動物における抗生物質使用に関する獣医師の態度、知識、実践：質問票のデザインと信頼性

Antimicrobial resistance (AMR) is a global public health concern that requires a One Health approach. The role of veterinarians in promoting antimicrobial stewardship is essential for successful mitigation of AMR.

This study aimed to design a self-administered questionnaire and evaluate its reliability as a tool to assess veterinarians' knowledge, perceptions, and attitudes regarding AMR and antibiotic prescription and use in animals.

The questionnaire was developed based on a comprehensive review of relevant literature and by employing collective intelligence methodologies, including focus groups with veterinarians and pharmacists. For the pilot study, veterinarians working in the Northern region of Portugal were recruited. A test-retest was conducted with a 4-week interval. Reproducibility was determined with the intraclass correlation coefficient (ICC; 95% confidence interval) and internal consistency was calculated using Cronbach's alpha.

In total, 31 (out of 34) veterinarians completed the retest phase of the study. Four sections with scale-items were assessed for reliability, with ICC values ranging from 0.10 (p = 0.285) in Section 2 (AMR) to 0.85 (p < 0.001) in Section 4 (prescription and antibiotic use). The questionnaire achieved Cronbach's alpha coefficient values of 0.81 and 0.78 in test and retest, respectively. Based on ICC values and veterinarians' comments, some items were deleted or reformulated.

The developed questionnaire is a reliable instrument capable of capturing veterinarians' knowledge, perceptions, and attitudes on AMR and antibiotic use.
