Teens who use the Internet excessively appear to be more likely to develop depression, according to a study set to appear in the October 2010 issue of Archives of Pediatrics and Adolescent Medicine.
Lawrence T. Lam, of the School of Medicine, Sydney, and the University of Notre Dame, Fremantle, Australia and Zi-Wen Peng, of the Ministry of Education and Sun Yat-Sen University, Guangzhou, China studied the relationship between pathological Internet use (defined as uncontrolled or unreasonable levels of usage) and later mental health issues among 1,041 Chinese teens with an average age of 15.
At the beginning of the study, 62 teens (6.2%) were classified as having moderately pathological use of the Internet (based upon a survey designed to identify pathological usage patterns), while 2 (0.2%) were at severe risk. After nine months, the teens were assessed for anxiety and depression. Eight (0.2%) had significant anxiety while 87 (8.4%) had developed depression. Those who had been identified as having pathological Internet use were at about two and half times more risk of having developed depression than those who had not exhibited pathological use. No relationship was observed between pathological Internet use and anxiety, however.
"This result suggests that young people who are initially free of mental health problems but use the Internet pathologically could develop depression as a consequence," said the authors. They further suggest that "a screening program for pathological use of the Internet could...be considered in all high schools to identify individuals at risk for counseling and treatment."
