A groundbreaking new study challenges common assumptions about screen time and youth mental health, revealing that it’s not the amount of time teenagers spend on digital devices that increases their risk of suicidal thoughts and behaviors, but rather the development of addictive use patterns.
This large-scale, longitudinal research, published in the journal JAMA, tracked nearly 4,300 young people across the U.S. from ages 9-10 through age 14. Led by researchers from Weill Cornell Medicine, Columbia University, and University of California, Berkeley, the study moved beyond simply measuring total hours spent online. Instead, it focused on understanding the nature of screen engagement over time, specifically looking for signs of problematic or “addictive” use.
Screen Time vs. Screen Addiction: A Critical Difference
The study clearly demonstrated that the total amount of time spent on social media, mobile phones, or video games at age 10 was not associated with future suicide-related outcomes or mental health issues. This finding directly contradicts the widespread concern that simply limiting screen minutes is the primary solution.
What did matter was how youth engaged with screens, characterized by behaviors indicative of addiction, such as:
Feeling unable to stop using a device despite trying
Experiencing distress, anxiety, or upset when not online or using screens
Using screens specifically to escape from real-life problems or negative feelings
Losing track of time while using devices
Using screens so excessively it negatively impacts schoolwork or other activities
Addictive Patterns Strongly Linked to Risk
Using sophisticated modeling, the researchers identified distinct patterns, or “trajectories,” of addictive screen use over the four years. By age 14, significant proportions of teens showed high or increasing levels of addiction: nearly one in three for social media, roughly a quarter for mobile phones, and over 40 percent for video games.
The core finding was stark: adolescents who followed these high or increasing addictive use trajectories were significantly more likely to report suicidal thoughts and behaviors compared to those with low addictive use.
Teens with increasing addictive use trajectories for social media or mobile phones showed a two to three times greater risk of suicidal thoughts and behaviors.
Specifically, increasing addictive social media use was associated with a risk ratio of 2.14 for suicidal behaviors, while high-peaking use had an even higher risk ratio of 2.39.
Beyond suicide risk, these addictive patterns were also strongly associated with other mental health challenges, including:
Internalizing symptoms: Anxiety and depression
- Externalizing symptoms: Aggression and rule-breaking
- Identifying addictive patterns: Recognizing the signs of compulsive use, distress when offline, or using screens to escape.
- Understanding the “why”: Exploring the underlying reasons for excessive or problematic screen use, which may point to existing anxiety, depression, or other stressors.
- Seeking professional evaluation: If signs of screen addiction are present, professional advice is essential, as simply removing screens may not address root causes.

The study noted subtle differences: high video game addiction trajectories were linked to larger differences in internalizing symptoms, while increasing social media addiction trajectories showed larger differences in externalizing symptoms.
A Paradigm Shift in Understanding Screen Impact
These findings suggest a crucial paradigm shift is needed in how parents, educators, and clinicians address youth screen use. Experts involved in the study emphasize that conversations must move beyond simple time limits to focus on the more complex factors underlying addictive engagement.
Focusing solely on banning or limiting use based on duration, as some interventions have attempted (like limiting phone use during school), may not be effective and could even potentially reinforce addictive behaviors in those already struggling.
Instead, the focus should be on:
What This Means for Parents and Educators
The study highlights the value of repeated assessment for addictive screen use patterns, especially as children enter early adolescence, even if their initial use seems low. Concerning trends can develop over time and may not be predictable from a single assessment.
While this study demonstrates a strong association (linking higher addiction trajectories to roughly double the near-future risk of suicidal behavior), it acknowledges it does not definitively prove causation. However, the significant correlation underscores the urgency of addressing addictive screen use patterns as a potential risk factor for serious mental health outcomes.
Researchers suggest exploring intervention strategies effective for other types of addiction in children and adolescents might be relevant for addressing problematic screen use. Future work aims to profile children at highest risk based on demographic factors and develop interventions targeting addictive behaviors early to potentially mitigate suicide risk.
In conclusion, this research provides critical evidence that the danger isn’t the clock on the screen, but the grip it holds on a young person’s mind and behavior. Recognizing and addressing the signs of screen addiction is a vital step in supporting adolescent mental health.
