Electroconvulsive therapy (ECT) is a safe and effective treatment option for various psychiatric disorders. However, its widespread use is limited by prevalent negative attitudes and stigma, not only within the general public but also among healthcare professionals. This study aimed to develop and validate a workshop-based educational module, titled the "Basic Course in ECT," for medical students. The curriculum development framework was used to develop the educational module. The content of the educational module was developed through expert consensus involving two rounds of the Delphi method. Faculty members provided feedback to validate the workshop content. A total 33 interns participated in the workshop. Student satisfaction was assessed using a feedback questionnaire. Eight content areas were identified through a literature review. The Delphi consensus with 15 experts resulted in 10 topics being incorporated into the educational module. The module demonstrated strong face validity, as indicated by a content validity index of 1. Participants expressed high satisfaction with the workshop module regarding content, teaching methods, and time allocation. Feedback indicated an improvement in knowledge and a positive attitude toward ECT. The "Basic Course in ECT" was developed using expert consensus and validated for use with medical students. It can be integrated into the undergraduate curriculum.
