The Internet today, beyond being a source of information and communication, has become an "addiction" for some people. The rate of Internet addiction is rapidly increasing in the world. The aim of this study was to examine the extent of Internet addiction among adolescents in North Cyprus. Eight hundred and fifty-one participants between the ages of 14 to 26 completed the Internet Use and Addiction questionnaire. Results indicated that 6.6% of the participants were addicted to the Internet. Younger high school students were found to have the highest rate of Internet addiction, followed by university students. Males were shown to have significantly higher rates of Internet addiction than females for all age groups. Academic, interpersonal and physical problems were all found to be associated with Internet addiction. The implications for guidance counsellors of this problem are discussed.
