Tests, after-school activities and problems at home can increase stress for students. But research now suggests that the main reason for the students’ rising anxiety levels is something else.
A psychology professor Jean Twenge said “What a lot of teens told me is that using social media and their phones seems forced. This use of phones has led to a loss of sleep and face-to- face interactions.” Last year, in the journal Pediatrics three researchers wrote that too much social media use might contribute to the development of mental health problems in teenagers, such as loneliness, depressive symptoms and anxiety.
Researchers are still not sure whether phones cause student depression or depression causes phone use. Yet 70 percent of teens see anxiety and depression as major problems among their peers, according to a February Pew Research Center report.
Schools are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of pain. Some schools have organized some events in which people do not use their electronic devices. Belfast Area High School in Maine had one such event in April. About 20 percent of students and school employees took part, demonstrating the influence that the technology has on their daily life.
Emily Mogavero, a 17-year-old student in New York, said “I definitely feel stressed to keep up my information and stuff. It kind of worries me that I’m on my smart phone so long.” Mogavero said she sometimes puts her phone out of reach or powers it down so she doesn’t hear anything.
Some parents are not letting their children get smart phones until they grow up. A teacher, Erin Schifferli, says her 12-year-old daughter, Aeva, won’t get a phone until she is 16 years old. Deirdre Birmingham of Montclair signed on a campaign called “Wait Until Eighteen” because she didn’t think her video game-loving 10-year-old son was ready for a smart phone.
