Family Nursing Practice Scale: Portuguese Language Translation, Cross-Cultural Adaptation, and Validation

Abstract

Studies of family nursing interventions have shown positive results for the health of individuals and families. To increase the availability of instruments that evaluate the practice of family nursing, this research adapted and validated the Family Nursing Practice Scale (FNPS) for use in Brazil with a sample of 144 hospital nurses using a cross-sectional design. The adaptation process involved back-translation, validation by a committee of experts, and semantic analysis. Content validity was analyzed through the content validity coefficient (CVC); construct validity was analyzed by exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and convergent and discriminant validation through average variance extracted (AVE). The reliability of the measure was evaluated using Cronbach's alpha index and composite reliability (CR). The results indicate that the adapted version of FNPS is recommended for family nursing research, education, or clinical practice with Brazilian nurses.
