N2 - 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.
