RESUMEN
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. The factor loadings varied from 0.525 to 0.924. The internal intra-assessor consistency was satisfactory (ICC = 0.94, CI 95%). Total reliability was considered excellent (Cronbach's alpha = 0.914). CONCLUSIONS: The ECPICID-AVC is considered appropriate for using in Brazil.
