{"doi":"10.1002/mdc3.14236","title":"Validation of the Portuguese <scp>MDS</scp>‐<scp>UPDRS</scp>: Challenges to Obtain a Scale Applicable to Different Linguistic Cultures","abstract":"BACKGROUND: The MDS-UPDRS has been available in English since 2008, showing satisfactory clinimetric results and being proposed as the new official benchmark scale for Parkinson's disease (PD), being cited as a core instrument for PD in the National Institutes of Neurological Disorders and Stroke Common Data Elements program. For this reason, the MDS created guidelines for development of MDS-UPDRS official, clinimetrically validated translations. OBJECTIVE: This study presents the formal process used to obtain the officially approved Portuguese version of the MDS-UPDRS. METHODS: The study consisted of three phases: (1) Independent translation by Portuguese and Brazilian teams followed by a challenging consensus process that this article particularly emphasizes; (2) Cognitive pretest involving raters and patients from both Portugal and Brazil; (3) Validation test with a sample of 367 native Portuguese-speaking PD patients. RESULTS: The overall factor structure of the Portuguese version was consistent with the English version based on a comparative fit index ≥0.96 for all four parts of the MDS-UPDRS. CONCLUSION: This version can be designated as the official Portuguese version of the MDS-UPDRS.","journal":"Movement Disorders Clinical Practice","year":2024,"id":450838,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9009,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1271321,"name":"Thiago Cardoso Vale","orcid":"0000-0001-6145-9868","position":1,"is_corresponding":false},{"id":644711,"name":"Leonor Correia Guedes","orcid":"0000-0002-8422-0494","position":2,"is_corresponding":false},{"id":936099,"name":"Ricardo Maciel","orcid":"0000-0003-0027-280X","position":3,"is_corresponding":false},{"id":1271322,"name":"Ana Antunes","orcid":"0000-0002-6277-6037","position":4,"is_corresponding":false},{"id":760632,"name":"Sarah Camargos","orcid":"0000-0001-9829-6783","position":5,"is_corresponding":false},{"id":1271323,"name":"Anabela Valadas","orcid":"0000-0001-6359-6110","position":6,"is_corresponding":false},{"id":1271324,"name":"Miguel Coelho","orcid":"0000-0002-4008-8110","position":7,"is_corresponding":false},{"id":1271325,"name":"Catarina Godinho","orcid":"0000-0003-2304-3129","position":8,"is_corresponding":false},{"id":1064947,"name":"Débora Palma Maia","orcid":"0000-0003-3089-2911","position":9,"is_corresponding":false},{"id":1271326,"name":"Patrícia Lobo","orcid":"0000-0002-7815-3504","position":10,"is_corresponding":false},{"id":1271811,"name":"Raphael Doyle Maia","orcid":null,"position":11,"is_corresponding":false},{"id":1271327,"name":"Tiago Teodoro","orcid":"0000-0003-4501-5532","position":12,"is_corresponding":false},{"id":563689,"name":"Carlos Roberto de Mello Rieder","orcid":"0000-0003-2950-7211","position":13,"is_corresponding":false},{"id":1271328,"name":"Ana Graça Velon","orcid":"0000-0001-9273-6688","position":14,"is_corresponding":false},{"id":1271812,"name":"Maria José Rosas","orcid":null,"position":15,"is_corresponding":false},{"id":1271813,"name":"Ana Calado","orcid":null,"position":16,"is_corresponding":false},{"id":1271329,"name":"Verónica Caniça","orcid":"0009-0006-5928-7415","position":17,"is_corresponding":false},{"id":1271814,"name":"José Vale","orcid":null,"position":18,"is_corresponding":false},{"id":209546,"name":"Alexandre Mendes","orcid":null,"position":19,"is_corresponding":false},{"id":1271330,"name":"Margarida Rodrigues","orcid":"0000-0001-5005-5251","position":20,"is_corresponding":false},{"id":1271815,"name":"Maria Manuela Costa","orcid":null,"position":21,"is_corresponding":false},{"id":1271816,"name":"Tânia Lampreia","orcid":null,"position":22,"is_corresponding":false},{"id":563688,"name":"Henrique Ballalai Ferraz","orcid":"0000-0002-3821-1407","position":23,"is_corresponding":false},{"id":563686,"name":"Vítor Tumas","orcid":"0000-0003-2402-2709","position":24,"is_corresponding":false},{"id":289900,"name":"Egberto Reis Barbosa","orcid":"0000-0002-6996-9130","position":25,"is_corresponding":false},{"id":92181,"name":"Glenn T.
