A British study of 25,000 adolescents over three years finds no evidence that screen time leads to increased anxiety or depression.Neither active nor passive use of social media shows correlation with worsened mental health.Researchers used advanced statistical method that distinguishes between individual differences and changes over time.Large British study followed adolescents for three years
Researchers at the University of Manchester have conducted one of the most comprehensive studies to date on the relationship between digital technology and adolescent mental health. The study followed 25,629 British adolescents aged 11 to 14 over three school years, from autumn 2021 to autumn 2023.
Participants reported how much time they spent on social media such as TikTok, Instagram and Snapchat during a normal weekday. They also answered questions about how often they played computer or console games and responded to questions about their feelings and wellbeing.
The results show that there is no evidence that more time on social media or more frequent gaming leads to increased symptoms of anxiety or depression among either girls or boys.
The method enabled more reliable conclusions
The study, published in the Journal of Public Health, used an advanced statistical method called random intercept cross-lagged panel model. This method makes it possible to distinguish between stable differences between individuals and changes within the same individual over time. This is important because previous research has often conflated these two types of effects, which can lead to incorrect conclusions.
The researchers also controlled for factors such as gender, ethnicity, socioeconomic background and any special educational needs. Of the 25,629 participants, 17 percent had special educational needs, 29 percent were eligible for free school meals and 34 percent belonged to minority groups.
Active or passive use made no difference
The researchers also examined whether the way adolescents use social media matters. Participants were asked to estimate how much of their time they spent actively participating, such as chatting with others and posting pictures and videos, compared to passively scrolling through feeds and looking at others’ posts.
The analyses showed that neither active nor passive use of social media had any correlation with the development of mental health problems. This result challenges the theory that passive scrolling would be more harmful than active participation.
Gaming may decrease when adolescents feel unwell
The study also found an unexpected correlation among boys. Those who had more symptoms of mental health problems played fewer games the following year. The researchers suggest this may be because a common symptom of depression is withdrawing from activities one previously enjoyed.
Another possible explanation is that parents of these adolescents may have limited their gaming time due to concerns about the relationship between gaming and mental health. Previous research shows that parents with negative attitudes towards games tend to be more controlling and that parents often set stricter gaming rules for boys than for girls.
Researchers call for changed focus
The researchers behind the study emphasize that their results do not mean that everything that happens online is harmless. Hurtful messages, pressure from social media and extreme content can still affect adolescents’ wellbeing negatively. But focusing solely on screen time is not helpful.
Qiqi Cheng, lead author of the study, says the results do not support the idea that time on social media or gaming leads to mental health problems. The picture is far more complex than that.
Neil Humphrey, co-author, says that adolescents’ choices around social media and gaming may be shaped by how they feel, but not necessarily the other way around. Instead of blaming technology, society needs to pay attention to what young people actually do online, who they are in contact with and how much support they feel in their daily lives.
