Conclusions The TFI has the most robust evidence of reliability and validity and has been the most extensively examined in terms of psychometric properties .
However , there is insufficient evidence at present to determine the best tool for use in research and clinical practice .
Background Frailty is widely recognised as a distinct multifactorial clinical syndrome that implies vulnerability .
The links between frailty and adverse outcomes such as death and institutionalisation have been widely evidence d. There is currently no gold st and ard frailty assessment tool ; optimizing the assessment of frailty in older people therefore remains a research priority .
The objective of this systematic review is to identify existing multi-component frailty assessment tools that were specifically developed to assess frailty in adults aged ≥60 years old and to systematic ally and critically evaluate the reliability and validity of these tools .
Cross-cultural adaptation and reliability testing of the Tilburg Frailty Indicator for optimizing care of Polish patients with frailty syndrome
Background Frail older people are at high risk of developing adverse outcomes , such as disability , mortality , hospitalization , and institutionalization . Previous research suggests that the Tilburg Frailty Indicator ( TFI ) is a valid and reliable instrument for measuring frailty . The aim of this study was to adapt and to test the reliability of the Polish version of the TFI . Method A st and ard guideline was used for translation and cultural adaptation of the English version of the TFI into Polish . The study included 100 Polish patients ( mean age 68.2±6.5 years ) , among them 42 men and 58 women .  Cronbach ’s alpha was used for analysis of the internal consistency of the TFI . Results The mean total TFI score was 6.7±3.1 . Forty patients scored ≥5 , which corresponded to being frail . Cronbach ’s alpha reliability coefficients of the instrument ranged from 0.68 to 0.72 and item-total correlation ranged from 0.12 to 0.52 . Conclusion The TFI is valid and reproducible for assessment of frailty syndrome among a Polish population . The Polish adaptation of the TFI proved a useful and fast tool for assessing frailty
