Abstract
No Brazilian version of a specific scale for evaluating apathy in dementia is available.
Objectives:
To introduce a translated version of the Apathy Scale (AS) for use with caregivers.
Methods:
The instrument was formally translated and then administered to the caregivers of a small sample of dementia patients, in order to assess scale comprehensibility and make final adjustments. The scale was subsequently administered to the caregivers of a second, independent sample of Alzheimer's disease (AD) patients. The content validity of the scale was tested by correlating the AS scores with the Neuropsychiatric Inventory (NPI) - apathy sub-score and Disability Assessment in Dementia (DAD) total scores.
Results:
The first sample consisted of eleven subjects with dementia, most of whom had AD. The second sample comprised twenty patients with probable or possible AD (10 with mild dementia), a mean age of 84.1±5.8 years, and 2.2±1.6 years of schooling. The AS scores correlated with both NPI-apathy sub-score (r=0.756, p=0.001) and DAD total scores (r=-0.793, p=0.0005).
Conclusions:
The final version had good comprehensibility and correlated strongly with standardized apathy and functional activities of daily living measures.
Key words:
apathy; diagnosis; evaluation; dementia; Alzheimer's disease.
Resumo
Não há versão brasileira de qualquer escala especificamente dedicada à avaliação de apatia nas demências.
Objetivos:
Apresentar uma versão traduzida da Escala de Apatia direcionada ao cuidador.
Métodos:
O instrumento foi formalmente traduzido e administrado aos cuidadores de uma pequena amostra de pacientes com demência, para avaliar a compreensibilidade da versão e realizar ajustes finais. Em seguida a escala foi administrada aos cuidadores de uma segunda amostra independente de pacientes com doença de Alzheimer (DA). A validade de conteúdo da escala foi testada correlacionando-se os escores da Escala de Apatia com os subescores de apatia do Inventário Neuropsiquiátrico (NPI) e com os escores totais da escala DAD de incapacidade na demência.
Resultados:
A primeira amostra consistia de onze pacientes com demência, a maioria com doença de Alzheimer (DA). A segunda amostra possuía vinte pacientes com DA provável ou possível (10 com demência leve), média de idade de 84,1±5,8 anos e escolaridade média de 2,2±1,6 anos. Os escores na Escala de Apatia correlacionaram-se com o subescore apatia do NPI (r=0,756; p=0,001) e com os escores totais da DAD (r=-0,793; p=0,0005).
Conclusões:
A versão final apresentou boa compreensibilidade e correlacionou-se fortemente com medidas padronizadas de apatia e atividades de vida diária.
Palavras-chave:
