Abstract

Background and Objectives: This study aimed to translate and culturally adapt the Pictorial Fit–Frail Scale (PFFS) into Turkish and to evaluate its validity and reliability in older adults. Materials and Methods: The study included 156 community-dwelling older adults aged ≥ 65 years. Frailty status was determined using the Clinical Frailty Scale (CFS), and participants with a CFS ≥ 4 were classified as frail. All participants underwent the PFFS, Katz ADL, Lawton–Brody IADL, Short-Form Geriatric Depression Scale (GDS), Mini Nutritional Assessment—Short Form (MNA-SF), Standardized Mini-Mental State Examination (SMMSE), and Charlson Comorbidity Index (CCI). The reliability of the PFFS was assessed using internal consistency (Cronbach α), inter-rater reliability, and test–retest reliability (ICC); its construct validity was assessed using correlation analysis with the CFS. Furthermore, the diagnostic performance of PFFS in identifying frailty was analyzed using the ROC curve. Results: Of the 156 individuals participating in the study, 63.5% were women, and 89 individuals (57.1%) were frail. The Turkish version of PFFS showed high internal consistency (Cronbach α = 0.838). Inter-rater and test–retest reliability were found to be ICC = 0.995 and 0.996, respectively. A strong and positive correlation was found between PFFS and CFS scores (Spearman r = 0.760, p < 0.001). ROC analysis showed that PFFS had good performance in distinguishing frailty (AUC = 0.851, optimal cut-off ≥ 14; sensitivity = 69.7%, specificity = 83.6%). Frail individuals were older, had higher comorbidities, and showed greater dependence in activities of daily living. Conclusions: The Turkish version of the PFFS appears to be a reliable, valid, rapid, and multidimensional tool for assessing frailty in older adults. The PFFS can contribute to the effective assessment of frailty in clinical practice and research.
