Information technology-mediated interruptions have become widespread and ubiquitous in the workplace. However, our understanding of how these interruptions and individuals’ interruption processing mechanism impact individuals’ performance, especially psychological performance, is still limited. Leveraging Conservation of Resources Theory, this study focused on two types of IT-mediated information interruptions (congruent and incongruent) and examined the moderating effects of different process mechanisms on the relationship between information interruptions and individuals’ interruption overload. A multi-methods research design was conducted in this study: a qualitative study with 20 interviews in Study 1 and a quantitative study with 345 surveys in Study 2. The results show a positive indirect effect of IT-mediated information interruption on emotional exhaustion through interruption overload. Results also review the moderation effects of different processing mechanisms. The findings of this study advance the current understanding of the “dark side” of online information behavior. Additionally, this study provides practical and theoretical implications for both employers and employees on how to process IT-mediated information interruptions in the workplace.

信息技术介导的中断已在工作场所中变得普遍和普遍。但是，我们对这些干扰和个体的干扰处理机制如何影响个体表现，尤其是心理表现的理解仍然有限。利用资源保护理论，本研究集中于两种类型的IT介导的信息中断（一致和不一致），并研究了不同过程机制对信息中断与个人中断超负荷之间关系的调节作用。本研究进行了多方法研究设计：研究1中进行了20次访谈的定性研究，研究2中进行了345次调查的定量研究。结果表明，IT介导的信息中断通过中断超负荷对情绪疲惫具有积极的间接影响。结果还回顾了不同加工机制的调节作用。这项研究的发现推动了对在线信息行为“阴暗面”的当前理解。此外，该研究为雇主和雇员在如何处理工作场所中IT介导的信息中断方面提供了实际和理论上的启示。
