Evaluation of a global training program in One Health communication

Aim: A global Train-the-Trainer Program, focused on improving the communication techniques of One Health advocates, is assessed and evaluated in this study.

Methods: Between November 2020 and November 2022, a Train-the-Trainer Program engaged 1.583 trainees from 98 countries between the ages of 18 and 74. Trainees practiced public speaking by teaching a lesson about One Health in mostly underserved primary school classrooms. Two surveys of trainees (n = 222 and 203) assessed the impact of the Program’s orientation session on their confidence in science communication to a novice audience. The classroom teacher survey (n = 184 teachers, representing 4.109 students) measured the trainee’s impact at the community level during and following the lesson.

Results: The Program significantly improved the trainee’s confidence in communicating science (0.1 scale points) and teaching novice audiences (0.3 scale points) about One Health. Trainees cultivated student interest in One Health [median = 9 (7.3, 10)] and 90.8% of responding classroom teachers reported a desire to continue teaching about One Health after the trainee’s lesson, 99.1% noted a post-lesson increase in student interest in science, and 97.4% recommended this lesson to their colleagues.

Conclusion: This study was the first to evaluate an extensive One Health-focused communication program finding the model effective for trainees and communities alike. The trainees, through public speaking, active teaching and engaging mostly primary school students, mainstreamed One Health and inspired action in communities. The classroom teachers benefited by learning about One Health and gained a desire to share this new knowledge with others in their community.
