Screen time is both a cause and symptom of kids’ bad behavior, according to new research

Context:

Screen time in children is linked to socioemotional problems like anxiety, depression, hyperactivity, and aggression, with the impact being more pronounced in girls. A meta-analysis of 117 studies highlights that excessive screen time, especially through gaming, causes an increase in socioemotional issues, particularly in children aged 6 to 10. The study suggests that screens are both a cause and a symptom of emotional struggles, as children often use them to cope, which may exacerbate existing problems. Parents are advised to limit screen time, use parental controls, and encourage children to engage in real-life activities to avoid dependence on screens. Setting boundaries and offering alternatives to screen time can support better mental health and emotional regulation in children over the long term, despite potential short-term pushback from the children.

Dive Deeper:

  • Research indicates that increased screen time is associated with socioemotional issues such as anxiety and aggression, with a significant impact observed in girls. Children under age 2 should avoid screen time, while those aged 2-5 should limit it to one hour per day, and older children to two hours.

  • Children who frequently engage with screens often do so to escape emotional difficulties, creating a cycle where screen time both causes and exacerbates these issues. Particularly, boys and children who engage heavily in gaming are at higher risk.

  • The study, while comprehensive, has limitations due to factors like varying parenting styles and socioeconomic status, and it does not isolate the effects of social media specifically on children's mental health.

  • Screens should not be used as a tool for calming children as it hampers their ability to develop emotional regulation skills. This reliance can mask underlying emotional issues, making it harder for children to cope without screens over time.

  • To mitigate these negative impacts, parents are encouraged to set consistent rules regarding screen time, use parental controls to ensure age-appropriate content, and provide educational or purposeful content as alternatives.

  • Parents are advised to be firm with screen time limits, as excessive smartphone or social media use is linked to sleep, attention, and body dissatisfaction issues. Offering attractive alternatives to screen use, such as activities or rewards, can be effective.

  • Understanding that screen time can be both a symptom and a cause of emotional and behavioral problems, parents should be prepared to say no to excessive screen use to promote better long-term mental health outcomes for their children.
