ABSTRACT

Objective: We adapted the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) to Brazilian Portuguese, pilot testing it on mild and moderate patients with Alzheimer's disease (AD).

Methods: The cross-cultural process required six steps. Sixty-six patients with AD were assessed for competence to consent to treatment, global cognition, working memory, awareness of disease, functionality, depressive symptoms and dementia severity.

Results: The items had semantic, idiomatic, conceptual and experiential equivalence. We found no difference between mild and moderate patients with AD on the MacCAT-T domains. The linear regressions showed that reasoning (p = 0.000) and functional status (p = 0.003) were related to understanding. Understanding (p = 0.000) was related to appreciation and reasoning. Awareness of disease (p = 0.001) was related to expressing a choice.

Conclusions: The MacCAT-T adaptation was well-understood and the constructs of the original version were maintained. The results of the pilot study demonstrated an available Brazilian tool focused on decision-making capacity in AD.

RESUMO

Objetivo: Adaptamos o MacArthur Competence Assessment Tool for Treatment (MacCAT-T) para o português brasileiro, realizando estudo piloto em amostra de pessoas com doença de Alzheimer (DA) leve e moderada.

Métodos: O processo transcultural apresentou seis passos. Posteriormente, avaliamos competência para consentimento do tratamento, cognição global, memória de trabalho, consciência da doença, funcionalidade, sintomas depressivos e gravidade da doença de 66 pessoas com DA.

Resultados: Os itens apresentaram equivalência semântica, idiomática, conceitual e experiencial. Não encontramos diferenças entre pessoas com DA leve e moderada nos domínios do MacCAT-T. Regressões lineares demonstraram que raciocínio (p = 0.000) e funcionalidade (p = 0.003) estavam relacionados à compreensão. Compreensão (p = 0.000) estava relacionada ao julgamento e raciocínio. Consciência da doença (p = 0.001) estava relacionada à expressão da escolha.

Conclusões: A adaptação da MacCAT-T foi bem compreendida e os constructos da versão original mantidos. Resultados do estudo piloto apontaram disponibilidade de ferramenta brasileira sobre tomada de decisões na DA.
