Internet addiction is a controversial phenomenon although it is clear that some children (and adults) spend too much time online at the expense of their school or work performance, family relationships and emotional state. Researchers from Kaohsiung Medical University in Taiwan looked into the links between ADHD (Attention Deficit Hyperactivity Disorder), social phobia, hostility and Internet addiction in 2,293 year 7 students. They found that 10.8% of the participants coud be classified as having an Internet addiction. Depression, ADHD, social phobia and hostility were all found to predict Internet addiction when the children were followed up again two years later. However, depression and social phobia predicted Internet addiction only among girls. The most significant predictor of Internet addiction among boys was hostility, among girls the most significant predictor was ADHD.
