Abstract
BackgroundAmong 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.MethodsA 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.ResultsKnown groups comparison supports the construct validity of the CFS. The strong negative correlation between CFS and Barthel Index (rs = − 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).ConclusionThe Greek version of the CFS is a valid and reliable instrument for the identification of frailty in the Greek population.
Highlights
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
Cognitive status was assessed by using the Global Deterioration Scale, a 7-point scale ranging from no cognitive decline to very severe cognitive decline -severe dementia that can be broken down into three groups [40]
Two of them were reluctant to participate and for one more, who was unable to communicate, his caregiver denied to participate in the study
Summary
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. Among many screening tools that have been developed to detect frailty in older adults [5] Clinical Frailty Scale (CFS) is a valid, reliable and easy-to-use tool that allows health-care providers to assign a score based only on a standard clinical interview [6], and can be reliably used retrospectively [7]. It has been introduced as a seven-point scale, ranging from very fit to severely frail, with a visual chart that accompanied a description for each point of the scale [6]. It was expanded from a Vrettos et al BMC Geriatrics (2021) 21:393
