Enhancing Pre-Travel Health Communication for International Travelers Through Visual and Text Synergy

International travelers are particularly vulnerable due to their unfamiliarity with local environments and limited access to timely health information about emerging risks at their destinations. Effective health communication can significantly improve travelers' decision-making abilities to reduce health risks. Understanding and supporting travelers' health communication process-specifically their behaviors around seeking, processing, and applying pre-travel health advice-becomes crucial for mitigating health risks and strengthening health communication efforts. This study employs a multimethod approach, incorporating the biometrics of eye-tracking technology and cross-sectional surveys to examine the synergy between visual and textual elements in pre-travel health communication. The finding provides evidence that travelers' efficacy beliefs significantly motivate them to adopt self-protective actions. Furthermore, the study highlights the pivotal role of self-efficacy and dual-coding strategies in enhancing traveler's recall of health and safety messages.
