Screener surveys

A screening survey contains a list of qualifying questions that can be administered to people online or offline. Often, people being screened may find ways to answer favorably to participate in the study.

To avoid influencing participants' answers:

• Ensure your survey contains open-ended questions. This encourages people to think on their own and avoid guessing what’s “right.”
• When using multiple choice questions in your screener survey, ensure you include distractors in the options. They closely resemble the correct answer but are, in fact, wrong. This helps you identify people who guess or pick favorable answers.
• Avoid sharing too many details about your study during the screening stage as this too can influence people to answer a certain way.^[1]
