"Fully recharged" evenings? The effect of evening cyber leisure on next-day vitality and performance through sleep quantity and quality, bedtime procrastination, and psychological detachment, and the moderating role of mindfulness.

Aligning with the recovery perspective, we propose a dual-path model to illustrate the effects of employees' evening cyber leisure on next-day work outcomes, namely, psychological vitality and performance. We argue that evening cyber leisure has contradicting effects on next-day performance and vitality through its effects on bedtime procrastination and psychological detachment, and in turn, sleep quantity and sleep quality. We also propose that trait mindfulness acts as an important boundary condition of the indirect effects of evening cyber leisure. We used an experience sampling methodology to collect 3 surveys per day for 10 days from 155 R&D employees of a biotech company. Our findings suggest that cyber leisure has a negative indirect effect on sleep quantity and sleep quality via bedtime procrastination, and a positive indirect effect on sleep quantity and sleep quality via evening psychological detachment. Additionally, sleep quantity was positively associated with performance, and sleep quality was positively associated with psychological vitality. Lastly, as trait mindfulness increased, the negative impact of cyber leisure on bedtime procrastination was mitigated, and the positive impact of cyber leisure on psychological detachment was enhanced. Theoretical and practical implications specific to the use of cyber devices for workplace recovery are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
