Custom survey links
Prefill induction and the second context field
You can share survey links that preselect the first two context fields. For Berlin Breathwork Days, use the participant link when responses should count as ordinary survey submissions:
https://alteredxproject.com/?lang=en&induction=breathwork&dose=Berlin+Breathwork+Days+2026
For collaborator testing, use the dev link. It opens the same live app with the same prefilled values, but submissions made through /dev/ are marked as test submissions and excluded from analysis:
https://alteredxproject.com/dev/?lang=en&induction=breathwork&dose=Berlin+Breathwork+Days+2026
How the link is put together
lang=en opens the English version directly. Other public language values are de and es.
induction=breathwork preselects Breathwork as the induction method.
dose=Berlin+Breathwork+Days+2026 preselects Berlin Breathwork Days 2026 in the second field.
- The
+ signs stand for spaces in the URL.
/dev/ is only for collaborator testing. Do not share it as a participant collection link.
General participant pattern:

General dev-test pattern:
https://alteredxproject.com/dev/?lang=en&induction=breathwork&dose=Your+Option+Here
For standard peer-comparison buckets, use canonical English tokens:
- Induction:
cannabis, psilocybin, alcohol, mdma
- Dose:
low, medium, high
Best practice: include induction whenever you include dose, because the available second-field options depend on the selected induction.
URL-prefill and feedback comparison are related but not identical. The questionnaire can accept options such as Breathwork and Berlin Breathwork Days 2026. The feedback comparison controls only show stable rows that are enabled in the comparison_tokens sheet tab.
