Addictive patterns of phone and social media use in early adolescence have emerged as a stronger marker of suicide risk than time spent on screens alone.
That finding reframes everyday phone habits as a mental health signal that quietly intensifies during the years when risk rises fastest.
Addiction signs beat screen time
Evidence for this shift came from tracking how children’s relationships with screens changed as they moved toward adolescence, rather than tallying daily hours.
Working with long-term data, Yunyu Xiao at Weill Cornell Medicine documented how growing loss of control over screen use aligned with later mental health harm.
Many children who appeared low risk at age ten developed escalating addictive patterns over the following years, a change that would not show up in a single snapshot.
That delayed emergence sets a boundary on what simple time limits can reveal and points toward why the next section must look closely at how craving itself takes hold.
What addictive use means
Addictive use refers to screen behavior that feels hard to control even when it causes distress or problems, and it can creep in before a parent notices.
Within a long-running national study, researchers asked children about urges, distress, and feeling driven to use screens more often.
Some questions focused on distress without a phone or using games to escape problems, reflecting emotional dependence that can worsen mood over time.
That focus matters because a child can log many hours online for homework or friends without feeling trapped.
Screen time habits climb
Instead of treating every kid the same, the team sorted children into patterns of low, high, or rising addictive use.
Over four years, those patterns separated clearly as children moved from ages 11 to 15.
About 31.3 percent showed increasing addictive social media use, and 24.6 percent showed increasing mobile phone use over that period.
Those rising groups started near low levels, so a simple snapshot at age ten missed many kids who later struggled.
Link to suicide risk
A CDC report lists suicide among the leading causes of death for U.S. kids ages 10-14.
By the fourth year of follow-up, 5.1 percent of participants reported suicidal behaviors and 17.9 percent reported suicidal ideation, meaning serious thoughts about suicide.
After adjusting for baseline mental health, increasing addictive social media use was linked to 2.14 times the risk of suicidal behaviors.
Because the study observed kids rather than assigning habits, it could not prove that screens caused those outcomes.
Mental health varies
Not every struggle looked the same, because some kids turned distress inward while others acted it out at home or school.
Parents reported internalizing symptoms, which show up as anxiety or depression, along with separate measures of outward behavior problems.
High addictive video game use matched the biggest difference on those internal scores, about 2.03 points higher than low use.
These changes were small on average, but they pointed to extra strain on children who were already at risk.
Screen time alone falls short
Minutes on a device did not predict which kids later struggled, even though time limits dominate most family rules.
Baseline reports of weekday and weekend use, outside schoolwork, were not linked to suicide-related outcomes in the analyses.
When addictive patterns were included, screen time still added little information, suggesting that it is what use feels like matters most.
A child can spend long hours texting or watching shows and stay fine, but compulsion raises a different flag.
Unequal burdens in the data
Addictive use patterns did not spread evenly, and the highest-risk groups overlapped with communities facing more daily stress.
High addictive trajectories appeared more often among Black and Hispanic youths and among families with lower income or less parental education.
Those differences likely mixed opportunity and vulnerability, because households under pressure may rely on screens for calm and connection.
The results warned against blaming kids, since social forces can shape habits long before any child can fully self-regulate.
Early warning signs
Health officials have urged caution, noting that evidence about long-term safety for young users remains limited.
“At this time, we do not yet have enough evidence to determine if social media is sufficiently safe for children and adolescents,” wrote Dr. Vivek Murthy, the U.S. Surgeon General.
Families can watch for rising irritability, sleep loss, or panic when access ends, because withdrawal can make the body feel on edge.
When those signs appear alongside isolation or talk of self-harm, a clinician should step in quickly and directly.
Healthier screen use
A NewYork-Presbyterian summary urged families to watch for addiction-like signals instead of chasing perfect screen time rules.
“Our study is shifting the paradigm and focus of the conversation from screen time to the signs of addiction,” said Xiao.
Repeated check-ins can help because small changes in mood, sleep, or schoolwork often appear before more serious problems.
Rules work best when adults model them too, since kids track fairness and consistency as closely as any limit.
A new mental health lens
Collectively, the findings linked youth mental health risk to addictive patterns of use rather than simple screen exposure.
Better screening, honest family boundaries, and more research with objective phone data could clarify who needs help and when.
The study is published in JAMA.
