本研究旨在调查不同的人格变量是否与轮班工作耐受性相关，以及这些潜在的关联是否受到不同类型的轮班工作的调节。样本由 1505 名护士组成，轮班工作为两班或三班。性格特征是通过早晨性、灵活性、懒惰和坚韧来衡量的。早晨反映了早上相对较早警觉和晚上相对较早困倦的倾向。灵活性是指在一天中的奇怪时间工作和睡眠的能力，而疲倦则是指减少睡眠时变得疲倦/困倦的倾向。坚韧与对生活压力事件的适应能力有关。本研究中的因变量包括失眠、嗜睡、抑郁和焦虑的测量。控制人口变量和工作量的分层回归分析显示，早起与失眠呈显着负相关。轮班早起类型的相互作用总体上对抑郁症状显着。早起与三班制工人的抑郁症状较低水平几乎显着相关，但与两班制工人的抑郁症状无关。灵活性与较高水平的抑郁症状相关。轮班类型交互的灵活性对失眠很重要，表明灵活性与三班制工人的失眠呈负相关，与两班制工人的失眠无关。倦怠与更高水平的困倦、抑郁和焦虑症状相关。耐寒性与所有四个因变量的较低水平相关。 (C) 2010 Elsevier Ltd 和人体工程学协会。版权所有。
This study aimed to investigate whether different personality variables were associated with shift work tolerance, and whether these potential associations were moderated by various types of shift work. The sample comprised 1505 nurses who worked either two or three rotating shifts. Personality traits were measured in terms of morningness, flexibility, languidity and hardiness. Morningness reflects the tendency to be alert relatively early in the morning and sleepy relatively early in the evening. Flexibility denotes the ability to both work and sleep at odd times of the day, while languidity concerns the tendency to become tired/sleepy when cutting down on sleep. Hardiness relates to resilience to stressful life events. The dependent variables in this study comprised of measures of insomnia, sleepiness, depression and anxiety. Hierarchical regression analyses, which controlled for demographic variables and work load, revealed that Morningness was significantly and negatively related to insomnia. The Morningness by Shift type interaction was overall significant for depressive symptoms. Morningness was near significantly associated with lower levels of depressive symptoms in three-shift workers, but unrelated to depressive symptoms in two-shift workers. Flexibility was associated with higher levels of depressive symptoms. Flexibility by Shift type interaction was significant for insomnia, indicating that flexibility was negatively associated with insomnia for three-shift workers and unrelated with insomnia for two-shift workers. Languidity was associated with higher levels of sleepiness, depressive and anxiety symptoms. Hardiness was associated with lower levels of all four dependent variables.
