Annotation	The Physical Functioning Inventory (PFI) is designed to assess changes in how and how often activities are performed by people reporting difficulty with a task as well as those who do not. This article describes the PFI, and reports on its inter-rater and test-retest reliability with active participants in the Baltimore Longitudinal Study of Aging (BLSA). Percentage agreement ranged from 63% to 100%. The PFI was also given to 392 inactive BLSA participants as part of a follow-up telephone interview. 58% of respondents reported no difficulty in performing a task, yet reported a change in how or how often they performed that task. While results indicate that the instrument is reliable and effective in detecting early stages of disability in activities of daily living (ADLs), instrumental activities of daily living (IADLs) and mobility, it is somewhat less reliable for moderate and strenuous physical activities.
