Occupational stressors have long been recognized as an important risk factor for injury accidents. The mechanisms underlying the relationships among challenge stressors, hindrance stressors, safety outcomes (occupational injuries), emotional experiences (attentiveness), and job performance (task performance) were investigated from the perspectives of the challenge-hindrance stress model and the conservation of resources theory. This study collected multi-source data over two timepoints for 105 safety supervisors and 379 construction workers in China. Results revealed that both challenge and hindrance stressors were positively related to occupational injuries, but only challenge stressors were positively associated with attentiveness. In addition, occupational injuries mediated the relationship between both challenge and hindrance stressors and task performance, while attentiveness mediated only the relationship between challenge stressors and task performance. These findings contribute to our knowledge of stress management in the construction project context and provide recommendations for stress management for front-line workers at construction sites.
职业压力源一直被认为是伤害事故的一个重要风险因素。本研究从挑战-阻碍压力模型和资源保存理论的角度出发，探讨了挑战压力源、阻碍压力源、安全结果（职业伤害）、情绪体验（专注）和工作绩效（任务绩效）之间关系的潜在机制。本研究通过两个时间点收集了来自中国 105 名安全主管和 379 名建筑工人的多源数据。结果表明，挑战压力源和阻碍压力源均与职业伤害呈正相关，但只有挑战压力源与专注呈正相关。此外，职业伤害在挑战压力源和阻碍压力源与任务绩效之间的关系中起中介作用，而专注仅在挑战压力源与任务绩效之间的关系中起中介作用。这些发现有助于我们了解建筑工程项目背景下的压力管理，并为施工现场一线工人的压力管理提供建议。
