- The WG-SS will identify most, but not all, people with disabilities
- WG-SS questions were not designed to measure all aspects of difficulty functioning that people may experience, but rather those domains of functioning that are likely to identify a majority of people at risk of participation restrictions. These include difficulties seeing, hearing, walking or climbing stairs, remembering or concentrating, with self-care, and difficulty communicating.
- Those with psychosocial difficulties that do not impact cognition, communication or self-care will be under-reported. This issue is addressed in the extended set.
