The Late-Life FDI Computer Adaptive Test (LLFDI-CAT)

latelifefunctionThe Late-Life FDI Computer Adaptive Test (LLFDI-CAT) is a patient-reported measure of ‘activity limitations’ and ‘participation restrictions’ designed for community-dwelling older adults. The LLFDI-CAT is an improved and expanded version of the original Late-Life Function & Disability Instrument (LLFDI), which is a traditional, fixed-form measure developed in 2002. The LLFDI-CAT has been designed to serve as a comprehensive, precise, and efficient measure of activity limitations and participation restrictions, which can be responsive to meaningful change in each of its two domains.

The LLDFI-CAT computer program is available free-of-charge. The manual provides support for users; however, we are not able to provide individual support for users. Boston University is not responsible for the use of the LLDFI-CAT or interpretation of LLDFI-CAT scores.
