Mapping the Washington Group on Disability Statistics Disability Measure to the Health Utilities Index Mark 3: Development and Testing of Qualitative and Predictive Multivariable Models in a General Population Sample

Articles and reports: 11-633-X2025001
Description: Statistics Canada routinely collects information on functional health and related concepts. Recently, the Washington Group (WG) measure of disability was introduced to the Canadian Community Health Survey (CCHS). The WG measure is used as a tool for developing internationally comparable data on disability. In alternate cycles of the CCHS, it replaces the Health Utilities Index Mark 3 (HUI3), a generic preference-based measure of health-related quality of life, used to derive evaluative health measures common in population health and economic evaluations. To address resulting data gaps, this study provides an overview of the mapping process whereby the utility scores of the HUI3 were estimated from the WG disability measure. This detailed overview of instrument mapping includes qualitative approaches in addition to mapping through statistical estimation.
