Answer: For people who are 57 to 59 years old, there will not be much error in using the older adult forms and their norms. At ages much above 90, the norms become less relevant for the following reasons: (a)The normative samples did not include many people older than 90; and (b) above the age of 90, most people’s functioning is apt to be increasingly affected by physical limitations. However, the raw item and scale scores continue to provide helpful information about people’s adaptive strengths and problems. Furthermore, stability, and change in people’s functioning can be evaluated by having the OASR and/or OABCL completed at convenient intervals, even if the norms are less relevant than at younger ages
