In the face of a lack of research on the game addiction process, this study sought to understand the process more deeply through the verification of the mediated effects of related variables, and it is meaningful to note the user's internal factors, unlike prior studies that focused on the game itself. In this study, we examined the mediated effects of withdrawal symptoms and loss of control in the impact of game use on game addiction among teenagers. Studies have shown that average game time per day, average game time on holidays and game duration time of teenagers causes withdrawal symptoms and loss of control, which increases the possibility of game addiction.
