Resumo: | Introduction: Appropriate management of fatigue relies upon comprehensive assessment instruments and timely delivery of targeted interventions. The aims of this study were to translate a commonly used English-language measure of fatigue in cancer patients (the Multidimensional Fatigue Symptom Inventory–Short-Form, or MFSI-SF) into European Portuguese and to evaluate the psychometric properties (internal consistency reliability, factorial structure, and discriminant, convergent and criterion concurrent validity) of the translated measure for use with Portuguese patients.Material and Methods: After translation and adaptation of the MFSI-SF to European Portuguese, 389 participants (68.38% women), with a mean age of 59.14 years, completed the study protocol. This sample included 148 patients in active cancer treatment from a cancer center and a community sample composed of 55 cancer survivors, 75 patients with other chronic diseases, and 111 healthy controls.Results: The European Portuguese version of the Multidimensional Fatigue Symptom Inventory-Short Form (IMSF-FR) showed strong internal consistency (Cronbach’s alpha = 0.97, McDonald’s omega = 0.95). An exploratory factor analysis indicated that the items loaded in a 5-factor model in subscales were similar to the original version. Strong correlations between the IMSF-FR and other measures of fatigue and vitality confirmed convergent validity. Discriminant validity was supported by weak-to-moderate correlations between the IMSF-FR and measures of sleepiness, propensity to sleep, and lapses of attention and memory. The IMSF-FR accurately distinguished cancer patients from healthy controls and was able to differentiate clinician rated levels of performance among cancer patients.Conclusion: The IMFS-FR is a reliable and valid tool to assess cancer-related fatigue. By providing integrated comprehensive characterization of fatigue, this instrument may assist clinicians implementing targeted interventions. |

Os objetivos deste estudo foram traduzir uma medida internacional sobejamente usada na avaliação da fadiga (o Multidimensional Fatigue Symptom Inventory–Short-Form, ou MFSI-SF) para português-europeu e avaliar as propriedades psicométricas (consistência interna, estrutura fatorial, e validade discriminante, convergente e de critério, concorrente) daquele instrumento para pacientes portugueses.Material e Métodos: Após a tradução e adaptação do MFSI-SF para português-europeu, 389 participantes (68,38% mulheres), com uma média de idades de 59,14 anos, completaram o protocolo de estudo. Esta amostra incluiu 148 pacientes oncológicos em tratamento ativo de um hospital de oncologia e uma amostra comunitária composta por 55 sobreviventes oncológicos, 75 pacientes com outras doenças crónicas e 111 controlos saudáveis. Resultados: A versão portuguesa do Multidimensional Fatigue Symptom Inventory-Short Form (IMSF-FR) revelou uma forte consistência interna (alfa de Cronbach = 0.97, ómega de McDonald = 0.95). A análise fatorial exploratória indicou que os itens seguem um modelo de cinco fatores em subescalas idênticas à versão original. A validade convergente foi confirmada por relações fortes entre o IMSF-FR e outras medidas de fadiga e vitalidade. A validade discriminante foi sustentada por correlações fracas-a-moderadas entre o IMSF-FR e outras medidas de sonolência, propensão para a sonolência, e lapsos de atenção e memória. O IMSF-FR conseguiu distinguir corretamente doentes oncológicos e participantes saudáveis e predizer a capacidade funcional dos doentes oncológicos.Conclusão: Os resultados sugerem que o IMFS-FR é um instrumento válido e fiável para avaliar a fadiga em doentes oncológicos e outros doentes crónicos. Ao permitir uma caraterização integrada e compreensiva da fadiga, este instrumento pode assistir os profissionais de saúde a implementar intervenções específicas para a constelação de sintomas exibida.Ordem dos Médicos2023-02-22info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18797Acta Médica Portuguesa; Vol. 36 No. 11 (2023): November; 723-730Acta Médica Portuguesa; Vol. 36 N.º 11 (2023): Novembro; 723-7301646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18797https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/18797/15047Direitos de Autor (c) 2023 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessClara, Maria InêsStein, KevinCanavarro, Maria CristinaAllen Gomes, Ana2023-11-05T03:00:32Zoai:ojs.www.actamedicaportuguesa.com:article/18797Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:47:19.461532Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
