This study, based on focus group interviews, takes a look at the physical and mental health issues related to Internet addiction and examines adolescents\' responses to Internet addiction campaigns from health communication views. In particular, grounded in culture-centered health communication perspectives, this study highlights Internet addiction as a public health issue as well as a sociocultural problem. Drawing on the understanding of the culture of adolescents, who are a part of socially marginalized groups in Korea, this study explores adolescents\' responses to the government\'s Internet addiction campaigns from their voices. According to the findings, adolescents, because of the surrounding environments and their optimistic bias, tend to pay little attention to Internet addiction campaigns while believing that the campaign messages do not evoke their sympathy and that the campaign target should be diversified.
