Abstract:

International comparison of functional health and disability is often hampered by important differences in key aspects such as survey instrument, data collection methods, etc. The Joint Canada/U.S. Survey of Health (JCUSH) represents the first time the same survey is conducted to measure the health of both Canadian and U.S. citizens, using standardized methodology. This paper compares disability and functional limitation in both countries, based on four different modules, namely, U.S. questions on vocational restriction of activities and on limitation of activities as well as Canadian questions on restriction of activity and those for the construction of the Canadian Health Utilities Index (HUI). These measures are clearly related to one another, but they produce different estimates of the levels and distribution of health status in populations. We will compare the age-adjusted prevalence rates of disability/functional limitation derived by the four modules, and explore whether they produce consistent differentials. These are important first steps in the discussion as to whether and how the questionnaires across countries can be brought closer in disability measurement.
