PURPOSE: To translate and perform a cross-cultural adaptation of the Late-Life
Function and Disability Instrument (LLFDI) to Swedish, to investigate absolute
and relative reliability, concurrent validity, and floor and ceiling effects
within a Swedish-speaking sample of community-dwelling older adults with
self-reported balance deficits and fear of falling. METHOD: Translation,
reliability and validation study of the LLFDI. Sixty-two community-dwelling,
healthy older adults (54 women and 8 men) aged 68-88 years with balance deficits
and fear of falling performed the LLFDI twice with an interval of 2 weeks.
RESULTS: Test-retest agreement, intra-class correlation coefficient was very
good, 0.87-0.91 in the LLFDI function component and 0.82-0.91 in the LLFDI
disability component. The standard error of measure was small, 5-9%, and the
smallest real difference was 14-24%. Internal consistency (Cronbach's alpha) was
high (0.90-0.96). Correlation with the SF-36 PCS and PF-10 was moderate in both
LLFDI function, r = 0.39-0.68 and r = 0.35-0.52, and LLFDI disability, r =
0.40-0.63 and 0.34-0.57, respectively. There was no floor or ceiling effects.
CONCLUSION: The Swedish version of the LLFDI is a highly reliable and valid
instrument for assessing function and disability in community-dwelling older
women with self-reported balance deficits and fear of falling. Implications for
Rehabilitation The Swedish LLFDI is a highly reliable and valid instrument for
assessing function and disability in older women with self-reported balance
deficits and fear of falling. The instrument may be used both in clinical
settings and in research. The instrument is sensitive to change and a reasonably
small improvement is enough to detect changes in a group or a single individual.
