Intervention study for stress reduction by workplace environment based on occupational stress models

本研究考察了健康工作组织干预对员工心理健康和工作绩效的影响。一家市中心、一家急救医院和一家电气制造公司是研究对象。在各自的研究引用中，12个医院病房和14条电子设备生产线被随机分配到干预组和控制组。我们的干预措施包括在组织中建立和促进员工解决问题的团队。干预过程旨在改善工作环境，以促进减轻压力。根据在员工中进行的压力调查，团队负责制定和实施针对其特定地点的需求的行动计划。假设如果干预过程强调信息交换、员工参与和社交网络，以及员工赋权，这些活动将对印度人的心理健康…产生良好的影响在近一年的干预期间，环境得到了很大的改善。在内城急诊医院的研究中，7个干预病房的护士流失速度低于对照病房，但差异无统计学意义。对于制造业工人而言，轻微的精神流动性和自我报告的工作绩效在统计学上有显著的干预效果。研究结果表明，以理论为导向的参与式工作场所改善干预措施有助于减轻压力，对员工的心理健康和行为有积极影响。然而，结果并不是决定性的。研究考虑了几个方法学上的局限性：观察期较短、结果指标的选择、包括单位选择在内的随机化方法和样本流失似乎是至关重要的。但是，访谈和定性问卷的过程评估表明，干预的可行性和对活动的总体主观评价是好的。进程评价还揭示了开展参与性干预的几个障碍。克服这些障碍和方法缺陷将产生更清晰的结果。较少

This study examined the effectiveness of healthy work organization interventions on worker mental health and performance. An inner city, acute-care hospital and an electric manufacturing company were the subject study populations. Twelve hospital wards and fourteen lines manufacturing an electronic device were randomly allocated into intervention and control groups, at the respective study cites. Our intervention involved establishing and facilitating employee problem-solving teams in the organizations. The intervention process was directed at improving the work environment to facilitate stress reduction. Based on a stress survey conducted among the employees, teams were charged with developing and implementing action plans tailored to the needs of their specific site. It was hypothesized that if an intervention process emphasized information exchange, employee participation and social networking, and employee empowerment, such activities would have a good affect on mental health indic … More es and/or behaviors of the participants.Many environmental improvements were achieved during the almost one-year intervention period. In the study of the inner city, acute-care hospital, the turnover of nurses was less rapid among the seven intervention wards compared to the control ones, but the difference was not statistically significant. As for the manufacturing workers, there were statistically significant intervention effects on minor psychiatric mobility and self-reported job performance.The findings suggest that theory-oriented participatory intervention for workplace improvements to facilitate stress reduction has beneficial effects on employees' mental health and behaviors. However, the results were not conclusive. Several methodological limitations are considered : the rather short observation period, selection of outcome measures, ways of randomization including the selection of the units, and sample attrition appeared to be crucial.However, process evaluation from interviews and qualitative questionnaires showed the feasibility of intervention and overall subjective evaluation of the activities were good. Process evaluation also revealed several obstacles against conducting participatory intervention. Overcoming these obstacles and methodological flaws would produce clearer findings. Less
