Briefly Noted

Researchers have found that attention‐deficit hyperactivity disorder (ADHD) may be a risk factor for developing smartphone addiction, based on the neurobiological substrates underlying each separately and those that are shared. The study found a greater than six times likelihood that children with ADHD also had smartphone addiction. The study looked at the prevalence of smartphone addiction and its association with depression, anxiety, and ADHD symptoms in a total of 4,512 South Korean middle and high school students, who completed surveys. There were 338 subjects (7.5%) in the smartphone addiction group. The odds ratio of the ADHD group compared to the non‐ADHD group for smartphone addiction was 6.43, the highest among all variables. The study, “The relationship between smartphone addiction and symptoms of depression, anxiety, and attention‐deficit/hyperactivity in South Korean adolescents” is published in the March issue of the Annals of General Psychiatry.
