Objective: Numerous easy-to-apply and reliable tools have been developed for frailty detection with realizing the obvious importance of it. We aimed to evaluate the reliability and validity of the PRISMA-7 questionnaire in the Turkish community-dwelling older population, incorporating the geriatrician perspective. Materials and Methods: Upon application of the exclusion criteria, a total of 97 older patients were enrolled. All participants underwent a comprehensive geriatric assessment. After the necessary permissions were obtained, the Turkish version of PRISMA-7 was properly translated into Turkish with a forward-backward translation approach. The adaptation was made complied with the guideline recommendations. A reference tool, the Turkish version of the clinical frailty scale (CFS), was used for validation. Results: Median (interquartile range) age of participants was 72 (10) years, and 61 (62.9%) were female. According to CFS, 17.5% (n=17) patients were in the frail group, and 82.4% (n=80) were in the Robust/Vulnerable group. When we evaluated the concordance of PRISMA-7 and CFS, there was a moderate concordance (Cohen’s kappa: 0.589, p<0.001). At its optimal cut-off for differentiating frail from non-frail patients (≥3), the PRISMA-7 questionnaire had a sensitivity of 94.1% and a specificity of 82.5% (area under the curve: 0.956, p<0.001). For PRISMA-7 inter-rater and retest reliabilities, Cohen’s kappas were 0.615, p=0.03 & 1.0, p<0.001, respectively.
