Japanese preference weights of the Adult Social Care Outcomes Toolkit for Carers (ASCOT-Carer).

ABSTRACT:

Purpose

We developed preference weights of the Adult Social Care Outcomes Toolkit for Carers (ASCOT-Carer) in Japan.

Methods

We used best-worst scaling (BWS) and composite time trade-off (cTTO) to determine the preference weights for ASCOT-Carer states in the general population. TTO values were applied to convert the BWS scores to utilities. The sample number was approximately 1000 for the BWS survey and 200 for the TTO survey. Whereas face-to-face surveys by computer-assisted interviewing were adopted for the TTO tasks, a web-based survey was used for the BWS tasks. In the BWS tasks, the ASCOT-Carer states were presented, and the "best," "worst," "second best," and "second worst" domains in a profile were selected. A mixed logit model was applied to the BWS data.
