Participant studies
Design pre- and post-interaction questionnaires
Measure baseline beliefs and later outcomes without losing the transcript or confusing participants at the transition.
The basic idea
Pre/post measurement estimates change more directly than a post-only score, but asking a question before treatment can itself influence later responses. Choose timing deliberately, keep wording stable when measuring change, and preserve the interaction before moving to the questionnaire.
Ask policy support and confidence before the AI interaction, preserve the full discussion, display an explicit transition, then repeat the outcomes and add treatment-experience questions.
How to do it
- 1
Define which outcomes are measured before, after, or at both times.
- 2
Use identical wording and scales for paired pre/post outcomes unless a planned reason requires a change.
- 3
Mark sensitive or nonessential items optional and order questions from essential outcomes to secondary measures.
- 4
Preview the transition and both questionnaire stages as a participant before launch.
What to watch for
- Pretesting can prime the topic or treatment mechanism.
- Changing labels or scale direction between waves can create artificial change.
- Do not require sensitive questions unless the study genuinely needs them and consent covers them.
What a useful result looks like
The dataset contains clearly timed, analyzable responses tied to the same participant and interaction while the user sees an understandable progression through the study.
