Introduction: Completion of the SARC-F questionnaire constitutes the obligatory first step in the diagnostic process of sarcopenia, according to the revised European consensus on the definition and diagnosis of sarcopenia published by the European Working Group on Sarcopenia in Older People2 (EWGSOP2). SARC-F has been recognized as the most up-to-date and coherent screening tool for sarcopenia. The aim of the study was to translate and to validate the Polish version of the SARC-F questionnaire.
Materials and Methods: The validation process was performed in two stages: 1) translation and intercultural adaptation and 2) clinical validation. The inclusion criteria were as follows: age ≥ 65 years, unimpaired mobility, and no cognitive impairment. The EWGSOP2 criteria were used to diagnose sarcopenia. Hand grip strength measurement, physical fitness test, and body weight composition analysis were conducted. Sensitivity, specificity, accuracy-likelihood ratios, and SARC-F predictive values were calculated using the EWGSOP2 criteria.
Results: Sixty-seven people participated in the study of whom 21% were diagnosed with sarcopenia (SARC-F score: ≥ 4). The reliability of the questionnaire based on the Cronbach’s alpha coefficient was 0.784. Sensitivity, specificity, and negative predictive values were 92.9%, 98.1%, and 98.1%, respectively.
Conclusion: The process of validating the SARC-F questionnaire against Polish conditions demonstrated its applicability as a simple and reliable tool for diagnosing sarcopenia in daily clinical practice with older adults.
