New Delhi: Digital media, especially social platforms, shows a consistent link with poorer mental health outcomes in children and adolescents, even though the effects on each individual appear modest. Over time and across large populations, these small shifts can add up to meaningful impacts on emotional, behavioural, and academic development.
A major analysis published online in the JAMA (Journal of the American Medical Association) examined more than 150 studies involving more than 363,000 participants aged 2 to 19. Unlike earlier “snapshot” studies, this research followed children over time, offering a more reliable view of how digital habits shape development. While it stops short of proving causation, the consistency of the findings suggests that digital media plays a measurable and accumulating role in young people’s lives.
The findings do not establish causation. Yet their persistence across studies suggests that digital media, particularly social platforms, plays a measurable role in shaping young lives, often in ways that are not immediately visible but accumulate over time.
“We found that children were at a broader risk for difficulties with their social and emotional development,” said study author Samantha Teague, senior research fellow in the department of psychology at James Cook University in Australia. “And we saw higher rates of depression and anxiety across the board,” she notes.
“Overall, the associations were small to moderate. They reflected modest shifts in risk at the individual level, which is not unusual in longitudinal studies covering sizable groups.”
The small effects “can accumulate over time and at scale, contributing to meaningful shifts” at the population level.
Engagement Type Matters
A key takeaway from the report published in JAMA is that the long-standing focus on total “screen time” is increasingly outdated. What matters more is the nature of engagement: what children are doing online, not just how long they spend.
The analysis separates different forms of digital use, including video games, messaging platforms, and educational content. The results vary. Video gaming, for instance, shows a complex pattern, associated with both increased aggression and improved attention and executive functioning.
Social media, however, stands apart. It is the only category consistently linked to negative outcomes across emotional, behavioural, and academic domains. From anxiety and depression to lower self-esteem and substance use, its influence appears both broad and deep.
“It was associated with worse outcomes across every single domain we observed,” Teague said of the data, which showed that higher social media engagement was linked to behavioural problems, self-injury, lower self-perception and academic achievement, and higher rates of substance use. “It’s concerning, the scale of what we found.”
Studies conducted after 2012, when smartphones were widespread and device-driven platforms became more immersive, showed more intense negative correlations, says the report. Social media and depression links were stronger in early adolescence, in the 12- to 15-year-olds, than in elementary-aged children, it adds.

Addiction Question and Platform Design
The report also highlights a growing concern among researchers: the addictive design of modern social media platforms. Features such as infinite scrolling, algorithm-driven feeds, and constant notifications are engineered to maximise user engagement, often at the cost of well-being.
This has shifted the conversation from individual responsibility to structural accountability. For years, families were expected to manage children’s digital habits on their own. Increasingly, attention is turning to the tech companies that shape these environments.
Legal developments reflect this shift, with courts in the United States holding major platforms accountable for creating addictive systems linked to mental health harms. Meanwhile, governments are experimenting with age restrictions and access controls, though early evidence suggests these measures are difficult to enforce and may have unintended consequences.
In fact, the most powerful relationship in Teague’s meta-analysis was social media’s link to more problematic internet use, or media addiction, later.
“That pattern differed from what we saw with video games,” said Yunyu Xiao, assistant professor of population health sciences at Weill Cornell Medical College, who researches addictive screen use trajectories. “The reason we cannot group all screen time together is because it would obscure these important differences.”
“I see a lot of parallels to core addictive symptoms like cravings and withdrawal. Those are aspects we’re starting to see with social media use among even young adolescents.”
What Next for Families, Policymakers
In the absence of sweeping reform, the responsibility for managing digital exposure continues to fall on families, clinicians and educators. The report suggests that discussions about screen use should become routine in clinical settings, much like conversations about sleep, diet, and physical activity.
Experts emphasise that a nuanced approach is essential. Blanket bans may not work, and overly simplistic messaging risks alienating young users. Instead, the focus should be on understanding context — what children are consuming, how they are engaging, and how it affects them.
At the same time, the report identifies a critical gap in research: the lack of evidence on positive digital experiences. While young people often describe social media as a space for connection and creativity, these benefits remain underexplored.
“Screen use should be part of routine assessment, the same way they ask about sleep and physical activities and diet, especially for adolescents,” Xiao said. “And not just asking how much, but what and how they use it.”
“Even though we know there are risks associated with drug use, if you start your encounter by saying drugs are bad for you, your patients aren’t going to open up about their substance use. It’s the same thing with social media,” he added.
So, clinicians should still be giving advice and parents should still do their best to protect their children from harm.
