The aim of the study was to translate, adapt, and validate the Polish version of the SARC-F for community-dwelling older adults in Poland.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Materials and methods<\/jats:title>\n<jats:p>We included 160 Polish volunteers aged \u2265 60 years (44% of men). The Polish version of SARC-F was adapted following standardized forward-backward translation procedure. SARC-F was validated against the six sets of diagnostic criteria as the reference standards [developed independently by European Working Group on Sarcopenia in Older People1 (EWGSOP1), European Working Group on Sarcopenia in Older People2 (EWGSOP2), Foundation for the National Institutes of Health (FNIH) Sarcopenia Project, Asia Working Group for Sarcopenia (AWGS), the International Working Group for Sarcopenia (IWGS), and Society on Sarcopenia, Cachexia and Wasting Disorders (SCWD)].<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>SARC-F score \u2265 4 points was observed in 18.8% of the study population. Cronbach\u2019s alpha was 0.70. The sensitivity of SARC-F varied from 33.3% to 50.0% depending on the diagnostics criteria used, while the specificity was about 85%. Positive predictive value (PPV) was low (about 30%) for five out of six sets of the diagnostic criteria used (EWGSOP2, IWGS, AWGS, FNIH, and SCWD), while the negative predictive value (NPV) was generally high (&gt;88%). The area under the ROC curves (AUC) was 0.652\u20130.728. SARC-F had the largest AUC against FNIH criteria (0.728), indicating a moderate diagnostic accuracy. Similar results were found for EWGSOP2 and IWGS criteria. The AUC values were below 0.7 for AWGS, SCWD, and EWGSOP1 criteria.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>Based on the results, the Polish version of SARC-F shows excellent reliability and good internal consistency. High specificity and high NPV make SARC-F a useful tool to rule-out sarcopenia with high accuracy in community-dwelling older adults, independently of the diagnostic criteria used.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0244001","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T18:47:30Z","timestamp":1608576450000},"page":"e0244001","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":13,"title":["Polish version of SARC-F to assess sarcopenia in older adults: An examination of reliability and validity"],"prefix":"10.1371","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6770-7321","authenticated-orcid":true,"given":"Roma","family":"Krzymi\u0144ska-Siemaszko","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewa","family":"Deskur-\u015amielecka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Kalu\u017aniak-Szymanowska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arkadiusz","family":"Styszy\u0144ski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Wieczorowska-Tobis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2020,12,21]]},"reference":[{"issue":"1","key":"pone.0244001.ref001","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1093\/ageing\/afy169","article-title":"Sarcopenia: Revised European Consensus on Definition and Diagnosis","volume":"48","author":"AJ Cruz-Jentoft","year":"2019","journal-title":"Age Ageing"},{"issue":"8","key":"pone.0244001.ref002","doi-asserted-by":"crossref","first-page":"531","DOI":"10.1016\/j.jamda.2013.05.018","article-title":"SARC-F: A Simple Questionnaire to Rapidly Diagnose Sarcopenia","volume":"14","author":"TK Malmstrom","year":"2013","journal-title":"J Am Med Dir Assoc"},{"issue":"Suppl 1","key":"pone.0244001.ref003","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1111\/ggi.12197","article-title":"Development of a Simple Screening Test for Sarcopenia in Older Adults","volume":"14","author":"S Ishii","year":"2014","journal-title":"Geriatr Gerontol Int"},{"issue":"6","key":"pone.0244001.ref004","doi-asserted-by":"crossref","first-page":"743","DOI":"10.1007\/s12603-017-0921-4","article-title":"Assessing the Risk of Sarcopenia in the Elderly: The Mini Sarcopenia Risk Assessment (MSRA) Questionnaire","volume":"21","author":"AP Rossi","year":"2017","journal-title":"J Nutr Health Aging"},{"issue":"4","key":"pone.0244001.ref005","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1093\/ageing\/afq034","article-title":"Sarcopenia: European Consensus on Definition and Diagnosis: Report of the European Working Group on Sarcopenia in Older People","volume":"39","author":"AJ Cruz-Jentoft","year":"2010","journal-title":"Age Ageing"},{"issue":"5","key":"pone.0244001.ref006","doi-asserted-by":"crossref","first-page":"547","DOI":"10.1093\/gerona\/glu010","article-title":"The FNIH Sarcopenia Project: Rationale, Study Description, Conference Recommendations, and Final Estimates","volume":"69","author":"SA Studenski","year":"2014","journal-title":"J Gerontol A Biol Sci Med Sci"},{"issue":"2","key":"pone.0244001.ref007","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1016\/j.jamda.2013.11.025","article-title":"Sarcopenia in Asia: Consensus Report of the Asian Working Group for Sarcopenia","volume":"15","author":"LK Chen","year":"2014","journal-title":"J Am Med Dir Assoc"},{"issue":"4","key":"pone.0244001.ref008","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1016\/j.jamda.2011.01.003","article-title":"Sarcopenia: An Undiagnosed Condition in Older Adults.
