We tested the effects of a randomized controlled trial Total Worker Health intervention on workplace safety outcomes. The intervention targeted employee sleep at both the supervisor-level (e.g., sleep-specific support training) and employee-level (e.g., sleep tracking and individualized sleep feedback). The intervention components were developed using principles of the Total Worker Health approach and the theory of triadic influence for health behaviors. We hypothesized that employees in the treatment group would report greater safety compliance, safety participation, and safety motivation, and would be less likely to experience a work-related accident or injury following the intervention through improvements in sleep quantity and quality, as well as increased perceptions of supervisors' support for sleep. It was theorized that the indirect effects of the intervention on workplace safety outcomes via sleep mediators operated through a resource pathway, whereas the supervisor support for sleep mediator operated through an exchange pathway. Results broadly revealed that employees in the treatment group, compared to those in the control group, reported greater workplace safety behaviors and safety motivation, and reduced workplace accidents and injuries 9 months post-baseline, through lower dissatisfaction with sleep, reduced sleep-related impairments, and greater supervisor support for sleep 4 months post-baseline. Intervening on sleep and supervisor support for sleep in an integrated Total Worker Health framework can have a positive impact on workplace safety.

全面工人健康干预对工作场所安全的影响：睡眠和主管对睡眠的支持的中介作用。


我们测试了随机对照试验全面工人健康干预对工作场所安全结果的影响。干预措施针对主管级别（例如，针对睡眠的支持培训）和员工级别（例如，睡眠跟踪和个性化睡眠反馈）的员工睡眠。干预措施是根据工人全面健康方法的原则和健康行为的三元影响理论制定的。我们假设治疗组的员工会报告更高的安全合规性、安全参与度和安全动机，并且通过改善睡眠数量和质量以及增加干预后发生工伤事故或伤害的可能性较小。对主管对睡眠支持的看法。理论上，睡眠中介干预对工作场所安全结果的间接影响是通过资源途径运作的，而主管对睡眠中介的支持是通过交换途径运作的。结果总体显示，与对照组员工相比，治疗组员工表现出更好的工作场所安全行为和安全动机，并且通过降低对睡眠的不满程度、减少与睡眠相关的障碍，在基线后 9 个月减少了工作场所事故和伤害，以及监督者对基线后 4 个月睡眠的更大支持。在综合工人健康框架中对睡眠进行干预以及主管对睡眠的支持可以对工作场所安全产生积极影响。 （PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
