Identifying forms of after‐hours information communication technology use and their role in psychological detachment: An episodic approach
研究通过事件日记法调查498名员工下班后使用不同ICT（如邮件、聊天软件、电话）对心理脱离和任务效率的影响，发现所有ICT使用都降低心理脱离，但邮件和聊天软件影响最大，而同步通信（如电话）仅在组织期望高响应时提升效率。
Abstract Employees increasingly conduct work outside of traditional work hours via information communication technologies (ICTs). There is a need to understand how after‐hours ICT use relates to well‐being, given that such connectivity has become unavoidable. We implement an episodic, event‐contingent design to evaluate the association between different ICT media (i.e., e‐mail, phone call, chat app, short message service) and the within‐person outcomes of psychological detachment as partially mediated by task productivity. A daily diary survey was collected over three consecutive workdays to capture after‐hours ICT use. Daily surveys were completed by 498 individuals, with a total of 1494 episodes being captured of after‐hours work ICT engagement. Our results indicate that while engagement with any form of ICT after hours reduces psychological detachment, email and chat apps are associated with the lowest levels of psychological detachment. Moreover, whereas the use of asynchronous ICT has positive main effects on episode‐related task productivity, the use of synchronous ICT (e.g., phone) only enhances episode‐related task productivity when there are high organizational expectations for employees' responsiveness after hours.
