At a time when COVID-19 infections are continually occur and it will take time for collective immunity to COVID-19 to be realized, it is best for individuals to continue to follow precautions to prevent COVID-19. Based on the health belief model (perceived susceptibility, severity, benefit, barrier and self-efficacy), this study added negative feelings about COVID-19, media and interpersonal information exposure, interdependent self-construal to the health belief model and tested suggested model. The data of this study were collected through survey company using quota sampling by gender, age and residence. The study sample consisted of 299. As a result of the study, it was found that perceived severity, perceived barrier, and self-efficacy had a significant effect on the intention to continue COVID-19 prevention behavior as suggested by the health belief model. Negative emotions toward COVID-19 were found to have a positive effect on the intention to continue COVID-19 prevention behavior. As a result of examining the influence of media and interpersonal information exposure, it was found that only interpersonal information exposure had a significant effect. Specifically, it was found that the more conversations about COVID-19 with acquaintances and family members, the higher the perceived severity of COVID-19, negative feelings about COVID-19, and the higher the intention to continue preventive actions. In addition, it was found that the exposure of personal information of COVID-19 directly affects the intention to continue preventive behavior, and indirectly affects the intention to continue preventive behavior through perceived severity and negative emotions. Interdependent self-construal was found to have a positive effect on perceived severity and negative emotions. Perceived severity and negative emotions influenced the intention to continue COVID-19 prevention behavior, indicating that these two factors mediated between interdependent self-construal and the intention to continue the prevention behavior. This study is theoretically meaningful in that it expanded the health belief model and applied it to a new infectious disease called COVID-19 and laying the foundation for subsequent research and development on infectious disease prevention behavior. In practical terms, it is meaningful that the study results can help develop and devise campaigns for COVID-19 prevention and also provide practical information on the development of health communication messages and quarantine policies for the emergence of new infectious diseases. Based on the research results, the limitations of the study and the direction of future studies were presented.
