Introduction: Care for patients with cerebral palsy (CP) poses significant challenges, with emphasis on the crucial role of family involvement in patients' well-being. The Family Empowerment Scale (FES) assesses parents/caregivers' perception of their ability to promote and influence their children's development in three domains: family, service system and community.
Objectives: The objectives of this study were to translate the FES into Brazilian Portuguese, to develop a calculator for data transformation and analysis and to evaluate the psychometric properties of the scale with Brazilian caregivers of children and adolescents with CP.
Methods: Translation occurred in four stages: translation, synthesis, back-translation and review of the translated version. A calculator was then developed in the Excel program, to present data in absolute values and graphically for each subscale. Statistical analysis included Bland-Altman, Intraclass Correlation Coefficient (ICC), Internal Consistency, and Floor and Ceiling Effect.
Results: In total, 50 parents and caregivers participated to the measurement properties investigation, and the scale demonstrated good reliability for the family (ICC = 0.80) and services (ICC = 0.81) subscales, as well as for the overall scale (ICC = 0.88). The community subscale showed moderate reliability (ICC = 0.68), with an adequate Cronbach's alpha (0.89). The FES showed no ceiling or floor effects and a small limit of agreement. The data of all participants were analysed using the calculator.
Conclusion: The FES-Brazilian Portuguese presented good reliability for assessing family empowerment in caregivers of children and adolescents with CP in Brazil, offering insights into this construct and guiding family-centred interventions. In addition, the calculator could be viable for adequate management and dissemination of data.
