Study Links Screen Addiction to Teen Depression and Anxiety

During summer break, teens often turn to social media and video games to cope with boredom. While parents have long focused on balancing screen time with outdoor activities, a new study published in JAMA (The Journal of the American Medical Association) suggests that the core issue lies in screen addiction, not merely the duration of use. Addictive behaviors include compulsive engagement, inability to disengage, and anxiety when not using screens. The study found that about 30% of 11-year-olds are addicted to social media, and 40% to video games.

Most research has historically assessed problematic screen use by measuring total screen time. Reports indicate that daily screen use among U.S. teens aged 13–18 rose from 7.2 hours in 2019 to 8.4 hours in 2021. However, the new research highlights that addiction varies by type of screen activity. Longitudinal data from the Adolescent Brain Cognitive Development (ABCD) Study show that video game addiction tends to manifest early—40% of 11-year-olds showed signs of addiction that persisted for years. In contrast, social media addiction tends to increase with age. Teens with screen addictions are more likely to experience depression, anxiety, aggression, and suicidal tendencies, with notable differences across gender and racial groups.

A teen’s prefrontal cortex is still developing, making it harder to resist dopamine-driven rewards. Social media platforms exploit this vulnerability with features like likes and comments, delivering random, casino-like rewards that heighten addictive potential.

While total screen elimination is unrealistic, the American Academy of Pediatrics recommends clear boundaries: designate screen-free zones such as bedrooms and dinner tables, prioritize outdoor activities, and encourage parental role modeling. In severe cases, temporary removal of devices may be necessary, though initial resistance is common.

Researchers emphasize that the addictive design of social media is a feature—not a flaw—of its business model and call for regulatory action. California has already passed legislation restricting addictive content and nighttime notifications for minors. Schools are also reevaluating device usage, with some experimenting with “phone-free days.”
