Abstract

OBJECTIVE: To validate a questionnaire to assess the impact of dementia on one of the household members. METHODS: Methodological study. The instrument was designed based on literature review, expert opinion, and researchers' experience and then applied to a non-probability convenience sample consisting of 262 family members who live daily with a person with dementia. The construct validity was studied by exploratory factor analysis, principal components method, with varimax rotation of the items. RESULTS: An instrument with 30 items was obtained, distributed in four dimensions: "Emotional dimension," "Economic dimension," "Family relations dimension," and "Support-seeking dimension." Factor analysis revealed a total explained variance of 54.96% and a total Cronbach's alpha of .899. CONCLUSIONS: The instrument presents high internal consistency, grouped into four dimensions, all closely related to the family's adaptation to the onset of dementia in one of its members.
