Creating An Exemplary Curriculum on the Development and Standardization of The One Health Notion in Undergraduate, Graduate Education: A Delphi Study

Abstract This study aimed to develop a curriculum for offering the “One Health” course at undergraduate and graduate levels. This methodological study was conducted using the Modified Delphi Consensus Method. The study group consisted of faculty members from the Faculties of Medicine, Dentistry, Nursing, Education, Veterinary Medicine, Health Sciences, Agriculture, Science, and Economics and Administrative Sciences at Aydın Adnan Menderes University, Turkey. A total of 108 faculty members participated in the first Delphi round, while 64 participated in the second round. Data were collected via semi-structured forms distributed by e-mail and analyzed considering median, interquartile range, and standard deviation. Topics on which consensus was achieved were integrated into the stages of the Taba–Tyler Curriculum Development Model to construct a One Health curriculum. In the first Delphi round, content analysis identified five main themes: assessment and evaluation methods, teaching methods, institutional dimension, course structure and organization, and content dimension. Based on expert opinions, 66 items were generated. In the second Delphi round, these items were re-evaluated, and consensus was achieved on 50 items. Consensus criteria were defined as Median ≥ 4, IQR ≤ 1, and agreement percentage ≥ 80%, and items that did not meet these thresholds were excluded. The developed curriculum supports interdisciplinary and systems thinking and aims to promote holistic solutions to global health challenges. As a recommended framework, it may contribute to systematic integration of the One Health approach into higher education programs and serve as a reference for future One Health-based educational models, strengthening intersectoral collaboration.
