Leisure activities are often regarded as positive endeavors, and internet usage has become a primary leisure activity for many, especially among adolescents. However, becoming engrossed in online activities during leisure time, particularly in online gaming, is seen unfavorably. Scholarly research indicates that 13.5% of high school students in Taiwan are deeply entangled in internet addiction, which significantly im-pacts their psychological and physiological well-being. This study aims to explore the effectiveness of posters featuring low self-control and different message content in curbing internet addiction. Posters are categorized into four groups: featuring real and virtual personas, with positive and negative textual messages, along with a control group with no poster. Five scenarios were designed and distributed questionnaires were collected from 998 high school students. The analysis revealed that low self-control significantly influences internet addiction, emphasizing the necessity of enhancing students' self-control through educational means. Additionally, none of the four types of posters featuring different endorsers and textual messages effectively curbed internet addiction. This suggests that in today's information-saturated society, mitigating student internet addiction with just a poster is challenging. To address lei-sure time internet addiction, alternative approaches are needed. The study offers recommendations, suggesting strengthening restrictions on online gaming time, pro-moting diverse leisure activities and social interactions, and fostering a sense of per-sonal responsibility through education to enhance self-control.
