The overall design of the questionnaire is poor, and the question expression is inappropriate, which leads to the decline of the reliability and validity of the questionnaire. Once a hot event, problem or situation is selected for scientific and in-depth investigation and study, the questionnaire must be strictly designed first. Because the investigators are impetuous, eager for success and thoughtless about details, there are some problems in the questionnaire design, such as sampling error, poor structure, improper ranking, compound problems, inaccurate statements or suggestive statements.
Privacy related and sensitive issues, etc. , can affect the respondents' real thoughts, make them suspicious and unwilling to cooperate with the answer. In the process of investigation, there is a lack of necessary explanation for the respondents and the explanation of the questionnaire is ignored.
