Background The levels of frailty are anticipated to increase as a result of population aging. A valid instrument is required to detect individuals at high risk of frailty. The present research aimed to assess feasibility, reliability, and construct validity of the Arabic version of Groningen Frailty Indicator (GFI) in urban and rural populations in South Lebanon. Methods During 2015, a cross-sectional study, which enrolled 390 community-dwelling individuals aged 65 years and above, was conducted in urban and rural areas in Nabatieh in South Lebanon. The survey included questions on sociodemographic and health-related characteristics, GFI, and Vulnerable Elders Survey-13 (VES-13). The translation and cultural adaptation of the GFI followed a standardized protocol. After that, the psychometric properties of the scale (i.e., feasibility, reliability, and validity) were evaluated. Results A total of 390 elderly filled out the questionnaire, of whom 51% were women and 70% lived in rural ...
Psychometric evaluation of the Persian version of the Successful Aging Inventory
Galen Medical Journal
Background: The first step to successful aging planning is to assess the current status using valid instruments. This study aimed to evaluate the psychometric properties of the Persian version of the Successful Aging Inventory (SAI). Materials and Methods: In the first step, SAI. was translated through forward-backward translation, and its face and content validity were qualitatively and quantitatively assessed. For construct validity assessment, 300 elderly were recruited through multi-stage random sampling. Exploratory factor analysis and known-group comparison were used. SAI reliability through internal consistency and stability was assessed using the Cronbach’s alpha values of the inventory and intraclass correlation coefficient (ICC), respectively. The standard error of measurement, smallest detectable change, and floor and ceiling effects were calculated. Results: The impact scores, content validity ratios, and content validity indices of all items were more than 1.5, 0.62, an...
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 standard 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.
Assessing Frailty with the Tilburg Frailty Indicator (TFI): A Review of Reliability and Validity
Clinical Interventions in Aging
Objective: The Tilburg Frailty Instrument (TFI) is an instrument for assessing frailty in community-dwelling older people. Since its development, many studies have been carried out examining the psychometric properties. The aim of this study was to provide a review of the main findings with regard to the reliability and validity of the TFI. Methods: We conducted a literature search in the PubMed and CINAHL databases on May 30, 2020. An inclusion criterion was the use of the entire TFI, part B, referring to the 15 components. No restrictions were placed on language or year of publication. Results: In total, 27 studies reported about the psychometric properties of the TFI. By far, most of the studies (n = 25) were focused on community-dwelling older people. Many studies showed that the internal consistency and test-retest reliability are good, which also applies for the criterion and construct validity. In many studies, adverse outcomes of interest were disability, increased health-care utilization, lower quality of life, and mortality. Regarding disability, studies predominantly show results that are excellent, with an area under the curve (AUC) >0.80. In addition, the TFI showed good associations with lower quality of life and the findings concerning mortality were at least acceptable. However, the association of the TFI with some indicators of health-care utilization can be indicated as poor (eg, visits to a general practitioner, hospitalization). Conclusion: Since population aging is occurring all over the world, it is important that the TFI is available and well known that it is a user-friendly instrument for assessing frailty and its psychometric properties being qualified as good. The findings of this assessment can support health-care professionals in selecting interventions to reduce frailty and delay its adverse outcomes, such as disability and lower quality of life.

To present the translation and validation process of the Portuguese version of the Tilburg Frailty Indicator (TFI). Methods: A cross-sectional study was designed using a non-probability sample of 252 community-dwelling older adults. Preliminary studies were carried out for face and content validity assessment. Internal consistency, test-retest reliability, construct (convergent/divergent) and criterion validity were subsequently analyzed. Results: The sample was mainly women (75.8%), with a mean age of 79.2 ± 7.3 years. TFI internal consistency was good (KR-20 = 0.78). Test-retest reliability for the total was also good (r = 0.91), with kappa coefficients showing substantial agreement for most items. TFI physical and social domains correlated as expected with concurrent measures, whereas the TFI psychological domain showed similar correlations with other psychological and physical measures. The TFI showed a good to excellent discrimination ability in regard to frailty criteria, and fair to good ability to predict adverse outcomes. Conclusions: The psychometric properties of the TFI seem to be consistently good. These findings provide initial evidence that the Portuguese version is a valid and reliable measure for assessing frailty in the elderly.
Turkish version of the Tilburg Frailty Indicator
Clinical Interventions in Aging, 2019
Background: Recently frailty has drawn significant interest as an important predictor of several clinically relevant outcomes. There is no widely accepted instrument for the assessment of frailty and most of the current ones evaluate only physical features. The Tilburg Frailty Indicator (TFI) is a valid and reliable instrument which enables multidimensional assessment of frailty. We aimed to adapt and evaluate the Turkish version of the TFI. Methods: We translated and culturally adapted the English version of the TFI into Turkish using standard guidelines. We enrolled consecutive patients who were 70 years old or older and were admitted to our outpatient geriatrics clinic. We used Cronbach's alpha values to evaluate the internal consistency and also assessed inter-observer and test-retest variability using intraclass correlation coefficient (ICC). Results: The Cronbach's alpha reliability coefficients of the instrument ranged from 0.65 to 0.72 and item-total correlation ranged between-0.05 and 0.57. There was a good agreement between two assessments (ICC=0.99) and between two observers (ICC=0.99). Conclusion: We have shown the reliability of the Turkish version of the TFI as a tool to evaluate frailty in a multidimensional manner among the Turkish outpatient population.

Primary health care may play an important role in identifying persons at risk for frailty. The Groningen Frailty Indicator (GFI) is considered a valid instrument to assess frailty in old age. However, it is not tested yet in a different cultural context. The aim of this study is to analyse the construct, content and criterion validity of the GFI in independent-living old Romanians. Twenty-two GPs participated in this study. They have sent he GFI questionnaire to 215 patients of 65 years and over. The GPs assessed the frailty of the patients, independently from the questionnaire. The mean age of the respondents was 74.9 years. The mean GFI score was 5.5 (SD 2.9). Three-quarters of the respondents fit into the 'moderate' or 'severe' frailty category. Citizens 80 years old and older scored higher in terms of frailty. Ninety-eight per cent of the respondents completed at least 75% of the GFI items. The construct validity was good (Cronbach's alpha 0.746). All the ite...
Exploring the efficiency of the Tilburg Frailty Indicator: a review
Clinical interventions in aging, 2017
Due to rapidly aging human populations, frailty has become an essential concept, as it identifies older people who have higher risk of adverse outcomes, such as disability, institutionalization, lower quality of life, and premature death. The Tilburg Frailty Indicator (TFI) is a user-friendly questionnaire based on a multidimensional approach to frailty, assessing physical, psychologic, and social aspects of human functioning. This review aims to explore the efficiency of the TFI in assessing frailty as a means to carry out research into the antecedents and consequences of frailty, and its use both in daily practice and for future intervention studies. Using a multidimensional approach to frailty, in contexts where health care professionals or researchers may have no time to interview or examine the client, we recommend employing the TFI because there is robust evidence of its reliability and validity and it is easy and quick to administer. More studies are needed to establish wheth...
Validation of the revised 9-scale clinical frailty scale (CFS) in Greek language
BMC Geriatrics, 2021
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 (rs = − 0,725, p ≤ 0.001), supports the criterion concurrent validity of the instrument. The intr...
