The increasing risk of zoonotic spillover, driven by climate change and evolving human behaviors, requires a systematic shift in pandemic prevention strategies towards a One Health approach. Central to this approach is effective health communication intended to translate knowledge into actionable recommendations for the most vulnerable populations. This thesis aims to systematically evaluate the quantity and quality of existing One Health communication materials through a scoping review and two distinct methods of quality evaluation: the CDC Clear Communication Index and content analysis. Among 82 communication materials identified in the scoping review, the median overall CDC Clear Communication Index score was well below 90%, indicating that most materials did not meet high-quality standards. Furthermore, the content analysis revealed disparities in the frequency of concepts across all materials and among the target audience. Notably, specific concepts were most prevalent in high-scoring CDC Clear Communication Index materials including behavior and skill-focused COM-B targets, risk communication, health promotion, disease prevention, animal handling, and general health literacy. These reoccurring themes underscore the significance of crafting One Health communication material that integrates several concepts and intentional designs to maximize effectiveness. This research offers practical recommendations for the future direction of effective health communication, fostering more resilient and informed communities through a collaboration One Health approach.
