To adapt a questionnaire that assesses knowledge about heart failure (HF) and self-care and to analyze its content validity and reproducibility for use in Brazil. The questionnaire was validated through translation, summary, back-translation, expert committee review, pretest and assessment of psychometric properties. The final version (14 questions) was applied at the university hospital to HF outpatients under multidisciplinary team care. Five questions showed total agreement; seven scored Kappa > 0.4; one Kappa = 0.4, and just one presented no agreement. A group of 153 patients within 1-4 years of outpatient follow-up was assessed (age 59±13, 61% male). In the knowledge assessment, right answers varied from 4 to 14 (average 9.9±2.1). Results indicate the validity of the questionnaire for use in Brazil.
