Frailty is a loss of human function in one or more physical, psychological, or social aspects. The purpose of this study was to establish the reliability and validity of the Arabic (Jordan) version of the Tilburg Frailty Indicator (TFI) in older Jordanian adults. A total of 109 participants from Irbid, Jordan were recruited. Reliability tests were conducted by determining the KR-20 values. The total score of the Arabic (Jordan) version of the TFI had good reliability (KR 20 = 0.77) and good convergent and divergent validity with the corresponding scales: physical-TFI and the SF36-physical function (r = -0.317), psychological-TFI and GDS (r = 0.458), and social-TFI and the SF 36-social function (r = -0.304). The Arabic (Jordan) version of the TFI is reliable and valid for use in Jordanian population.
