Abstract
Objective: To validate the Health Vulnerability (HV) markers of people with Heart Failure (HF). Methods: Methodological study, consisting of the identification of the HV markers of the person with HF, construction of their constitutive and operational definitions and content validation by specialists. Nineteen judges, health professionals, with clinical experience, research and publications on the subject, from five Brazilian states (Ceará, Bahia, São Paulo, Rio de Janeiro and Santa Catarina) participated in the validation. For the analysis of agreement and reliability, the Content Validity Index (CVI) and the Binomial Test were calculated. Results: 49 markers were validated, grouped into subdimensions and then organized into three dimensions: Human person (socioeconomic and demographic situation, clinical profile, learning, health behaviors, mental health), Co-presences (social support, family ties) and Care (health technologies, health costs and health services). All had excellent CVI (≥ 0.78) and p> 0.05. Conclusion: The markers operationalized the HV phenomenon, as they presented adequate parameters of validity. Thus, they can subsidize the construction of research and care instruments.
