BACKGROUND: Poor sleep is a growing concern in naval settings. Previous research has demonstrated that both civilian and military naval work strains sleep quality as well as a negative relationship between sleep quality and crew work performance. Variables moderating this relationship, such as leadership are of interest. MATERIALS AND METHODS: The present paper investigates how sailors' daily variations in sleep quality influence self-rated naval work-performance and interacts with perceived daily transformational leadership during a 30-day naval training mission. RESULTS: Using multi-level analysis, we found significant positive main effects of sleep quality and transformational leadership on naval work performance. Transformational leadership moderated the sleep quality-work performance link. Individuals who experienced higher levels of leadership were less prone to reductions in performance after poor sleep. CONCLUSIONS: Overall, the results suggest that leadership can partly negate some of the reduction in performance that often accompanies poor sleep, and that leadership becomes more important as the crew becomes sleepier.
