Objective: To adapt and validate a Brazilian Portuguese version of the European Heart Failure Self-Care Behavior Scale. Methods: The cross-cultural adaptation (translation, synthesis, back-translation, expert committee review, and pretesting) and validation (assessment of face validity, content validity, and internal consistency reliability) were carried out in accordance with the literature. The European Heart Failure Self-Care Behavior Scale assesses key components of self-care: recognition of the signs and symptoms of decompensated heart failure (HF) and decision-making when these signs and symptoms arise. It comprises 12 items (range 12-60, where lower scores indicate better self-care).Results: The sample comprised 124 HF patients with a mean age of 62.3 ± 12 years. The Cronbach's Alpha internal consistency was 0.70 and the intraclass correlation coefficient for reproducibility was 0.87. Conclusion: Face and content validity, internal consistency and reproducibility have lended validity and reliability for the use of the instrument in Brazil.Descriptors: Heart Failure; Self-care, Nursing Education; Validation Studies. Adaptación transcultural y validación de la European Heart Failure Self-care Behavior Scale para el Portugués de Brasil Objetivo: Adaptar y validar European Heart Failure Self-Care Behavior Scale para uso en lengua portuguesa de Brasil. Métodos: El proceso de adaptación cultural (traducción, síntesis, retro traducción, revisión por comité de expertos y pré test), validación (validez de facie, de contenido y confiabilidad) fue realizado según la literatura. La European Heart Failure Self-Care Behavior Scale evalúa los componentes-clave para el auto cuidado:
IntroductionRecent studies have emphasized the importance of systematic education on the disease and selfcare for patients with heart failure (1)(2) . The objectives of this process are to teach, strengthen, improve and constantly evaluate the abilities of patients to manage their self-care (1) . Systematic disease education contributes to the prevention of factors that might precipitate decompensation, thus reducing the number of readmissions (2) . However, information and guidance dispensed to patients in settings such as hospitals, heart failure clinics, and their own homes are not always evaluated with regard to the effectiveness of implementation (3) .In the context of heart failure, self-care can be defined as adherence to medication, lifestyle recommendations (diet and physical exercise), and disease management at the earliest signs of decompensation (3) . While several questionnaires are available for assessment of self-care and disease knowledge, there are few studies suggesting brief and practical tools targeted to heart failure patients (3)(4)(5) .In the scope of heart failure, self-care has been a focus of interest for the development of tools that could assess patient behaviors. The first such instrument, originally called the Self-management of Heart Failure Instrument, was developed by United States nurse researchers and was d...
