[Brazilian version of the Cornell depression scale in dementia].
OBJECTIVE
Translating and adapting the Cornell scale for depression in dementia to the Portuguese language and verifying the interrater and test-retest reliability of the translated and adapted version.


METHODS
The Cornell scale was translated into Portuguese and back translated into English. Divergences of translation were identified and discussed, resulting in a version which was submitted to a pre-test for cross-cultural adaptation. The final version was administered to a sample of 29 patients with probable AD and to their caregivers.


RESULTS
The Cornell Scale presented good interrater (Kappa=0,77; p<0,001) and test-retest reliability (Kappa=0,76; p<0,001). The final version was easy to administer and well understood by the caregivers.


CONCLUSIONS
The Brazilian version of the Cornell Scale is an instrument with good reliability to evaluate depression in patients with dementia. This tool will contribute to the evaluation and follow-up of depressed patients with dementia in our population and may also be used in multicentric studies with Brazilian population.
