Validity of Japanese Version of SARC-F Questionnaire in Patients with Chronic Liver Disease.
Journal of Gastroenterology and Hepatology 2018 August 26
BACKGROUND AND AIM: We aimed to examine the validity of the Japanese version of the SARC-F questionnaire (SARC-F-J) that employs the diagnostic criteria for sarcopenia established by the Japan Society of Hepatology in patients with chronic liver disease.
METHODS: Subjects were outpatients at the Department of Hepatology at the Japanese Red Cross Ise Hospital, Japan. Evaluations were performed using the following self-administered questionnaires: SARC-F-J, Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC), the Japanese version of the Falls efficacy scale (FES), and Kaigo-Yobo checklist (CL). Based on the diagnostic criteria of the Japan Society of Hepatology, we diagnosed sarcopenia from the skeletal muscle index calculated using the iliopsoas muscle area at the third lumbar vertebra on computed tomography and from grip strength. To evaluate construct validity, we calculated the sensitivity, specificity, and positive and negative predictive values of SARC-F-J that used the diagnostic criteria of the Japan Society of Hepatology as reference. Furthermore, to evaluate convergent validity, we calculated Pearson's correlation coefficients between SARC-F-J and TMIG-IC, FES, and CL.
RESULTS: A total of 140 subjects were included in the analysis set. Sensitivity and specificity were 16.3% and 45.0% and 95.3% and 90.8% for men and women, respectively. The positive predictive value was 81.8% for both, whereas the negative predictive value was 47.1% and 64.5% for men and women, respectively. A significant correlation was seen between SARC-F-J and TMIG-IC, FES, and CL.
CONCLUSIONS: We believe that the SARC-F-J is a valid tool for patients with chronic liver disease.
