研究用生态瞬时评估法调查了334名白领在工作中的非工作社交媒体使用，发现虽然总体上与较低的工作投入相关，但每小时内的使用反而能提升下一小时的工作投入，可能起到微休息的作用。
Non-work social media use at work has seen a dramatic increase in the last decade and is commonly deemed counterproductive work behaviour. However, we examined whether it may also serve as a micro-break and improve work engagement. We used ecological momentary assessment across 1 working day with up to 10 hourly measurements in 334 white-collar workers to measure non-work social media use and work engagement, resulting in 2235 hourly measurements. Multilevel modelling demonstrated that non-work social media use was associated with lower levels of work engagement between persons. Within persons, non-work social media use was also associated with lower concurrent work engagement. However, non-work social media use was related to higher levels of work engagement 1 hour later. While more extensive non-work social media use at work was generally associated with lower work engagement, our advanced study design revealed that the longer employees used social media for non-work purposes during 1 working hour, the more work engaged they were in the subsequent working hour, suggesting that employees turn to social media when energy levels are low and/or when they (temporarily) lose interest in their work. This behaviour may serve as a break, which in turn increases work engagement later during the day.
