Problematic TikTok Use and Its Association with Poor Sleep: A Cross-Sectional Study Among Greek Young Adults

Year: 2025

Type: article

Abstract: Background: TikTok use is constantly increasing, especially among young adults. Although there is a negative association between problematic TikTok use and users’ health, no study until recently has investigated the association between TikTok use and poor sleep. Thus, this study aimed to evaluate TikTok use among young adults and its association with poor sleep. Methods: A cross-sectional study was conducted in Greece. The study sample included 361 adults aged 18–35. A convenience sample through social media was employed. Levels of TikTok use among participants were measured with the TikTok Addiction Scale (TTAS). Results: The mean time of TikTok use was 2.4 h (SD; 1.6), while the mean TTAS score was 2.3 (SD; 0.7). The 11.6% of the participants are problematic TikTok users. A negative correlation between the duration of night sleep and levels of TikTok addiction was found. Also, a positive correlation between sleepiness in work or class and levels of TikTok addiction was found. Furthermore, younger ages were correlated to increased levels of TikTok addiction and time on TikTok. The levels of TikTok addiction were higher among females. Conclusions: This study suggested that higher levels of TikTok addiction and TikTok use were correlated with reduced duration of night sleep and increased sleepiness in work/class.
