1. Title. Following the principle of "clarity+conciseness", sensitive topics sometimes need to be blurred or neutralized to avoid implied meaning.

2. introduction The design of the lead is related to the first impression of the questioner. It is usually necessary to indicate the identity of the investigator, the abstract purpose of the investigation, the purpose of the study, the filling instructions of the questionnaire, and the matters needing attention.

3. Basic information. Generally, it is relatively stable personal static data such as gender, age, education, occupation/specialty. If these variables are not involved in the study, this part can be omitted.

4. Main contents. It is the core of the questionnaire, and the questions should be set according to the research purpose and close to the theme. Don't ask too many complicated questions, otherwise it will easily arouse the disgust of the filler. The questioner's time and patience are limited, so the capacity of the questionnaire is also limited. Each question should closely focus on the purpose of the survey, and the ideal questionnaire design is to control the time for respondents to answer questions to about 5 minutes.

The purpose of the study is abstract and macroscopic, and the design of the questionnaire should decompose the purpose of the study to the microscopic level through specific questions. When designing questions creatively, we should not only consider the theoretical significance, but also consider the understanding of the respondents. Try to turn abstract concepts into observable quantitative concrete indicators.

5. Conclusion. Express sincere thanks to the respondents.
