Recent research published in Development and Psychopathology has revealed that how children use screens may matter more than how long they use them when it comes to mental health. Behaviors such as obsessing over screen time or becoming upset when denied access were more strongly linked to depression, anxiety, and self-harm than total hours spent on devices.
Parents and experts have debated whether screen time is harming kids’ mental health. Some studies have suggested that more time on phones and tablets leads to worse outcomes, while others have found little evidence of harm. But researchers are now shifting focus to how children behave around screens – what they call “problematic media use.”
Problematic media use includes behaviors such as sneaking in screen time, becoming emotionally dysregulated when denied access, or using screens to cope with negative emotions. These patterns may interfere with family life and signal deeper emotional struggles.
To better understand these behaviors, a research team led by Lauren Eales from the University of Minnesota in Minneapolis analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study. The ABCD Study is a large national project tracking 10,052 children aged 10 to 13.
The team scrutinized parent-reported screen time and problematic media use, and compared these to measures of mental health, including depression, anxiety, behavioral issues, suicidal thoughts, and self-injury.
The results were clear: problematic media use was a much stronger predictor of mental health concerns than screen time. Children who showed more problematic behaviors around screens were significantly more likely to experience emotional and behavioral problems. They were also more likely to report suicidal thoughts and engage in self-harm.
Importantly, these patterns held across nearly all racial and ethnic groups and for both boys and girls. While screen time had some associations with mental health, its effects were smaller and less consistent. For example, screen time did not predict suicidal ideation or self-injury, while problematic media use did.
The study also found some demographic nuances. For instance, Hispanic/Latine youth with higher screen time showed fewer externalizing symptoms (outward behaviors like aggression, defiance, or acting out), and multiracial youth with high screen time had higher emotional problems. But overall, problematic media use was the more reliable indicator of mental health risk.
Eales and colleagues emphasised the key message of their study, “it is more important to focus on how screens impact youth’s daily lives, rather than how much time they engage with the screen.”
Researchers caution that some limitations remain. Parent reports may blur the line between problematic media use and general behavioral issues, and screen time measures may not capture the full picture. Additionally, small sample sizes in some racial groups mean those findings should be interpreted carefully.
The study, “Screen time, problematic media use, and clinical concerns in the ABCD Study: Differences by sex and race/ethnicity”, was authored by Lauren Eales, Andrea Wiglesworth, Kathryn R. Cullen, and Bonnie Klimes-Dougan.
