In our study, another predictor of Internet addiction was found as social self-esteem. Given the importance of social relationships during adolescence, it seems inevitable that the self-esteem levels of adolescents affected by the qualities of peer relationships. Craig (1995) states that, an individual’s negative self-evaluation in peer relationships may cause the dependent behaviors in order to avoid these stressful relationships (As cited in Armstrong at al., 2000). Padwa and Cunningham (2010) refer to social factors associated with Internet addiction. According to them, online games with multi-player attract young people because these games are simulation of social communication in real life. In addition, a degree of anonymity especially attracts individuals who may be anxious in social situations. In relevant literature, it is not reached a consensus whether self-esteem is a cause or a result of Internet addiction (Niemz at al., 2005; Shaw & Gant, 2002). In this study, self-esteem is discussed as an antecedent to Internet addiction. As mentioned above, self-esteem is an important determinant of individuals’ behaviors and activities. Some of these activities support development of an individual; on the other hand some of them are harmful for personal development. Internet addiction is one of them and with a sense of diminishing self-control, it may cause a further reduction in self-esteem. The general inference we can make is that self-esteem has an influential role on adolescents’ development. Thus, adolescents need to gain the belief that they are worthy. An emphatic understanding of their experiences and accepting them as they are may be the first step taken by parents, educators and counselors. Within the school environment, presenting a large number of social and sporting opportunities for adolescents to test and develop their abilities may also be very helpful. As a final recommendation, it is thought that counselors should organize informative and preventive group activities about the proper use of Internet and the results of excessive use. In this study certain limits should be considered. The data are not representative of adolescents throughout Turkey because this study conducted only in Trabzon. Secondly, all of the data collected in this study were obtained from self-report scales. Therefore, the results may be limited by the adolescents’ lack of openness. In conclusion, this study is an effort to examine whether self-esteem is determinant on Internet addiction. Based on the results of this study, experimental studies aimed at promoting self-esteem on adolescent addicts would be done.
