Screen Time and ADHD in Children: What Does the Research Say?

One of the questions asked most often by families of a child with ADHD is this: the child will not let go of the screen, did the screen cause the ADHD?

This article covers what the research does and does not say on this question and how the routine at home can be set up. For the general framework there is the article on whether screen time causes ADHD; here we look at the side of the child and the parent.

What is known

The meta-analysis by Nikkelen and colleagues found a small but significant relationship between media use and ADHD-related behaviors. The adolescent study by Ra and colleagues, published in JAMA, reported that in teenagers who used digital media at high frequency the likelihood of later showing ADHD symptoms rose slightly.

These two findings do not say that screens cause ADHD. They say that the two tend to be seen together and that the relationship is not large. Observational studies cannot prove causation.

What is accepted as the main cause of ADHD is genetic predisposition and a difference in brain development. The consensus statement of the World Federation of ADHD summarizes it this way too. Environmental factors play a role, but that screens in themselves cause it is not supported by scientific evidence.

The direction of the relationship

The relationship may run in both directions:

• Screen use may be increasing symptoms: by disrupting sleep, reducing movement and taking the place of activities that require attention.
• A child who finds attention and impulse control hard may be drawn more to screens that give fast rewards and instant feedback.
• A third factor, for example stress and disorder in the family, may be increasing both.

In most children these three directions may be operating together. The practical conclusion for families: instead of looking for the screen as a culprit, manage the screen's effect on other areas of the day.

Why screens are so attractive

Games and short videos offer high arousal, instant feedback and constantly changing content. Compared with a school and home day that requires waiting, boredom and delayed reward, the screen is noticeably "easier" for a child with ADHD.

That is why letting go of the screen is also hard. The anger and objection at the moment of letting go are most often not character or stubbornness but a difficulty with regulation. For the anger side you can look at the article on anger outbursts in a child with ADHD.

Where screens really do harm

More than screen time itself, these three areas matter:

Sleep. A screen used before bed can delay falling asleep. Since sleep problems are already common in children with ADHD, these two headings overlap. The details are in the article on sleep in a child with ADHD.

Movement. If hours spent in front of a screen take the place of movement and outdoor play, the indirect effect grows. The article on sports and movement describes this link.

Transitions. The moment of turning off the screen is the place in the day with the most conflict. The routine needs to be set up with this in mind.

A routine that works at home

There is no single right rule, but these principles are workable for most families:

• Let the rules be clear and predictable. Such as "half an hour after dinner on weekdays." A written or pictured plan helps you avoid bargaining every day.
• Include the child in setting up the rule. Compliance is higher with rules chosen together.
• Announce the end in advance. "Five minutes left" and then a timer. A surprise shutdown brings an outburst.
• Have a clear next activity after the screen. If a gap is left, they go back to the screen.
• No screens in the bedroom or at the dinner table. Among the easiest limits to apply, for sleep and family time.
• The parent sets an example too. In a home where the rule is set for the child while the parent constantly looks at their phone, the rule is hard to establish.

A screen can also be a tool

Not every screen is the same. The difference between a puzzle or drawing app used together and short videos scrolled for hours is large. Using a timer or a visual plan while studying is also a useful use of a screen.

For this reason, instead of "screens are bad," the question "what is this screen doing for us" is a more productive place to start.

When to consult a specialist

If the child shows extreme anger and reaction when kept away from the screen, if their sleep and school functioning have markedly deteriorated, if no interest is left in any activity other than the screen, you need to talk to a child and adolescent psychiatrist. A screen problem is often a side sign of another underlying picture, for example anxiety or depression.
