Considerations

This assessment can be used to define a client's level of function that can be easily understood across professionals and disciplines. This assessment only measures basic ADLs and does not provide any information regarding higher level ADLs and IADLs, this also causes a ceiling effect. There is also some debate over the hierarchy of ADLs proposed by Katz, as well as the inability of the scale to capture a client’s need for little assistance versus substantial assistance.
