Abstract
DAVILA, Fabián A. et al. Validation of the European Heart Failure Self-care Behaviour Scale. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.2, pp.105-109. Epub Dec 06, 2016. ISSN 0120-5633. https://doi.org/10.1016/j.rccar.2016.09.016.
Introduction:
Heart failure is a frequent condition, with exacerbations related to the ability to follow medical indications.
Objetive:
The goal is to determine the reliability and internal validity of a self-care scale in the Colombian city of Bogotá.
Material and methods:
Cross-sectional study. Te registers of the heart failure program were exported, general characteristics of the scale items were identified, they were transformed into 0-100 values and Cronbach's alpha coefficient (>0.7) was estimated, as well as the internal validity by intraclass correlation coefficient for unique measurements and the average (p < 0.05).
Results:
144 registers were reviewed, 30.6% of whom were female; most common comorbidities were arterial hypertension with 54.9%, atrial fibrillation with 35% and alterations of the thyroid function with 31%; only 9.2% presented low functional class. The scale showed appropriate confidence and internal validity values, the total self-care score was 48.30. Items with the highest score were ''I get a flu shot every year'' (61.19 points) and ''I weigh myself every
day'' (60.04 points); items with the lowest score were ''I take all medication as instructed'' (29.66 points) and ''I follow a low-salt diet'' (38.59 points).
Conclusions:
The self-care scale revealed appropriate confidence and internal validity for determining self-care in patients with heart failure in the city of Bogotá, Colombia. Further research is required to determine the concurrent validity with other instruments and prospective designs.
