Peterson SA, Wolkow AP, Lockley SW, et al. - In this cross-sectional study of police officers (n = 3,140), experts investigated relationships between shift work features and schedules on burnout in police and whether sleep duration and sleepiness were related to burnout. Police working a greater frequency of long shifts were more inclined to have emotional exhaustion compared with those not working long shifts. Night shifts were related to depersonalization vs those not working nights. In comparison with fixed schedules, irregular schedules were related to emotional exhaustion and depersonalization. In comparison with those sleeping longer, police sleeping < 6 hours were more inclined to have emotional exhaustion, and excessive sleepiness was related to emotional exhaustion. Thus, results implied that irregular schedules and extended night shifts, sleep disturbances and work hours were associated with greater burnout risk in the police.
