Validation of Instrumento De Evaluación De La Experiencia Del Paciente Crónico for Brazilian Portuguese

Abstract

Objective: to analyze the metric properties of the Instrumento de Evaluación de la Experiencia del Paciente Crónico version adapted to Brazilian Portuguese. Method: this is a methodological and cross-sectional study conducted with 132 patients with chronic kidney disease on hemodialysis. Cronbach's alpha was used in the reliability assessment. Construct validity was assessed by means of Exploratory Factor Analysis and Confirmatory Factor Analysis. Results: the Instrumento de Evaluación de la Experiencia del Paciente Crónico tool obtained an overall Cronbach's alpha of 0.75. Unidimensionality of the instrument was recommended in the Exploratory Factor Analysis and confirmed through Confirmatory Factor Analysis, with the indices indicating good fits according to the established criteria. The results indicated the following values: χ2/g = 1.129; Goodness-of-Fit Index = 0.96; Root-Mean-Square Error of Approximation = 0.050; Tucker-Lewis Index = 0.97 and Adjusted Goodness-of-Fit Index = 0.94. Conclusion: the Instrumento de Evaluación de la Experiencia del Paciente Crónico tool shows diverse evidence of satisfactory reliability and validity in patients with chronic kidney disease undergoing hemodialysis.
