More Screen Time For Teens Linked To ADHD Symptoms

Most teens today own a smartphone and go online every day, and about a quarter of them use the internet "almost constantly," according to a 2015 report by the Pew Research Center.

Now a study published Tuesday in JAMA suggests that such frequent use of digital media by adolescents might increase their odds of developing symptoms of attention deficit hyperactivity disorder…

The study followed 2,587 10th graders in schools in Los Angeles county over two years. The teens showed no symptoms of ADHD at the beginning of the study. By the end, teens with more frequent digital media use were more likely to have symptoms of ADHD.

The researchers assessed the students using a standardized questionnaire for ADHD symptoms, including nine symptoms each for inattention and hyperactivity. Students with six or more symptoms in either category were counted as having symptoms of the disorder, based on criteria in the Diagnostic and Statistical Manual Of Mental Disorders.

During the two years of the study, the researchers surveyed the teens every six months and asked them about the frequency of their participation in 14 different kinds of online activities such as texting, sharing on social media and streaming videos or music.

The students reported how many of the 14 activities they did and how often (0, 1-2 times a week, 1-2 times a day, or many times a day). If they did any activity many times, it counted as "high frequency use."

About half of the students said they check social media sites and text many times every day… By and large, students who frequently used six or more activities had a higher likelihood of developing ADHD symptoms.

For instance, among the 51 students who frequently did all 14 online activities, 10.5 percent showed ADHD symptoms over the course of the study. And of the 114 teens who frequently did seven digital activities, 9.5 showed symptoms. In contrast, only 4.6 percent of the 495 kids who didn't do any of the activities frequently had new ADHD symptoms over the two-year period.

In other words, teens who were high frequency users of seven or 14 digital media platforms were more than twice as likely to develop ADHD symptoms than teens who did not use any media platform at a high frequency rate, notes Leventhal…


The article goes on to note some of the strengths and limitations of the study. The researchers urge caution in interpretation of the results; especially noting that they are talking about ADHD-like symptoms, not clinical diagnoses.

This is "preliminary" research because it presumably has not yet been replicated; and it focusses narrowly on a particular age group (10th graders) in one US county. This doesn't invalidate the findings but one must be very cautious in trying to extrapolate to all-aged adolescents everywhere. (The large subject cohort and longitudinal methodology are pluses.) It's also preliminary because it highlights the need for more research to be done in order for us to better understand how the use (and over-use) of digital media is affecting young folks, everyone else, and ultimately our culture.

I tend to agree, MADG.

Scientifically, 2,587 in one heavily-urbanized county isn't randomized enough. Heck, maybe 2 years in LA county is enough to make a 10th-grader prone to ADD; maybe excessive screen time is the symptom and not the cause.

Yeah, there it is. This doesn't mean that overuse of such media is NOT problematic; just that that this study is not conclusive
