Generally, if it is a questionnaire containing a scale, it is necessary to analyze the reliability and validity. No-metric questionnaire can be described in written form, no matter what kind of questionnaire, it should be described in the paper to prove the reliable data quality.

If it is a self-made scale, it is generally necessary to pre-test, that is, distribute the questionnaire in a small range, analyze the reliability and validity, and modify or delete the items with low reliability and validity, so that researchers can make some adjustments to the initial questionnaire and form the final version. Of course, formal research still needs to do reliability and validity analysis.

For a detailed analysis of reliability and validity, please refer to the help manual of SPSSAU.
