The aim of this study was to create and validate UCLA GIT 2.0 for Portuguese patients with SSc. (2) Methods: A multi-center study was conducted enrolling SSc patients. UCLA GIT 2.0 was validated in Portuguese using reliability (internal consistency, item \u2013total correlation, and reproducibility) and validity (content, construct, and criterion) tests. Criterion tests included EQ-5D and SF-36v2. Social\u2013demographic and clinical data were collected. (3) Results: 102 SSc patients were included, 82.4% of them female, and with a mean sample age of 57.0 \u00b1 12.5 years old. The limited form of SSc was present in 62% of the patients and 56.9% had fewer than five years of disease duration. Almost 60% presented with SSc-GI involvement with a negative impact on quality of life. The means for SF-36v2 were 39.3 \u00b1 10.3 in the physical component summary and 47.5 \u00b1 12.1 in the mental component summary. Total GI score, reported as mild in 57.8% of the patients, was highly reliable (ICC = 0.912) and the Cronbach\u2019s alpha was 0.954. There was a high correlation between the total GI score and EQ-5D-5L and SF-36v2 scores. (4) Conclusion: The Portuguese version of UCLA GIT 2.0 showed good psychometric properties and can be used in research and clinical practice.<\/jats:p>","DOI":"10.3390\/ijerph20021553","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T02:04:45Z","timestamp":1673834685000},"page":"1553","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Creation and Validation of a Portuguese Version of the UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Tract Instrument"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9448-9542","authenticated-orcid":false,"given":"Pedro L.","family":"Ferreira","sequence":"first","affiliation":[{"name":"Centre for Health Studies and Research, Faculty of Economics, University of Coimbra, 3004-512 Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1159-0491","authenticated-orcid":false,"given":"In\u00eas","family":"Genrinho","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Tondela Viseu Hospital Centre, 3504-509 Viseu, Portugal"},{"name":"Rheumatology Department, Baixo Vouga Hospital Centre, 3810-164 Aveiro, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1562-4022","authenticated-orcid":false,"given":"T\u00e2nia","family":"Santiago","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Coimbra and University Health Center, 3004-512 Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana","family":"Carones","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Coimbra and University Health Center, 3004-512 Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carolina","family":"Mazeda","sequence":"additional","affiliation":[{"name":"Baixo Vouga Hospital Centre, Rheumatology Department, Egas Moniz Health Alliance, 3810-164 Aveiro, Portugal"},{"name":"EpiDoC Unit, CEDOC, NOVA Medical School, NOVA University of Lisbon, 1169-056 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4116-8964","authenticated-orcid":false,"given":"Anabela","family":"Barcelos","sequence":"additional","affiliation":[{"name":"Baixo Vouga Hospital Centre, Rheumatology Department, Egas Moniz Health Alliance, 3810-164 Aveiro, Portugal"},{"name":"EpiDoC Unit, CEDOC, NOVA Medical School, NOVA University of Lisbon, 1169-056 Lisbon, Portugal"},{"name":"Comprehensive Health Research Center (CHRC), NOVA University of Lisbon, 1169-056 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiago","family":"Beir\u00e3o","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Vila Nova de Gaia\/Espinho Hospital Centre, 4434-502 Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8231-7110","authenticated-orcid":false,"given":"Fl\u00e1vio","family":"Costa","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Vila Nova de Gaia\/Espinho Hospital Centre, 4434-502 Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"In\u00eas","family":"Santos","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Tondela Viseu Hospital Centre Hospital Centre, 3460-525 Tondela, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maura","family":"Couto","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Tondela Viseu Hospital Centre Hospital Centre, 3460-525 Tondela, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Rato","sequence":"additional","affiliation":[{"name":"Rheumatology Department, S\u00e3o Jo\u00e3o University Hospital Centre Hospital Centre, 4200-319 Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgina","family":"Terroso","sequence":"additional","affiliation":[{"name":"Rheumatology Department, S\u00e3o Jo\u00e3o University Hospital Centre Hospital Centre, 4200-319 Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Rheumatology Department, Tondela Viseu Hospital Centre Hospital Centre, 3460-525 Tondela, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,14]]},"reference":[{"key":"ref_1","first-page":"260","article-title":"Digestive manifestations in systemic sclerosis","volume":"153","author":"Attar","year":"2002","journal-title":"Ann.
