This study examined whether perceived unfairness about work was linked to midlife workers' insomnia symptoms over time, and if the association was mediated by negative work-to-family spillover (NWFS). We used 3 waves of longitudinal data across 20 years from the Midlife in the United States Study (N = 971, M = 40.52). Results revealed that, wave-to-wave increases in perceived unfairness about work predicted wave-to-wave increases in NWFS over 20 years. Wave-to-wave increases in NWFS, in turn, predicted wave-to-wave increases in insomnia symptoms. Perceived unfairness about work was indirectly, but not directly associated with insomnia symptoms through NWFS. These within-person indirect mediation pathways were found after controlling for sociodemographic and family characteristics, work hours, neuroticism, physical health, and between-person associations between perceived unfairness about work, NWFS, and insomnia symptoms. These findings suggest that perceived unfairness about work may degrade workers' sleep health over time, through the spillover of work stress to the personal domain.
这项研究考察了工作中感知到的不公平是否与中年工作者的失眠症状有关，以及这种关联是否受到负向工作-家庭溢出（NWFS）的影响。我们使用了来自美国中年研究（Midlife in the United States Study）的 3 个纵向数据波，跨度为 20 年（N=971，M=40.52）。结果表明，工作中感知到的不公平程度的逐波增加预示着 NWFS 在 20 年内的逐波增加。反过来，NWFS 的逐波增加预示着失眠症状的逐波增加。通过 NWFS，感知到的不公平与失眠症状之间存在间接关联，但不存在直接关联。这些个体内的间接中介途径是在控制了社会人口统计学和家庭特征、工作时间、神经质、身体健康以及工作中感知到的不公平、NWFS 和失眠症状之间的个体间关联之后发现的。这些发现表明，随着时间的推移，工作中的不公平感可能会通过工作压力向个人领域的溢出，损害工作者的睡眠健康。
