Psychometric Properties of the Persian Version of the Gerontopole Frailty Screening Tool in the Elderly

Aims: This study aimed to translate and determine the psychometric properties of the Gerontopole Frailty Screening Tool in the elderly in Tehran. Instrument & Methods: This cross-sectional study assessed the validity and reliability of the translated Gerontopole Frailty Screening Tool. Eleven experts evaluated the content validity of tool in the elderly after re-translation into Persian. With ۲۱۴ elderly participants, we assessed convergent validity and concurrent validity. A receiver operating characteristic curve was used to determine sensitivity, specificity, and the cutoff point. Cohen’s Kappa was used to assess the external consistency of the tool, and Cronbach’s alpha was used to assess its internal consistency. Findings: The participants included ۴۴.۹% women and ۵۵.۱% men. The overall kappa coefficient between the two evaluators was ۰.۸۲۶, and the Cronbach’s alpha coefficient for the tool was estimated at ۰.۷۵۷. To determine convergent validity and concurrent validity, the correlations between the Gerontopole Frailty Screening Tool and the Stanford Questionnaire were ۰.۵۱۹, with Abbreviated Mental Test Score ۰.۲۴۷, with Mini Nutritional Assessment ۰.۲۱۴, and with Geriatric Depression Scale ۰.۲۵۸ (p<۰.۰۵). The known-groups validity was not significant based on age. Also, the sensitivity and specificity based on the receiver operating characteristic curve at cutoff point ۳ were ۷۵% and ۶۵.۸%, respectively. The area under the receiver operating characteristic curve was estimated to be ۰.۷۸۵. Conclusion: The Persian version of the Gerontopole Frailty Screening Tool is a valid and reliable instrument to determine frailty in Iranian elderly at the level of primary care.
