ABSTRACT

We conducted 3 studies to investigate how poor quality sleep relates to work injuries. First, using a sample of employed people living in the United Kingdom (N = 4,238; Study 1), we found that poor quality sleep was related to more frequent workplace injuries via negative affect rather than cognitive failures. Second, we again compared parallel pathways using a sample of USA employees (N = 202; Study 2): poor quality sleep was related to more frequent work injuries via work-related negative affect but not work-related cognitive failures. Third, we used a 2-wave sample of employees from the United Kingdom (N = 71; Study 3) finding that poor quality sleep was related to more frequent work injuries 7 weeks later via negative affect. Comparing high arousal and low arousal negative affect as competing pathways showed that there was a significant indirect effect of the former on the poor quality sleep-work injuries relationship but not the latter. Across 3 studies, we implicated the role of self-control failure stemming from poor quality sleep in predicting more frequent work injuries and suggested initiatives targeting high arousal negative affect as a way of reducing work injuries.

摘要

我们进行了3项研究，以调查睡眠质量差与工伤之间的关系。首先，通过使用居住在英国的就业人口的样本（N  = 4,238；研究1），我们发现睡眠质量差与负面影响而不是认知障碍与工作场所更频繁的伤害有关。其次，我们再次使用美国雇员的样本（N  = 202；研究2）比较了平行途径：低质量的睡眠与工作相关的负面影响与更频繁的工作伤害有关，而与工作相关的认知障碍无关。第三，我们使用了来自英国（N = 71; 研究3）发现不良的睡眠与7周后因负面影响而导致的更频繁的工伤有关。比较高唤醒和低唤醒的负面影响作为竞争路径，表明前者对质量较差的睡眠—工伤关系具有显着的间接影响，而对后者则没有。在3项研究中，我们暗示了由于睡眠质量差引起的自我控制失败在预测更频繁的工伤中的作用，并提出了针对高唤醒负面影响的措施，以减少工伤。
