Participants who actually finish.
A questionnaire study lives or dies on the last page. COHORT is the platform we built after watching too many good instruments lose half their respondents somewhere around question forty — adaptive routing, honest progress, reminders that know when to stop, and per-item analytics that tell you exactly where people leave.
People who abandon a questionnaire still care about your research. They leave because question thirty-one asked something question fourteen already answered.
Every commercial survey tool measures whether a response was submitted. Almost none measure which item lost the person, on which device and in which minute, and without that number you cannot fix anything.
COHORT instruments the questionnaire the way a serious product team instruments a checkout. Then we change the items the data indicts, and run the wave again.
It plugs into what you already have: REDCap can stay your database, with COHORT as the front door.
Ten thousand invitations. Where do they go?
From instrument to fieldwork.
Instrument review
Your questionnaire, item by item: what it measures, what it duplicates, and what it will cost you in completions.
