| Popis | Digital media use is widely considered a risk factor for poor sleep across age groups. In recent years, a growing number of intensive longitudinal studies have addressed key limitations of the largely cross-sectional and self-report-based literature by examining day-to-day associations in everyday life and, in some cases, using objective assessments of digital media use and sleep. However, this emerging body of research has not yet been systematically reviewed. The present review therefore synthesizes intensive longitudinal evidence on short-term associations between digital media use and sleep. Two independent reviewers screened records from electronic databases, assessed study quality, and extracted relevant data. Screening yielded 29 quantitative intensive longitudinal studies of non-clinical samples across age groups. Included studies predominantly examined channel-centered indicators of digital media use, such as non-specific, device-specific, or application-specific screen time, and most considered evening media use. The most commonly examined dimensions of sleep health were duration and timing, with fewer studies addressing sleep efficiency, sleep quality, or sleepiness. Overall, the evidence provided little consistent support for short-term associations between digital media use and sleep. When associations were observed, they were generally small, with evening media use showing the clearest pattern of adverse associations. These findings suggest that associations observed in predominantly cross-sectional research are not consistently evident at the day level within individuals and may therefore involve mechanisms operating over different timescales. However, most studies may have lacked the precision needed to distinguish the absence of an association from a small association. Thus, the synthesized evidence does not necessarily establish the absence of day-level within-person associations between digital media use and sleep. |
