Abstract
Objective: The aim of the study was to evaluate the effectiveness of interventions to improve sleep, reduce fatigue, and advance the well-being of team truck drivers.
Methods: In a randomized controlled trial ( k = 24 teams; N = 49 drivers; 61.3% of planned sample), intervention teams were exposed to baseline (3-4 weeks), cab enhancements (active suspension seat, therapeutic mattress; 3-4 weeks), and cab enhancements plus a behavioral sleep-health program (1-2 months). Control teams worked as usual during the same period.
Results: Trends in sleep-related outcomes favored the intervention. Large and statistically significant intervention effects were observed for objectively measured physical activity (a behavioral program target). The discussion of results addresses effect sizes, statistical power, intervention exposure, and work organization.
Conclusions: Trends, effect sizes, and significant findings in this rare trial provide valuable guidance for future efforts to improve working conditions and outcomes for team drivers.
