The over usage and over dependency on digital devices, like smartphones, has been considered as a growing international epidemic. The increased dependency on gadgets, especially smartphones for personal and official uses, has also brought many detrimental effects on individual users. Hence it is vital to understand the negative effects of smartphone usage on human. Therefore, this study aims to investigate the effects of bedtime smartphone usage on work performances, interpersonal conflicts, and work engagement, the mediating role of sleep quality among employees. Using a cross-sectional study design, a questionnaire-based field survey was conducted on 315 employees who participated as respondents. The results confirmed the negative effects of bedtime smartphone usage on sleep quality. Along with it, the effects of sleep quality on work performances, work engagements and interpersonal conflicts were also proven to be statistically significant. Regarding the mediating role of sleep quality, it was empirically evident that sleep quality mediates the relationship between bedtime smartphone usage with work performances and interpersonal conflicts. The findings revealed that bedtime smartphone usage reduces sleep quality among the employees, resulting in lower work performances and engagements while contributing to higher interpersonal conflicts. The findings concluded that smartphone usage before sleep increases the prospects of employees to be less productive, less engaged, and have more workplace conflicts. The findings warrant the continued managerial as well as academic research attention, as the smartphones are now used by many organisations to run businesses as well.
对数字设备（如智能手机）的过度使用和过度依赖，已被视为一种日益严重的国际“流行病”。对小工具，尤其是用于个人和公务的智能手机的依赖增加，也给个人用户带来了许多不利影响。因此，了解智能手机使用对人类的负面影响至关重要。因此，本研究旨在调查睡前使用智能手机对工作绩效、人际冲突和工作投入的影响，以及睡眠质量在员工中的中介作用。采用横断面研究设计，对315名员工作为受访者进行了基于问卷的实地调查。结果证实了睡前使用智能手机对睡眠质量有负面影响。与此同时，睡眠质量对工作绩效、工作投入和人际冲突的影响在统计上也被证明是显著的。关于睡眠质量的中介作用，经验证据表明，睡眠质量在睡前使用智能手机与工作绩效和人际冲突之间起中介作用。研究结果显示，睡前使用智能手机会降低员工的睡眠质量，导致工作绩效和投入度下降，同时加剧人际冲突。研究结果得出结论，睡前使用智能手机会增加员工工作效率低下、工作投入度低以及职场冲突更多的可能性。这些发现值得管理层和学术研究持续关注，因为现在许多组织也使用智能手机来开展业务。
