Linking Challenge–Hindrance Stressors to Safety Outcomes and Performance: A Dual Mediation Model for Construction Workers

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.
