0.108）以及工人的安全承诺（-0.107）对事故风险的间接影响系数最高。在工作压力的维度中，最高的间接影响属于工作冲突（0.636）、物理环境（0.631）和工作量和责任（0.631）。
研究结果表明，工作压力在安全氛围和事故风险之间的关系中起中介作用。这一发现表明，组织可以通过解决和管理工作场所的工作压力，潜在地减少工业事故。
