How well do participants understand the questions asked in the Online Personal Utility Functions (OPUF) approach? A cognitive debrief of the EQ-HWB-S (EQ Health and Wellbeing Short version) valuation.

Purpose

Online elicitation of Personal Utility Functions (OPUF) is an innovative approach to valuing health states.

Coding drew upon a Framework approach, with final codes including an assessment of how participants engaged with each of the five OPUF tasks based on whether (1) they completed as expected, (2) minor concerns were id
