We live in a digital world, so children are exposed to screens in many aspects of their lives—from schoolwork to entertainment to social connection. As children’s screen use has increased, researchers, clinicians, parents, and educators have raised growing concerns about attention, focus, and attention deficit hyperactivity disorder (ADHD)-related behaviors, such as inattention or impulsivity (Malesu, 2025). A recent study by Malesu (2025), in which more than 8,000 children from age 9 to early adolescence were followed, adds an important perspective to this conversation and suggests that screen time use does not affect children in the same way. Unlike television or video games, higher social media use was associated with gradual increases in children’s difficulty sustaining attention over the 4 years researchers followed them (Malesu, 2025).
Much of the existing research on screen time has treated all digital activities as equal modes of interaction and has grouped all virtual activities together, from texting and social media to gaming and television viewing. The Malesu (2025) study takes a more detailed approach and uses participants from the Adolescent Brain Cognitive Development (ABCD) Study (2023), which followed more than 11,000 children in the United States from age 8 to early adolescence. In the ABCD (2023) study, Brown and colleagues tracked how much time children typically spent participating in different types of digital activities, including social media, video games, and television or videos (Brown et al., 2023). Then, researchers looked at whether the amount of time children spent on social media, video games, and watching television was linked to changes in their attention and hyperactivity symptoms over several years. These data were derived from parent reports (Malesu, 2025).
Study Findings
The Malesu (2025) study found an important pattern. Children who spent more time on social media showed small but steady increases in attention problems over time (Malesu, 2025). This pattern was not seen with video game usage or television viewing (Malesu, 2025). Malesu also examined the causal flow between social media use and attention problems. The results suggested that children weren’t turning to social media because they were already struggling with attention, but, instead, higher social media use usually occurred first, and increases in attention problems followed (Malesu, 2025).
One possible reason social media stood out, compared to video games and television, may be related to how these platforms are designed. Unlike television or many video games, social media is built around and demands constant interaction. Notifications, messages, and endless scrolling encourage youth to switch their attention quickly and often, which can make staying focused for long periods of time more difficult. Over time, regularly using apps designed to create ongoing engagement may influence how children manage their attention, especially during a stage of brain development when focus and self-control skills are still growing, which occurs during adolescence (Malesu, 2025).
The Malesu study reveals that social media use may have small effects on shaping individual children’s behavior. Social media use, alone, is unlikely to cause major attention problems or lead directly to an ADHD diagnosis (Malesu, 2025). However, when large numbers of children are affected, even if the impact is small for each child, the impact can be cumulative. For example, small increases in attention difficulties across many children could mean more students struggling in school, feeling overwhelmed by tasks that require sustained focus, or experiencing attention challenges that become more noticeable over time (Malesu, 2025).
Takeaways for Parents
For parents, findings from the Malesu (2025) study may offer a more balanced way to think about screen time usage:
- Social media does not cause ADHD. The study suggests that social media use does not directly cause ADHD. In addition, this study put forth that screen use is not inherently harmful.
- Not all screen time usage is the same. Social media use may require different levels of attention than watching television or playing many types of video games.
- Small effects can add up. While the impact on one child may be modest, widespread increases in attention difficulties can build and affect many families and classrooms.
- Timing matters. Limiting social media use during homework time, family time, and before bed may help support a child’s focus and sleep.
- Balance is key. Engaging in healthy sleep, physical activity, and face-to-face interactions and receiving emotional support play important roles in children’s attention abilities and overall well-being.
- Open conversations are powerful. Talking with children about how engaging in social media use makes them feel can be more effective than only implementing rules and restrictions.
As families navigate an increasingly digital world, they need to remain aware of their children’s screen usage activities and set and enforce thoughtful boundaries for digital activity use. Paying attention to how much time children spend on screens and how they use them can help support children’s ability to focus, learn, and thrive.
