Resumo: | Introduction: The EQ-5D allows the achievement of two essential components of any measure of health-related quality of life to be used in cost-utility economic evaluations: (i) a profile describing the health status in terms of domains or dimensions; and (ii) a numeric value associated with the health status described.Aim: The Portuguese version of the EQ-5D questionnaire was completed in 1998, based on guidelines set by the EuroQol Group, including translation and back translation procedures. Despite its wide use in Portugal, until now it had not yet been published studies that initially led to the Portuguese version and the guarantee of acceptability, reliability and validity. The purpose of this article is to document these first values relating to the Portuguese version of the EQ-5D.Material and Methods: We used three different samples: a first one with 1,500 individuals representative of the Portuguese population; a second with 140 individuals just intended for the reliability test; and a third sample with 643 individual patients with cataracts, asthma, chronic obstructive pulmonary disease, or rheumatoid arthritis.Results: The acceptability was assessed by the number of missing responses. It was also found a marked ceiling effect, with a large part of the sample not reporting any problems in the dimensions of the EQ-5D.Discussion: The construct validity was tested by examining the degree to which low values of EQ-5D were positively associated with increasing age, being female, and the sick, as well as the values of dimensions of the SF-36v2 scale. Convergent validity was based on correlations between EQ-5D values and other specific measures. The EQ-5D showed moderate to high correlations with other diseasespecific measures of health status and health related quality of life.Conclusion: We can state that the Portuguese version of the EQ-5D has a good accessibility, reliability and validity in measuringhealth. |

Apesar da sua larga utilização em Portugal, até agora ainda não tinham sido publicados os estudos que conduziram inicialmente à versão portuguesa e à garantia de aceitabilidade, fiabilidade e validade. O propósito do presente artigo é, assim, documentar estes primeiros valores referentes à versão portuguesa do EQ-5D.Material e Métodos: Foram utilizadas três amostras diferentes: uma primeira com 1.500 indivíduos representativa da populaçãoportuguesa; uma segunda com 140 indivíduos apenas destinada ao teste da fiabilidade; e uma terceira amostra com 643 indivíduos doentes com cataratas, asma, doença pulmonar obstrutiva crónica ou artrite reumatoide.Resultados: A aceitabilidade foi avaliada pelo número de respostas em falta. Foi também encontrado um marcado efeito de teto com grande parte da amostra a não reportar quaisquer problemas nas dimensões do EQ-5D.Discussão: A validade de construção foi testada pela análise do grau com que valores baixos de EQ-5D estavam positivamente associados ao aumento da idade, ao ser do sexo feminino, e ao estar doente, assim como a valores de dimensões da escala SF-36v2. A validade convergente foi baseada nas correlações entre valores do EQ-5D e outras escalas específicas de condição de saúde. O EQ-5D apresentou correlações moderadas a altas com outras medidas de estado de saúde e de qualidade de vida relacionada com a saúde, específicas de cada doença.Conclusão: A versão portuguesa do EQ-5D tem uma boa aceitabilidade, fiabilidade e validade na medição do estado de saúde.Ordem dos Médicos2013-12-20info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/1317oai:ojs.www.actamedicaportuguesa.com:article/1317Acta Médica Portuguesa; Vol. 26 No. 6 (2013): November-December; 664-675Acta Médica Portuguesa; Vol. 26 N.º 6 (2013): Novembro-Dezembro; 664-6751646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/1317https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/1317/3807https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/1317/3908Ferreira, Pedro LopesFerreira, Lara NoronhaPereira, Luis Nobreinfo:eu-repo/semantics/openAccess2022-12-20T10:57:45Zoai:ojs.www.actamedicaportuguesa.com:article/1317Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:17:04.783437Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
