Washington: People who use the Internet more randomly, switching between applications may be showing signs of depression, a new study led by an Indian-origin researcher has claimed. Analysing Internet usage among college students, a team led by Sriram Chellappan at Missouri University of Science and Technology found that those who show signs of depression tend to browse differently than others. The researchers identified nine fine-grained patterns of Internet usage that may indicate depression. For example, students showing signs of depression tend to use file-sharing services more than their counterparts, and also use the Internet in a more random manner, frequently switching among several applications. They also tend to send email and chat online more than the other students, LiveScience reported. Depressed students also tended to use higher "packets per flow" applications, those high-bandwidth applications often associated with online videos and games, than their peers, the researchers said. "The study is believed to be the first that uses actual Internet data, collected unobtrusively and anonymously, to associate Internet usage with signs of depression," Chellappan said in a statement.
