Objectives: Familism is a cultural value that has been shown to be important for understanding the dementia caregiving process. The aim of this study is to analyze the psychometric properties of the Revised Familism Scale (RFS).; Method: Face-to-face assessments were done with 199 dementia family caregivers. Exploratory factor analysis, discriminant validity, and reliability analyses of the RFS were carried out.; Results: The results suggest that the RFS has good psychometric properties and is composed of three factors: "Familial interconnectedness", "Familial obligations", and "Extended family support".; Conclusion: The RFS seems to be a reliable measure of familism, a multidimensional construct measuring a relevant cultural value for dementia family caregivers.
