Adolescents who become deeply attached to mobile phones, social media, or video games may face a higher risk of mental health problems — including suicidal thoughts and behaviours — according to a large-scale, long-term study.

Tracking nearly 4,300 children from the age of nine or ten over four years, researchers shifted the focus away from raw screen time and instead examined signs of compulsive digital use. Young people who struggled to cut back, felt distress without access, or allowed their digital habits to interfere with daily responsibilities were found to have a significantly higher chance of developing emotional and behavioural challenges as they got older.

By the end of the study period, those with persistently high or increasing compulsive phone or social media use were roughly twice as likely to report suicidal behaviour compared to peers with stable, low-risk use. Similar patterns were observed in video game use: over 40% of participants landed in a high-risk group, with notable links to anxiety, depression, aggression, and rule-breaking behaviours.

Crucially, the researchers noted that it wasn’t the sheer number of hours online that posed the greatest threat. Instead, it was the emotional and behavioural patterns surrounding technology use — the signs of dependence and loss of control — that were more strongly associated with negative mental health outcomes.

To better understand these risks, the study grouped participants by their usage patterns rather than relying on average screen time [1]. For mobile phone use, about half of the children displayed signs of addictive behaviour early on that persisted over time. Another quarter developed these patterns as they aged. In the realm of social media, around 41% of children followed a similar high-risk or escalating trajectory.

These concerning patterns were linked to a two- to threefold increase in the likelihood of suicide-related thoughts or behaviours and broader emotional difficulties, suggesting that the way young people engage with digital platforms can shape their mental health trajectory.

While the study stops short of proving that excessive digital use directly causes mental illness, it does highlight that compulsive digital behaviour might reflect deeper struggles — or even worsen them. The lure of always-on access, algorithm-driven feeds, and instant social feedback can make it particularly tough for vulnerable teens to step away.

Experts say these findings should prompt parents, educators, and policymakers to look beyond screen time caps alone. Approaches borrowed from addiction treatment could be more effective in addressing the root causes of dependence, rather than simply limiting use.

At a time when concerns over youth mental health and debates over smartphone policies are rising, this research adds important nuance: it’s not just about how long teens are online, but how and why they use digital platforms that truly matters.
