Canadian Survey on Disability (CSD)
Summary of changes
Activity on this program started: 1983
The Canadian Survey on Disability is conducted with several changes from the survey of the same name conducted in 2012.
Target population - Improvements were made to the methodology of the 2017 CSD which affect time series comparability with 2012 CSD data. Because of these important changes, it is neither possible nor recommended to compare disability data over time between the 2012 and 2017 CSD. Any comparison will be invalid. The 2016 Census, Activities of Daily Living question (found on the long form) was new, allowing better coverage of persons with a disability, especially of persons with a cognitive disability or a mental health- related disability. Therefore, coverage of persons with a disability for the 2017 CSD has improved compared to the 2012 CSD.
Instrument design - The main mode of data collection changed from a Computer-Assisted Telephone Interview (CATI) method for the 2012 CSD to an Internet-based Electronic Questionnaire (EQ) application in 2017.
Seven new modules were added in 2017. These include modules on Episodic Disabilities, General Health, use of various Health Care Services, being Housebound, Veterans of the Canadian Armed Forces, Internet Use, and Accessibility of Government Services.
Additionally, two age-related questions were added to each of the disability types. The first was to identify the onset of the
Sampling - The domains of estimation remained the same as in 2012. However, since the Activities of Daily Living question from the Census was new in 2016 compared to the questions on the 2011 National Household Survey (NHS), the approximate measure of severity used to stratify had to be modified. There were two levels of severity in 2012, and in 2017 there are three. Furthermore, stratification in 2012 took into account sub-sampling done for non-response follow-up to the NHS. This complexity is no longer required.
The minimum proportions to estimate in the computation of sample size are slightly different from 2012. They went from 9% to 10% for the 15 to 24 age group, from 7.5% to 8.5% for those aged 25 to 44 and 45 to 64 years old, from 11% to 12% for those aged 65 to 74 years old, and from 11% to 13% for the 75 years and over group. In PEI for the 15 to 44 years old group, the minimum proportion to estimate went from 9% to 8.5% while in the three territories, it went from 8% to 9% (aged 15 and over).
In 2012 the disability survey is renamed, The Canadian Survey on Disability.
In 2001 the Health and Activity Limitation Survey (HALS) was renamed the Participation and Activity Limitation Survey (PALS). The new name reflected the fact that the new survey would focus on the participation of persons with activity limitations.
The Health and Activity Limitation Survey (HALS) was first conducted in 1986.
