Aim

We aimed to examine the cross-sectional and longitudinal associations between sleep and work-related impaired cognitive and emotional functioning in police employees.

Methods

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.

Results

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.

Conclusion

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.

警察雇员睡眠与工作相关认知和情绪功能之间的关联

目的

我们的目的是研究警察雇员睡眠与工作相关的认知和情绪功能受损之间的横向和纵向关联。

方法

这项研究包括基线时在挪威警察区工作的 410 名参与者（52% 为男性），其中 50% 的人在 6 个月后的随访中也参与了该研究。调查问卷包括衡量工作安排、睡眠时间、失眠以及工作中认知和情绪功能受损的项目。

结果

结果表明，失眠与基线时测量的工作相关情绪功能受损以及基线和随访时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。

结论

我们的研究表明，失眠与工作情绪功能之间的关系可能是短暂的，而失眠可能与当前和未来的认知功能受损有关。建议在更大的样本中重复研究结果。研究结果呼吁重视警察雇员睡眠问题的预防和治疗，将其作为维持和改善工作中认知和情绪功能的一种手段，从而降低表现受损以及负面健康和安全后果的风险。
