Background and Purpose: The Portuguese instrument for informal caregivers' skills providing care of aged people after a stroke (ECPICID-AVC) evaluates the capacities that informal caregivers must have for supporting aged stroke survivors. The purpose was to adapt and validate the ECPICID-AVC to be used in Brazil. Methods: A methodological study was conducted. Results: The terms with the lowest degree of comprehension were adapted. The factor analysis suggested the exclusion of three items and that the remaining be grouped into six domains.
