Late-Life Function & Disability Instrument™

Late-Life FDI

The Late-Life FDI™ is an outcome instrument developed specifically for community-dwelling older adults. The Late-Life FDI™ assesses and responds to meaningful change in two distinct outcomes: function–a person’s ability to do discrete actions or activities, and disability–a person’s performance of socially defined life tasks. There is a 16-item disability component and a 32-item function component.

Application

The Late-Life FDI™ is used to assess clinical outcomes in programs designed for elderly individuals. It is also used in clinical research studies to examine the impact of treatment and pharmacological interventions that aim to improve function and minimize disability.
