Healthy employee sleep is important for occupational safety, but the mechanisms that explain the relationships among sleep and safety-related behaviors remain unknown. We draw from Crain, Brossoit, and Fisher's (in press) work, nonwork, and sleep (WNS) framework and Barnes' (2012) model of sleep and self-regulation in organizations to investigate the influence of construction workers' self-reported sleep quantity (i.e., duration) and quality (i.e., feeling well-rest upon awakening, ability to fall asleep and remain asleep) on workplace cognitive failures (i.e., lapses in attention, memory, and action at work) and subsequent workplace safety behaviors (i.e., safety compliance and safety participation) and reports of minor injuries. Construction workers from two public works agencies completed surveys at baseline, 6 months, and 12 months. Our results suggest that workers with more insomnia symptoms on average reported engaging in fewer required and voluntary safety behaviors and were at a greater risk for workplace injuries. These effects were mediated by workplace cognitive failures. In addition, workers with greater sleep insufficiency on average reported lower safety compliance, but this effect was not mediated by workplace cognitive failures. These results have implications for future workplace interventions, suggesting that organizations striving to improve safety should prioritize interventions that will reduce workers' insomnia symptoms and improve their ability to quickly fall asleep and stay asleep throughout the night.

睡眠对工作场所认知失败和安全的影响。

健康的员工睡眠对职业安全很重要，但解释睡眠与安全相关行为之间关系的机制仍然未知。我们借鉴 Crain、Brossoit 和 Fisher（出版中）的工作、非工作和睡眠 (WNS) 框架和 Barnes (2012) 的睡眠和组织自我调节模型来调查建筑工人自我报告睡眠的影响数量（即持续时间）和质量（即醒来时感觉良好的休息、入睡和保持睡眠的能力）对工作场所认知失败（即注意力、记忆力和工作行为的失误）和随后的工作场所安全行为（即安全合规性和安全参与）和轻伤报告。来自两个公共工程机构的建筑工人在基线、6 个月和 12 个月完成了调查。我们的研究结果表明，平均而言，失眠症状较多的工人报告说，他们参与的必要和自愿安全行为较少，并且工作场所受伤的风险更大。这些影响是由工作场所的认知失败介导的。此外，平均而言，睡眠不足的工人报告的安全合规性较低，但这种影响并非由工作场所的认知失败所介导。这些结果对未来的工作场所干预措施有影响，表明努力提高安全性的组织应优先采取干预措施，以减少工人的失眠症状并提高他们快速入睡和整晚保持睡眠的能力。（PsycINFO 数据库记录 (c) 2018 APA，保留所有权利）。
