    Abstract:
    This study aims to assess the reliability, construct validity (convergent/divergent), and criterion validity of the Italian version of the Tilburg Frailty Indicator (TFI). The TFI is a self-report questionnaire for screening frailty in older adults. Two hundred and sixty-seven community-dwelling older adults were involved. Psychometric properties were analyzed using validated instruments. Adverse outcomes such as disability, falls, and visits to a general practitioner were detected. Participants were mainly women (59.9%), with a mean age of 73.4 years (SD = 6.0). Internal consistency reliability was acceptable. Construct validity was good, since each item of the TFI correlated as expected with corresponding frailty measures. Convergent and divergent validity were adequate for all the domains of the TFI. Criterion validity was excellent for disability and mediocre for the other two outcomes. This study supports the validity of the Italian TFI and offers to clinicians and scientists a multidimensional instrument for identifying frail individuals in the Italian context.
