Questionnaires and discussion guides:

• should be balanced and objective
• provide an environment where the respondent is free to state their opinion
• accommodate respondent level of understanding or knowledge
• provide clarity on what is expected
• can explore hypothetical responses to stimulus

Questions must:

• be limited to the subject of the market research study
• not be promotional in any way
• not request or encourage any change in behaviour or attitude
• not be misleading or leading in nature

Screeners should be used purely for recruitment purposes and not data collection

You must also limit the collection of personal data to only that which is necessary for the purposes of the work.
