Tweens Always on Phones at Greater Risk of Mental Health Issues: Study

A study of over 8,000 US adolescents links addiction-like screen use to increased risks of depression, sleep issues, suicidal behaviors, and substance initiation one year later.

  • On February 12, 2026, the American Journal of Preventive Medicine published new research reporting problematic use of mobile phones, social media, and video games among US early adolescents ages 11–12.
  • Screen use rises rapidly during early adolescence , a critical period when mental health, sleep problems and substance use often begin to emerge, prompting focus on problematic, addiction-like patterns to address gaps flagged by the US Surgeon General.
  • Problematic mobile phone and social media use were linked to higher depressive symptoms, conduct problems, suicidal behaviors, sleep disturbance, and substance initiation one year later, while video game use showed stronger ties to suicidal ideation and sleep disruptions.
  • The results underpin the necessity of interventions tailored to early adolescents, a critical period for psychological vulnerabilities, and researchers say these findings could shape health policy and clinical practice.
  • Researchers analyzed over 8,000 participants in the Adolescent Brain Cognitive Development Study, finding stronger links than prior screen-time research and urging digital platforms and families to reduce addictive features.
