We aimed to examine the cross-sectional and longitudinal associations between sleep and work-related impaired cognitive and emotional functioning in police employees.
This study included 410 participants (52% men) employed in a police district in Norway at baseline, of which 50% also participated in the study at 6 months later follow-up. The questionnaires included items measuring work schedule, sleep length, insomnia, as well as impaired cognitive and emotional functioning at work.
The results showed that insomnia was related to impaired work-related emotional functioning measured at baseline, and to impaired cognitive functioning measured at both baseline and follow-up. Sleep length and rotating shift work were not associated with future decline in cognitive or emotional functioning.
Our study indicates that the relationship between insomnia and emotional functioning at work may be transient, whereas insomnia can be related to both immediate and future impaired cognitive functioning. Replication of the findings in larger samples is advised. The findings call for an emphasis on the prevention and treatment of sleep problems among police employees as a mean of maintaining and improving cognitive and emotional functioning at work, and thereby reducing the risk for impaired performance and negative health and safety outcomes.
我们旨在研究警察群体中睡眠与工作相关的认知和情绪功能受损之间的横断面及纵向关联。
本研究纳入了挪威一个警区410名基线期在职的参与者(52%为男性),其中50%在6个月后的随访期也参与了研究。问卷包含了测量工作时间表、睡眠时间、失眠情况以及工作中认知和情绪功能受损情况的项目。
结果显示,失眠与基线期测量的工作相关情绪功能受损有关,也与基线期及随访期测量的认知功能受损有关。睡眠时间和轮班工作与未来认知或情绪功能下降无关。
我们的研究表明,失眠与工作中情绪功能之间的关系可能是短暂的,而失眠可能与当下及未来的认知功能受损均有关。建议在更大样本中重复这些研究结果。这些发现呼吁重视警察群体睡眠问题的预防和治疗,以此作为维持和改善工作中认知和情绪功能的一种手段,从而降低工作表现受损以及负面健康和安全后果的风险。
