Abstract:
Shift work tolerance (SWT) refers to the ability to adapt to shift work without significant adverse consequences. The present study aimed to examine the individual differences in SWT and their predictors and outcomes. Latent profile analyses were conducted using cross-sectional data collected form 448 Chinese male sailors who experienced a prolonged (>30 d) non-24-h rotating shift schedule at sea. Depression, anxiety, sleep disturbance, fatigue, domestic disruption, job satisfaction, work engagement, digestive and cardiovascular symptoms were included as indicators of SWT. The results showed that there existed 2 latent profiles of SWT named as High SWT group and Low SWT group. High SWT group was characterized by low levels on all negative bio-psycho-social outcomes but high levels of work engagement and job satisfaction, while Low SWT group exhibited completely opposite characteristics compared to High SWT group. The level of hardiness could predict profile membership that those with higher level of hardiness were more likely to belong to High SWT group. However, there were no significant differences observed in job performance between two groups. In conclusion, hardiness can serve as a predictor of personnel selection for shift work and hardiness-based intervention programs should be encouraged among the shift workers.
摘要:
轮班公差(SWT)是指适应轮班工作而不会产生重大不利后果的能力。本研究旨在研究SWT的个体差异及其预测因素和结果。使用从448名中国男性水手中收集的横截面数据进行潜在剖面分析,这些水手在海上经历了长时间(>30d)的非24小时轮班时间表。抑郁症,焦虑,睡眠障碍,疲劳,国内混乱,工作满意度,工作参与,纳入消化系统和心血管症状作为SWT指标.结果表明,SWT存在2种潜在特征,分别为高SWT组和低SWT组。高SWT组的特点是所有负面的生物心理社会结果水平较低,但工作投入和工作满意度较高,而低SWT组表现出与高SWT组完全相反的特征。硬度水平可以预测具有较高硬度水平的人更有可能属于高SWT组。然而,两组间的工作绩效无显著差异.总之,坚定性可以作为轮班工作人员选择的预测指标,应鼓励轮班工作人员进行基于坚定性的干预计划。
