Resumo: | Introduction: The Alzheimer’s Disease Assessment Scale – Cognitive Subscale is a brief battery developed to assess cognitive functioning in Alzheimer’s disease that encompasses the core characteristics of cognitive decline (e.g. memory, language, praxis, constructive ability and orientation). The early detection, as well as the monitoring of cognitive decline along disease progression, is extremely important in clinical care and interventional research. The main goals of the present study were to analyze the psychometric properties of the Portuguese version of the Alzheimer’s Disease Assessment Scale – Cognitive Subscale, and to establish normative values for the Portuguese population.Material and Methods: The Portuguese version of Alzheimer’s Disease Assessment Scale – Cognitive Subscale was administered to 223 cognitively healthy participants according to a standard assessment protocol consisting of the Mini-Mental State Examination, the Montreal Cognitive Assessment and the Adults and Older Adults Functional Assessment Inventory. Normal performance on the assessment protocol was the inclusion criteria for the study.Results: The Alzheimer’s Disease Assessment Scale – Cognitive Subscale revealed good psychometric properties when used in the Portuguese population. Age was the main predictor of the Alzheimer’s Disease Assessment Scale – Cognitive Subscale total score (R2 = 0.123), whereas the influence of education level was lower (R2 = 0.027). These two variables explained 14.4% of the variance on the Alzheimer’s Disease Assessment Scale – Cognitive Subscale scores and were used to stratify the normative values for the Portuguese population presented here.Conclusion: On the total sample, the average total score in the Alzheimer’s Disease Assessment Scale – Cognitive Subscale was 6 points. The normative data were determined according to age and educational level as these were the sociodemographic variables that significantly contributed to the prediction of the Alzheimer’s Disease Assessment Scale – Cognitive Subscale total scores, explaining 14.4% of their variance. The normative data are of the utmost importance to ensure proper use of this battery in Portugal. |

Avalia as funções tipicamente mais comprometidas na doença de Alzheimer considerando os seguintes domínios cognitivos: memória, orientação, linguagem, praxia e capacidade construtiva. A deteção precoce das alterações cognitivas assim como a sua monitorização são fundamentais para a prática em ambos os contextos clínico e de investigação. O presente estudo tem como objetivos analisar as propriedades psicométricas da versão portuguesa da Escala de Avaliação da Doença de Alzheimer – subescala cognitiva e estabelecer dados normativos para a população portuguesa.Material e Métodos: A versão portuguesa da Escala de Avaliação da Doença de Alzheimer – subescala foi administrada a 223 participantes cognitivamente saudáveis. Todos os participantes foram avaliados com os seguintes instrumentos: Mini-Mental State Examination, Montreal Cognitive Assessment e Inventário de Avaliação Funcional de Adultos e Idosos. Considerou-se como critério para a inclusão no estudo obter um desempenho normal nestas três provas.Resultados: A Escala de Avaliação da Doença de Alzheimer – subescala revelou boas propriedades psicométricas quando utilizada na população portuguesa. A idade demonstrou ser o principal preditor do desempenho na Escala de Avaliação da Doença de Alzheimer – subescala (R2 = 0,123), tendo a escolaridade menor influência (R2 = 0,027). Em conjunto, estas variáveis sociodemográficas explicaram 14,4% da variância na pontuação total da Escala de Avaliação da Doença de Alzheimer – subescala, sendo ambas consideradas na estratificação dos dados normativos para a população portuguesa.Conclusão: A pontuação total média na Escala de Avaliação da Doença de Alzheimer – subescala foi de 6 pontos. Os dados normativos foram estabelecidos de acordo com a idade e escolaridade, sendo estas variáveis sociodemográficas as que mais contribuíram para a predição do desempenho na Escala de Avaliação da Doença de Alzheimer – subescala, explicando 14,4% da variância. Os dados normativos são de extrema importância para o uso adequado desta bateria em Portugal.Ordem dos Médicos2018-02-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfapplication/pdfapplication/mswordapplication/mswordapplication/mswordapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859oai:ojs.www.actamedicaportuguesa.com:article/8859Acta Médica Portuguesa; Vol. 31 No. 2 (2018): February; 94-100Acta Médica Portuguesa; Vol. 31 N.º 2 (2018): Fevereiro; 94-1001646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPengporhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/5353https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9312https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9316https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9876https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9877https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9878https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/8859/9918Direitos de Autor (c) 2018 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessNogueira, JoanaFreitas, SandraDuro, DianaTábuas-Pereira, MiguelGuerreiro, ManuelaAlmeida, JorgeSantana, Isabel2022-12-20T11:05:38Zoai:ojs.www.actamedicaportuguesa.com:article/8859Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:19:39.107870Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
