This study aimed to explore a possible process explaining the relationship between workaholism and sleep disorders, including two mediators: work-family conflict and emotional exhaustion. Moreover, since a possible buffering role of work engagement was recently proposed against the detrimental effects of workaholism, the aim was to examine the moderating role of work engagement in the relationship between workaholism and several outcomes such as work-family conflict, emotional exhaustion, and sleep disorders. Two models were tested using conditional process analysis for testing direct and indirect effects on a sample of 395 employees: (1) a serial multiple mediation model, and (2) the same serial multiple mediation model including the moderating role of work engagement. Results showed a significant mediating effect of both work-family conflict and emotional exhaustion. Moreover, work engagement moderated the relationship between workaholism and work-family conflict and the relationship between workaholism and emotional exhaustion. This work contributes to the understanding of the process underlying the relationship between workaholism and sleep disorders and to the literature reporting the possible protective role of work engagement on the negative outcomes of workaholism. Practical implications are also discussed.
本研究旨在探讨一种可能的过程，解释工作狂和睡眠障碍之间的关系，包括两个中介变量：工作-家庭冲突和情绪衰竭。此外，由于最近提出了工作投入可能对工作狂的有害影响起到缓冲作用，因此本研究旨在检验工作投入在工作狂与工作-家庭冲突、情绪衰竭和睡眠障碍等几个结果之间关系中的调节作用。使用条件过程分析对 395 名员工的样本测试了两个模型：（1）序列多重中介模型，以及（2）包含工作投入调节作用的相同序列多重中介模型。结果显示，工作-家庭冲突和情绪衰竭都具有显著的中介效应。此外，工作投入调节了工作狂和工作-家庭冲突之间的关系，以及工作狂和情绪衰竭之间的关系。这项工作有助于理解工作狂和睡眠障碍之间关系的潜在过程，并为报告工作投入对工作狂的负面结果可能具有保护作用的文献做出贡献。还讨论了实际意义。
