According to Baidu Encyclopedia, Korean health status questionnaires are usually in Korean because South Korea is a Korean-speaking country. However, some questionnaires may provide multiple language options, including English. This will make it easier for people who do not understand Korean to participate in the survey.
There are 6 forms that Korean international students need to fill out for physical examination, including basic personal information form, health questionnaire, lifestyle habits questionnaire, family medical history form, superficial inspection form and inspection item confirmation form.
