In order to conduct online clinical practice under the COVID-19 pandemic, we attempted to introduce behavioral medicine education in obstetrics and gynecology clinical practice. Forty fifth-year medical students were given Case Based Learning using scenarios in a two-week rotational clinical practice. The scenarios were obstetrics and gynecology cases based on the themes from the “Behavioral Medicine” textbook. The curriculum consisted of discussions during practical training using Zoom and independent study outside of the training time. After the practical training, we received comments from students suggesting there was a change in their awareness, such as “Behavioral medicine was previously classroom knowledge, but now I am able to be aware of it in subsequent practical training.”
