Abstrakt

In the present ambulatory diary study, we focus on a highly topical and wide-spread behavior: late-night use of mobile devices (e.g., smartphones, tablets). Using a daily process approach and building on the two-process model of sleep regulation and the effort-recovery model, we propose that day-specific late-night use of mobile devices is related to day-specific diminished subsequent sleep and that diminished sleep, in turn, weakens the experience of positive mood the next day. Further, we propose that affective consequences of sleep are more pronounced for people who experience circadian misalignment. Circadian misalignment arises for people who sleep in misalignment with their biological preferences owing to obligations, such as their work schedules. Over the course of 8 consecutive days, we gathered 2 daily questionnaires and ambulatory assessments of sleep with wrist actigraphy from 51 employees (resulting in 312 days/units of matched data). Results confirm prevailing concerns about late-night use of mobile devices by showing that on days with longer late-night use of mobile devices, objectively measured subsequent sleep quality was reduced, which was, in turn, related to lower next-day positive mood. This unfavorable chain of events unfolded only for people who experienced circadian misalignment beyond a certain extent.
