ROMANIAN TRANSLATION AND VALIDATION OF THE SARC-F QUESTIONNAIRE.

ABSTRACT

CONTEXT Several studies have addressed the impact of sarcopenia on various health outcomes. As the most critical issue is the early identification of individuals, a short screening tool may help clinicians to simply test for sarcopenia and start early management of the disease. Recently, a simple questionnaire, Sarc-F was provided that may adequately realize this aim. SUBJECTS AND METHODS: To validate the questionnaire we translated the original Sarc-F according to the recommended methodology. A total of 80 people, aged 65+ were evaluated for sarcopenia. Muscle mass, strength, and physical performance were measured. Volunteers completed the Sarc-F as well as other two questionnaires. Discriminative power, reliability, construct validity analyses, specificity, sensitivity, negative and positive predictive value evaluations were made. RESULTS: A good discriminative power and internal consistency were found. With the functional sarcopenia diagnostic criteria the test demonstrates a high specificity (84%). The positive and negative predictive values were 78% and 77%. Using the more conservative diagnostic criteria the negative predictive value was 85.4%, sufficient to rule out those not at risk of having sarcopenia and eliminate the need for further investigations. CONCLUSIONS: A valid Romanian Sarc-F questionnaire is now available to simply detect patients at risk/no risk of sarcopenia.
