Linking insomnia to workplace injuries: A moderated mediation model of supervisor safety priority and safety behavior.
基于自我调节资源理论，研究失眠如何通过降低安全行为导致工伤，并发现主管安全优先性可减弱这一负面效应，为睡眠干预减少工伤提供依据。
This study investigated why and how insomnia can relate to workplace injuries, which continue to have high human and economic costs. Utilizing the self-regulatory resource theory, we argue that insomnia decreases workers' safety behaviors, resulting in increased workplace injuries. Moreover, in order to ultimately derive organizational interventions to alleviate the detrimental impact of insomnia on workplace injuries, we propose that supervisor safety priority can create situational strength that can prevent workers from behaving unsafely despite experiencing insomnia. Our theoretical model was examined and empirically supported using hierarchically nested data collected from supervisors (N = 482) and workers (N = 2,737) in a midsized construction services company. Results were consistent with the proposed conceptual framework; the relationship between insomnia and injuries is explained by the influence of insomnia on safety behaviors. For workers supervised by supervisors with high safety priority, both the relationship between insomnia and safety behaviors and the indirect relationship between insomnia and workplace injuries were weaker. We provide theoretical implications for future safety research and suggest tentative directions for practitioners working to reduce workplace injuries through sleep-oriented interventions.
