    abstract = "Background Among many screening tools that have been developed to detect
frailty in older adults, Clinical Frailty Scale (CFS) is a valid,
reliable and easy-to-use tool that has been translated in several
languages. The aim of this study was to develop a valid and reliable
version of the CFS to the Greek language. Methods A Greek version was
obtained by translation (English to Greek) and back translation (Greek
to English). The “known-group” construct validity of the CFS was
determined by using test for trends. Criterion concurrent validity was
assessed by evaluating the extent that CFS relates to Barthel Index,
using Pearson’s correlation coefficient. Both inter-rater and
test-retest reliability were assessed using intraclass correlation
coefficient. Results Known groups comparison supports the construct
validity of the CFS. The strong negative correlation between CFS and
Barthel Index (r(s) = - 0,725, p <= 0.001), supports the criterion
concurrent validity of the instrument. The intraclass correlation was
good for both inter-rater (0.87, 95%CI: 0.82-0.90) and test-retest
reliability (0.89: 95%CI: 0.85-0.92). Conclusion The Greek version of
the CFS is a valid and reliable instrument for the identification of
frailty in the Greek population."
