Resiliência no tratamento de pacientes com insuficiência cardíaca: construção e validação do instrumento RES-IC 15

Abstract

Introduction: Heart failure is a chronic and devastating disease that requires multi-professional care for therapeutic success and a reduction in hospital admissions and years of life lost due to complications and the impact of the disease on activities of daily living. Resilience is a psychological construct that can contribute to positive health behaviors and better outcomes. Generic instruments for measuring resilience have been used to assess this construct in the follow-up of patients with heart failure. Objectives: To propose the construction of an instrument to measure resilience specifically for individuals with chronic heart failure; to carry out a Scoping Review of the main instruments used in research to measure resilience in patients with chronic cardiovascular diseases; to analyze the evidence of content validity of the resilience instrument specifically for patients with chronic heart failure. Method: This is a psychometric study based on Pasquali's methodology, structured around three main poles: theoretical, empirical and analytical. The Delphi technique was used to evaluate the responses of the experts, whose sample was obtained by convenience, in two rounds using the Google Docs tool with five-point Likert-type response options. The statistical analysis was presented in terms of frequency and percentage, and the individual and instrument Content Validity Index (CVI), Content Validity Ratio (CVR) and Cronbach's alpha were evaluated. Results: 16 health professionals took part in the evaluation of the instrument in the first round and 13 in the second round, including doctors, nurses and psychologists from all regions of the country. In the first round, the total CVI was 0.96, Cronbach's alpha was 0.82, but the content validity ratio (CVR=0.37) was not reached for all the criteria of the 15 items. Three items, where there was no consensus among the experts in their preparation, were re-evaluated in the second round, obtaining a CVR ranging from 0.69 to 1.00. Conclusion: The resilience measurement instrument named RES-IC 15, specific for patients with chronic heart failure, showed evidence of validity, however, it is necessary to apply this instrument to the population for which it is intended for its reproducibility.
