There have been several topics getting special attention regarding mental health issues recently: prevalence of suicide, depressions, violent behaviors, addictions, etc. Among those, addiction has been very popular to diverse groups of people in the society causing many negative consequences. From smoking addiction and alcohol addiction to the addiction to abnormal sexual activities are common issues in general among adult groups. On the other hand, addiction to online-games has been one of the most popular issues for young people including teenagers. Diverse organizations have made many efforts in order to improve this situation and to prevent serious addiction among many teenagers. Based upon this atmosphere, some legislators suggested making a special law limiting teenagers’ usage of online-games. This exploratory study is about how we can make more effective messages exposed to teenagers encouraging them to think about the seriousness of online game addiction when they are actually playing online-games. The researchers conducted an experiment testing the effects of different types of messages promoting adequate playing of online-games which they are exposed to inside the online game interface. The results found that two independent variables applied in this study (physical-psychological appeals, Positive-negative framing) significantly influence teenagers’ attitude toward the messages and their intention to limit their time to play online-games in the future. The results from this study could provide important insights for crafting better and effective messages and other PR tools encouraging teenagers to reduce their time spending on playing online-games.
