The misuse and overuse of antibiotics represent a critical global issue and one of the most pressing public health challenges of the 21st century. Training future healthcare professionals effectively is essential for ensuring responsible antibiotic use. This study aimed to validate a questionnaire designed to evaluate the knowledge, attitudes, and perceptions of medical students regarding the education they receive on infectious diseases, antimicrobial resistance, and antibiotic stewardship during their university studies. : A self-administered questionnaire was developed and distributed to medical students at the University of Santiago de Compostela. Comprising 44 items, the questionnaire assessed eight key dimensions: "infection diagnosis", "criteria for not prescribing antibiotics", "initial antibiotic therapy", "re-evaluation of therapy", "quality of care", "communication skills", "antibiotic resistance", and "teaching methodology". Validation was carried out in two stages: Phase 1 involved content and face validity, while Phase 2 focused on reliability analysis. : A total of 295 students completed the questionnaire, with a mean age of 23.15 ± 1.78 years. The sample included 86 male (29.2%) and 209 female (70.8%) respondents. Content and face validity were established by a nominal group of five experts and a focus group of medicine and pharmacy students to ensure consensus on item understanding in the Spanish language. The questionnaire demonstrated high internal consistency with a Cronbach's alpha of 0.92 and satisfactory item discrimination. Construct validity was confirmed through principal component analysis, which supported the presence of the eight predefined dimensions. : The validated questionnaire exhibited strong reliability and validity, making it a valuable tool for assessing medical students' training in antibiotic-related topics. Its application will enable the identification of areas for improvement in university curricula, ultimately contributing to the promotion of appropriate antibiotic use and the reduction of antimicrobial resistance.
抗生素的滥用和过度使用是一个严峻的全球问题，也是21世纪最紧迫的公共卫生挑战之一。有效培训未来的医疗保健专业人员对于确保抗生素的合理使用至关重要。本研究旨在验证一份问卷，该问卷旨在评估医学生在大学学习期间接受的关于传染病、抗菌药物耐药性和抗生素管理教育的知识、态度和认知。：设计并向圣地亚哥德孔波斯特拉大学的医学生发放了一份自填式问卷。该问卷包含44个项目，评估了八个关键维度：“感染诊断”、“不使用抗生素的标准”、“初始抗生素治疗”、“治疗重新评估”、“护理质量”、“沟通技巧”、“抗生素耐药性”和“教学方法”。验证分两个阶段进行：第一阶段涉及内容和表面效度，而第二阶段侧重于可靠性分析。：共有295名学生完成了问卷，平均年龄为23.15±1.78岁。样本包括86名男性（29.2%）和209名女性（70.8%）受访者。由五名专家组成的名义小组以及医学和药学专业学生组成的焦点小组确定了内容和表面效度，以确保在西班牙语中对项目理解达成共识。该问卷显示出较高的内部一致性，克朗巴哈系数为0.92，项目区分度令人满意。通过主成分分析确认了结构效度，该分析支持了八个预定义维度的存在。：经过验证的问卷具有很强的可靠性和有效性，使其成为评估医学生抗生素相关主题培训的宝贵工具。其应用将有助于确定大学课程中需要改进的领域，最终有助于促进抗生素的合理使用并减少抗菌药物耐药性。
