Impacts of the preceding cancer-specific health-related quality of life instruments on the responses to the subsequent EQ-5D-5L.

ABSTRACT:

Background

In clinical studies, the EQ-5D-5L is often employed with disease-specific health-related quality of life instruments. The questions in the former are more general than the latter; however, it is known that responses to general questions can be influenced by preceding specific questions. Thus, the responses to the EQ-5D-5L have the possibility of being influenced by the preceding disease-specific health-related quality of life instruments. This may lead to bias in the cost-effectiveness analysis results. Therefore, this study aimed to evaluate the impact of the preceding cancer-specific health-related quality of life instruments on the EQ-5D-5L responses.

Methods

We prepared questionnaire booklets containing the EQ-5D-5L, the European Organization for Research and
