Participation and Activity Limitation Survey (PALS)

Summary of changes

Activity on this program started: 1983

Reference period of change - 2017

Target population - The 2016 Census long form Activities of Daily Living questions are new, and will allow better coverage of persons with a disability, namely of persons with a cognitive disability or a mental-health related disability. Coverage of persons with a disability for the 2017 survey will therefore be improved compared to the 2012 survey.

Instrument design - The main mode of collection transferred to an Electronic Questionnaire (EQ).

Five new modules were added. These include a module on General Health, being Housebound, Veterans, Internet Use, and Accessibility of Government Services.

Additionally two age-related questions were added to each of the disability types. The first is to identify the onset of the disability and the second to indicate when the disability started to effect daily activities.

Sampling - The domains of estimation remained the same as in 2012. However since the Activities of Daily Living questions from the long form Census were new in 2016 compared to the ones on the National Household Survey in 2011, the approximate measure of severity used to stratify had to be modified. There were 2 levels of severity in 2012, now there are 3. 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 years old, from 7.5% to 8.5% for the 25 to 44 and 45 to 64 years old, from 11% to 12% for the 65 to 74 years old, and from 11% to 13% for the 75 years and over. In PEI for the 15 to 44 years old, the minimum proportion to estimate went from 9% to 8.5% while in the three territories, it went from 8% to 9%.

No additional sample was drawn in 2012.
