  1. Attention fragmentation and emotional distress: a mixed-methods study of social media use among Indian adults aged 18-45 years

    Bayaskar, S.; Sharma, D.
    BMC Psychology, 14, 1080

    This survey of 582 Indian adults found that people who spent more time on social media were more likely to have scattered, broken attention. People with scattered attention also reported more anxiety and low mood. Many described jumping between Reels and WhatsApp as leaving their mind cluttered. The study shows a link, not that social media causes these problems.

  2. Digital gratification: short video consumption and mental health in rural China

    Zhang, C.; Zhu, B.
    Frontiers in Public Health

    This study used longitudinal data to examine how frequent short video use is linked with mental health among rural residents in China. It reports a short-term improvement in mental health in the first year of exposure, but says this effect fades later. The reported improvements appear to be linked to entertainment and access to information rather than greater social interaction.

  3. Feeds, feelings, and focus: A systematic review and meta-analysis examining the cognitive and mental health correlates of short-form video use

    Nguyen, L.; Walters, J.; Paul, S. et al.
    Psychological Bulletin, 151(9), 1125–1146

    This study combined the results of 71 earlier studies with nearly 100,000 people. Across them, people who watched more short videos tended to have weaker attention and self-control, and somewhat more stress and anxiety. It found no link with body image or self-esteem. These are links seen across studies; they do not prove that short videos cause the problems.

  4. A cross-lagged analysis of the relationship between short video overuse behavior and depression among college students

    Zhang, D.; Yang, Y.; Guan, M.
    Frontiers in Psychology, 15, 1345076

    This study surveyed 331 Chinese college students twice, two months apart. Students who overused short videos at the start were more likely to have more signs of depression two months later; depression at the start did not predict later overuse. It is a small study and shows a possible risk, not proof of harm.

  5. The relationship between short-form video use and depression among Chinese adolescents: Examining the mediating roles of need gratification and short-form video addiction

    Zhu, C.; Jiang, Y.; Lei, H. et al.
    Heliyon, 10(9), e30346

    In a survey of 1,302 high-school students in China, the amount of time spent watching short videos was only weakly linked to depression. Feeling unable to stop watching was much more strongly linked to it. The study shows links, not causes, and the link could run either way.
