Psychosocial job stressor studies usually examine one exposure at a time and focus on individual workers. In this study we examined the accumulation of work stressors in work units and its association with psychological distress (PD) on work-unit level. We also investigated whether high workplace social capital modifies the effect.
We examined survey responses from 813 Finnish health and social services (HSS) work units, comprising 9 502 employees, in a cross-sectional study design. The survey was conducted in 2021. We calculated odds ratios for the association between accumulating job stressors and PD. We also analyzed the interaction between work stressors and the effect modification of high workplace social capital.
We found that HSS work units with high percentage of employees having high job demands and low rewards (OR 7.2, 95% CI 3.7, 13.8) have an increased risk of higher PD in the work unit. We also found indication of high social capital possibly modifying the effect of job stressors on PD. The results suggest that accumulated job stressors are associated with PD on work unit level, with excess risk for PD compared to the stressors acting separately.
The results indicate that the effect of accumulating job stressors should be further studied on work-unit level. Participatory organizational-level and work-unit level interventions to tackle job stressors and to improve workplace social capital are warranted.
心理社会工作压力源研究通常一次只研究一种暴露，并侧重于个体工人。在这项研究中，我们研究了工作单位中工作压力源的积累及其与工作单位层面心理困扰（PD）的关系。我们还调查了高工作场所社会资本是否会改变这种影响。
我们在一项横断面研究设计中检查了来自 813 个芬兰卫生和社会服务（HSS）工作单位的 9502 名员工的调查回复。该调查于 2021 年进行。我们计算了累积工作压力源与 PD 之间关联的优势比。我们还分析了工作压力源与高工作场所社会资本的效应修饰之间的相互作用。
我们发现，具有高工作需求和低回报员工比例高的 HSS 工作单位（OR7.2，95%CI3.7，13.8），其工作单位中 PD 风险增加。我们还发现，高社会资本可能修饰了工作压力源对 PD 的影响。结果表明，累积工作压力源与工作单位层面的 PD 相关，与单独作用的压力源相比，PD 的风险更高。
结果表明，应进一步在工作单位层面研究累积工作压力源的影响。有必要采取参与性组织层面和工作单位层面的干预措施，以解决工作压力源问题并提高工作场所社会资本。
