A questionnaire is an instrument usually used in survey research. How to make a good questionnaire so that it can provide us the best results (valid, reliable) to our study?
Simple steps:
1. Literature review
2. Key informant interviews/ focus groups
3. Make a questionnaire
4. Get reviews from experts and sample audience (face and content validity)
5. Refine
6. Send for stability reliability analysis.
7. Use statistical techniques to assess instrument properties (validity and reliability).
Good luck!
