How do you segment patients vs. caregivers in a survey?

Definitely treat them as separate segments — their motivations and pain points are really different. I'd add a screener question upfront like 'Are you using this product for yourself or someone in your care?' and then branch them into separate question paths. Caregivers often focus on ease-of-use and reliability for *someone else*, while patients are more emotionally driven around their own health outcomes.
