One of the most widespread treatments includes the combination of patient education, along with other components. At the educational level, the Fibromyalgia Knowledge Questionnaire (FKQ) is a tool that assesses knowledge of fibromyalgia. Objective: To obtain the translation and cultural adaptation of the FKQ questionnaire into Spanish, as well as its readability, in addition to knowing the relationship between knowledge of the disease and the level of disability. Method: In phase one, a translation-back translation and an evaluation of the readability of the questionnaire was carried out from INFLESZ, while in phase two, the questionnaire was passed to women with FM to detect their knowledge of the disease. A total of 49 women participated, with a mean age of 54.48 years. Results: The Spanish version of the FKQ questionnaire was rated by the participants in all its items as \u201cclear and understandable\u201d. The readability obtained by the questionnaire was similar to its original version, with both totals being in the \u201cnormal\u201d range, following the INFLESZ ranges. Regarding the patients\u2019 knowledge about FM, the component in which the highest score was obtained was physical activity (80% correct), while the one that obtained the worst score was knowledge about medication (50% correct). In addition, an inverse correlation was obtained between the FKQ and the FIQ (Fibromyalgia Impact Questionnaire) (r = \u22120.438; p &lt; 0.01). Conclusions: The FKQ has been translated and culturally adapted, obtaining a correct understanding by the participants, as well as a degree of readability similar to the original questionnaire. Furthermore, it was obtained that, the lower the level of knowledge of the sick person, the greater the disability.<\/jats:p>","DOI":"10.3390\/ijerph18147678","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T21:39:15Z","timestamp":1626730755000},"page":"7678","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Spanish Translation and Cultural Adaptation of the Fibromyalgia Knowledge Questionnaire"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9502-5486","authenticated-orcid":false,"given":"Mar\u00eda","family":"Mendoza-Mu\u00f1oz","sequence":"first","affiliation":[{"name":"Health, Economy, Motricity and Education Research Group (HEME), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1349-2203","authenticated-orcid":false,"given":"Miguel","family":"Rodal","sequence":"additional","affiliation":[{"name":"BioErgon Research Group, Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1736-0996","authenticated-orcid":false,"given":"Miguel \u00c1ngel","family":"Garc\u00eda-Gordillo","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Chile, Talca 3467987, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8774-3282","authenticated-orcid":false,"given":"\u00c1ngel","family":"Acevedo-Duque","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Chile, Talca 3467987, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judith","family":"Garc\u00eda-Matador","sequence":"additional","affiliation":[{"name":"Health, Economy, Motricity and Education Research Group (HEME), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7551-4554","authenticated-orcid":false,"given":"Jos\u00e9 Ignacio","family":"Calzada-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Health, Economy, Motricity and Education Research Group (HEME), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas","family":"Morenas-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Motor Control Research Group, Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"663","DOI":"10.1016\/0140-6736(92)92190-Q","article-title":"Fibromyalgia: The Copenhagen declaration","volume":"340","author":"Csillag","year":"1992","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"952","DOI":"10.1002\/art.23826","article-title":"Identifying the clinical domains of fibromyalgia: Contributions from clinician and patient Delphi exercises","volume":"59","author":"Mease","year":"2008","journal-title":"Arthritis Rheum."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1002\/art.1780330203","article-title":"The American College of Rheumatology 1990 Criteria for the Classification of Fibromyalgia.
