A Head-On Ordinal Comparison of the Composite Time Trade-Off and the Better-Than-Dead Method

ObjectivesThe valuation of health states worse than dead is challenging. Currently used time trade-off methods face problems in (1) detecting time-dependent preferences and (2) insensitivity toward severity for states worse than dead. The better-than-dead (BTD) method has the potential to detect time-dependent preferences. This study compares the BTD and composite time trade-off (cTTO) methods at the ordinal level.MethodsAn experiment was...
