# Research eligibility question survey

Improve clarity of a study's participation criteria.

If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

## 1. Which experience does the question ask about?

Answer: ____________________

## 2. What time frame was unclear?

Answer: ____________________

## 3. What option would fit your situation?

Answer: ____________________

## Author notes / illustrative keys where applicable

1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: participants cannot distinguish recent from past product use.
2. An unclear timeframe exposes ambiguity in whether an experience qualifies someone for the study. State the actual reference period and criteria, without treating an understandable screener as proof of representative recruitment.
3. Identify the answer choice needed to describe the participant’s relevant experience accurately, including none or uncertainty. Review choice coverage against the actual criteria without collecting unnecessary personal details.

Interpretation caution: Do not collect unnecessary personal screening details.


## Illustrative finding and follow-up

Observation: Participants cannot distinguish recent from past product use.

Action to test: State the relevant experience window.

Follow-up: After trying the change, repeat “Which experience does the question ask about?” with people who experienced it. Check whether they still describe the original issue: participants cannot distinguish recent from past product use. Compare explanations and sample context, rather than claiming the change caused an improvement.
