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.
轮班工作耐力（SWT）是指适应轮班工作而没有明显不良后果的能力。本研究旨在探讨 SWT 的个体差异及其预测因素和结果。使用横断面数据对 448 名在中国海上经历长时间（>30 天）非 24 小时轮班制的男性海员进行了潜在剖面分析。抑郁、焦虑、睡眠障碍、疲劳、家庭破坏、工作满意度、工作投入、消化和心血管症状被作为 SWT 的指标。结果表明，存在两种 SWT 的潜在特征，分别是高 SWT 组和低 SWT 组。高 SWT 组的所有负面生物心理社会结果水平较低，但工作投入和工作满意度水平较高，而低 SWT 组与高 SWT 组的特点完全相反。坚韧水平可以预测特征群体，坚韧水平较高的人更有可能属于高 SWT 组。然而，两组之间的工作绩效没有显著差异。总之，坚韧可以作为轮班工作人员选拔的预测因素，应该鼓励轮班工人进行基于坚韧的干预计划。
