Half of US, Japan Teens ‘Addicted’ to SmartphonesAbout half of teenagers in the United States and Japan say they are addicted to their smartphones. University of Southern California (USC) researchers asked 1,200 Japanese about their use of electronic devices. The researchers are with the Walter Annenberg School for Communications and Journalism. Their findings were compared with an earlier study on digital media use among families in North America. “Advances in digital media and mobile devices are changing the way we engage not only with the world around us, but also with the people who are the closest to us,” said Willow Bay, head of the Annenberg School. The USC report finds that 50 percent of American teenagers and 45 percent of Japanese teens feel addicted to their mobile phones. “This is a really big deal," said James Steyer, founder of Common Sense Media, an organization that helped with the study. "Just think about it, 10 years ago we didn’t even have smart phones.” Sixty-one percent of Japanese parents believe their children are addicted to the devices. That compares to 59 percent of the American parents who were asked. Also, more than 1-in-3 Japanese parents feel they have grown dependent on electronic devices, compared to about 1-in-4 American parents. Leaving your phone at home is ‘one of the worst things’ “Nowadays, one of the worst things that can happen to us is, like, 'Oh, I left my phone at home,'” said Alissa Caldwell, a student at the American School in Tokyo. She spoke at the USC Global Conference 2017, which was held in Tokyo. A majority of Japanese and American parents said their teenagers used mobile devices too much. But only 17 percent of Japanese teens agreed with that assessment. In the United States, 52 percent of teens said they are spending too much time on mobile devices. Many respond immediately to messages About 7-in-10 American teens said they felt a need to react quickly to mobile messages, compared to about half of Japanese teens. In Japan, 38 percent of parents and 48 percent of teens look at and use their devices at least once an hour. In the United States, 69 percent of parents and 78 percent of teens say they use their devices every hour. Naturally, that hourly usage stops when people are sleeping, the researchers said. The devices are a greater cause of conflict among teens and parents in the United States than in Japan. One-in-3 U.S. families reported having an argument every day about mobile device use. Only about 1-in-6 Japanese families say they fight every day over mobile devices. Care more about devices than your children? But 20 percent of Japanese teens said they sometimes feel that their parents think their mobile device is more important than they are. The percentage of U.S. teens saying they feel this way is 6 percent. In the United States, 15 percent of parents say their teens’ use of mobile devices worsens the family’s personal relationships. Eleven percent of teens feel their parents’ use of mobile devices is not good for their relationship. The USC research was based on an April 2017 study of 600 Japanese parents and 600 Japanese teenagers. Opinions from American parents and teenagers were collected in a study done earlier by Common Sense Media. Bay, the Annenberg School of Communications dean, said the research raises critical questions about the effect of digital devices on family life. She said the cultural effects may differ from country to country, but “this is clearly a global issue.”
