We aimed to translate and validate a Portuguese version of the FR-QoL-29. <b><i>Methods:<\/i><\/b> This was a case-control cross-sectional study undertaken at a tertiary hospital. After obtaining the original authors\u2019 authorization, both forward and backward translations of the original FR-QoL-29 were performed by bilingual researchers. After an IBD expert\u2019s revision and the input of a small group of patients, a final version was obtained. Portuguese IBD patients were prospectively recruited from the outpatient clinic of a tertiary hospital and completed the questionnaire at two timepoints (0 and 4 weeks). Reliability (internal consistency, test-retest, and intraclass correlation [ICC]), validity (content and convergent validity, and hypothesis testing using Spearman\u2019s correlations), and responsiveness (Student <i>t<\/i> tests) were analysed. <b><i>Results:<\/i><\/b> 239 patients (mean age 50.1 [SD = 15.3 years], 56.5% female) and 87 (36.4%) patients answered the questionnaire at the first and second timepoints, respectively; 126 controls answered the questionnaire. Overall, the FR-QoL-29-Portuguese showed excellent internal consistency (Cronbach\u2019s \u03b1 = 0.97) and good test-retest reliability (ICC = 0.78 [95% CI: 0.64\u20130.85]). FR-QoL moderately correlated with health-related quality of life, measured by the SIBDQ-PT (<i>R<\/i> = 0.49; <i>p<\/i> &lt; 0.05). Lastly, the questionnaire revealed appropriate responsiveness when patients reported an overall improvement in general well-being (mean improvement 25.88 [SD = 32.50]; <i>p<\/i> &lt; 0.05). <b><i>Discussion\/Conclusions:<\/i><\/b> We present an adaptation and validation of the FR-QoL-29 tool for Portuguese IBD patients. The FR-QoL-29-Portuguese is a reliable and valid tool shown to be responsive to changes in general well-being. <\/jats:p>","DOI":"10.1159\/000539227","type":"journal-article","created":{"date-parts":[[2024,6,6]],"date-time":"2024-06-06T11:45:37Z","timestamp":1717674337000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["Food-Related Quality of Life in Inflammatory Bowel Disease: Translation and Validation of Food-Related Quality of Life to the Portuguese Language (FR-QoL-29-Portuguese)"],"prefix":"10.1159","author":[{"given":"Raquel","family":"Oliveira","sequence":"first","affiliation":[]},{"given":"Viviana","family":"Martins","sequence":"additional","affiliation":[]},{"given":"Laetitia","family":"Teixeira","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6626-205X","authenticated-orcid":false,"given":"Helena","family":"Tavares de Sousa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5098-8729","authenticated-orcid":false,"given":"Joana","family":"Roseira","sequence":"additional","affiliation":[]}],"member":"127","published-online":{"date-parts":[[2024,6,6]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-1253(19)30333-4"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/ibd\/izx100"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2021.614653"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2020.12.031"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1111\/jhn.12668"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.appet.2021.105650"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3390\/nu13030759"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093\/ecco-jcc\/jjv192"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/nqaa395"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-019-02170-4"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1093\/ecco-jcc\/jjab116"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111\/jhn.12920"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093\/ibd\/izac010"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/s0016-5085(20)31781-9"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1186\/s12955-022-02014-9"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-010-9606-8"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2753.2010.01434.x"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.4103\/sja.SJA_203_17"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1007\/s10620-024-08333-9"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1186\/s12955-014-0176-2"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-018-2076-0"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1186\/s12955-021-01698-9"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijnurstu.2017.11.003"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1093\/ecco-jcc\/jjy114"}],"container-title":["GE - Portuguese Journal of Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/pjg\/article-pdf\/doi\/10.1159\/000539227\/4238585\/000539227.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/pjg\/article-pdf\/doi\/10.1159\/000539227\/4238585\/000539227.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:19:57Z","timestamp":1745421597000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000539227"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,6,6]]},"references-count":24,"URL":"https:\/\/doi.org\/10.1159\/000539227","archive":["Portico"],"relation":{},"ISSN":["2341-4545","2387-1954"],"issn-type":[{"type":"print","value":"2341-4545"},{"type":"electronic","value":"2387-1954"}],"subject":[],"published":{"date-parts":[[2024,6,6]]}}}
