Enhancing public response to meteorological disaster warnings: A perspective from the IDEA model

This article examines how the content and format of meteorological disaster warnings affect public risk perception and protective action. Using the IDEA model (internalization, distribution, explanation and action), the study tests different warning messages through a quasi-experimental questionnaire design. It focuses on how textual, image-based and video-based warnings influence people’s understanding of risk and their willingness to take preparedness measures.

This study validated and extended the applicability and theoretical foundations of the IDEA model in non-textual contexts, offering insights for the advancement of disaster warning theory. The key takeaway is that warning messages need to be not only timely and credible, but also personally relevant and action-oriented. The study finds that text warnings are more effective when they include internalization and action elements, while visual formats do not automatically improve public response. The article highlights the importance of designing early warning communication around clear guidance, audience needs and practical protective behavior.
