Validation of the Late-Life Function and Disability Instrument in People Living with COPD.

ABSTRACT:

Background

Disability and loss of function are acknowledged as important problems for people living with COPD, but there is a need for validated tools to assess them.

Research question

The Late-Life Function and Disability Instrument (LLFDI) was originally validated for community-dwelling older adults. The full instrument has not been validated to assess disability and loss of function in people with COPD.

Methods

People with COPD from 6 European countries completed the LLFDI as part of an observational study. Its validity was assessed in terms of 1) levels and distribution of LLFDI domain and subdomain scores; 2) floor and ceiling effects; 3) instrument structure (3 domains, 7 subdomains) by confirmatory factor analysis; and 4) construct validity by (i) convergent va
