When designing your questions, the following points can help to ensure good quality responses:
● Keep your questions simple, focused, and easy to understand. Remove unnecessary words, use non-technical language, and keep your sentences short. Be specific and avoid words that are open to interpretation; for example, use ‘daily’ or ‘weekly’ rather than ‘often’ or ‘usually’.
● Keep your survey short. We recommend a maximum of 15 questions (5 minutes for online surveys, 10 minutes for paper or phone, and 15 minutes for face-to-face).
● Avoid leading questions. These are questions that prompt or encourage a specific answer; for example, ‘How satisfied are you with the service?’
● Ask one thing at a time. For example, split ‘Did you find the session helpful and interesting?’ into two questions, because “helpful” and “interesting” are not the same thing.
● Focus on the objectives of your survey. It can be tempting to take advantage of the opportunity to gather information that is not related to your immediate objective. For example, you may want to ask about other aspects of your service, test interest in an event or project, or gauge opinion on a particular issue. This will only make your survey longer and less appealing to participants.
