[Cross-cultural adaptation of the Disability Assessment for Dementia (DAD)].
The original version of the Disability Assessment for Dementia (DAD) was translated into Portuguese and back translated to English. The divergences of translation were identified and discussed, resulting in a version that was used in a preliminary investigation for cross-cultural adaptation. The final version was administered to 29 patients with mild to moderate probable Alzheimer's disease. The correlation coefficients of DAD were 0.929 and 0.932 for the inter-examiner and test-retest evaluations respectively. The reliability indexes were also high (Kappa 0.72 p<0.001 inter-examiners and 0.85 p<0.001 test-retest). The Brazilian version of DAD was easy to administer and had good reliability to assess the functional status of demented patients. It will contribute to the follow-up of these patients in our population. Moreover, it can be used in transcultural studies on functional abilities in dementia.
