Abstract
Introduction
The Late Life Function and Disability Instrument (LLFDI) is a valid self-report tool that quantifies disability based on activity limitations and participation restrictions in everyday life. Both the original longer tool (LLFDI) and the shorter computer adaptive version (LLFDI-CAT) offer practitioners a method for measuring function independent or in conjunction with performance-based assessment. Objectives: Examine scores of the LLFDI and LLFDI-CAT for measuring disability in older adults who are receiving rehabilitation services in community and institution settings. Method: A secondary data analysis was conducted comparing scores from occupational therapy evaluations with older adults from 3 groups: 1) older adults in primary care using the LLFDI; 2) older adults in primary care using the LLFDI-CAT; older adults in a skilled nursing facility (SNF) using the LLFDI-CAT.
Results
Mean scores for Activity Limitation and Participation Restriction were lowest for older adults in a SNF indicating greater disability. A one-way Analysis of variance on ranks showed a main effect for Activity Limitation, χ2 (2) = 22.267, p < 0.001, and Participation Restriction, χ2 (2) = 60.372, p < 0.001. Post-hoc analyses revealed significant differences between groups based on tool (i.e. LLFDI vs. LLFDI-CAT) for Activity Limitations and setting (i.e. primary care vs. SNF) for Participation Restriction.
Conclusion
The LLFDI-CAT may be the preferred instrument to measure disability in older adults across treatment settings. Additional research is warranted to understand how personal and environmental factors influence LLFDI-CAT outcomes.
