Validation of Questionnaire to Assess the Impact of Dementia on the Family - Revista Brasileira de Enfermagem
Revista Brasileira de Enfermagem. 04-15-2022;75:e20210232
To validate a questionnaire to assess the impact of dementia on one of the household members.
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.
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.
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.
