Randomised comparison of online interviews versus face-to-face interviews to value health states.

ABSTRACT:

Introduction

Health state valuation studies using composite time trade-off (cTTO) interviews have historically been conducted face-to-face. The COVID-19 pandemic forced disruptive innovation meaning a number of valuation studies conducted interviews via videoconference. These studies found online interviews feasible and acceptable; however, studies were not constructed to test the impact of online versus face-to-face interviews. This study builds on its sister study from the UK and aims to assess the acceptability and equivalence of in person face-to-face interviews with online interviews on cTTO valuation outcomes and on data quality.

Methods

Participants were recruited into a randomised equivalence study via an external research company. Consenting participants were random
