Mapping the Washington Group on Disability Statistics disability measure to the Health Utilities Index Mark 3: Development and validation of a predictive multivariable model in a general population sample
Articles and reports: 82-003-X202500100001Description: Statistics Canada collects information on functional health and related concepts. Recently, the Washington Group on Disability Statistics (WG) measure of disability has been 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. Since the WG measure is not preference-based, it is unable to derive these measures. To address resulting data gaps, this study provides the conclusions of a mapping process whereby the utility scores of the HUI3 were estimated from the WG disability measure. Following selection of preferred models, this study provides prediction equations used to estimate the HUI3 score and validates the results of the mapping process.
