Confiabilidad y validez de la escala para medir la contribución del cuidador al autocuidado del paciente con insuficiencia cardiaca
Abstract
Objective: To determine the reliability and validity of the Spanish version of the scale to measure the caregiver s contribution to self-care of patients with heart failure (CC-SCHFI). Methodology: Methodological study, with quantitative approach; which included psychometric tests, applied to family caregivers of people with heart failure. The methodological recommendations of the International Test Commission were followed for the cultural adaptation of the translation-back-translation test, semantic adequacy, facial and content validity, reliability through internal consistency and construct validity). Results: An agreement was reached between experts according to the Fleiss Kappa of 0.44 in the relevance dimension, 0.41 in the relevant dimension and a content validity by standardized CVI method of 0.68. The internal consistency of the instrument was optimal with a Cronbach s Alpha coefficient = 0.950. The exploration of the construct yielded a structure of 6 components. Conclusions: A Spanish scale was available to address the phenomenon of the caregiver s contribution to the self-care of patients with heart failure, with a factorial analysis that showed that the items of the instrument tend to be grouped into two domains (maintenance and management of self-care) and not three, as proposed by the original instrument.
