RODRIGUEZ-GAZQUEZ, María de los Ángeles  e  ARREDONDO-HOLGUIN, Edith. Validity and Reliability of a Scale for Rating Self-care in Persons with Heart Failure. Aquichan [online]. 2012, vol.12, n.1, pp.22-31. ISSN 1657-5997.

Objective: The purpose of this study is to determine the validity and reliability, in the Colombian context, of a scale designed by Nancy Artinian to rate self-care among persons with heart failure (HF). Method: This is a validation study of the Revised Heart Failure Self-care Behavior Scale. A cultural validation was done (n = 13 nurses who are experts in cardiovascular care and 12 patients with HF), along with factor validation and a reliability analysis (n = 206 patients with HF). Results: The cultural validation of the scale was adequate. The factor evaluation showed the Spanish version had four domains (asking for help, adapting to living with the disease, adherence to pharmacological treatment, and adherence to non-pharmacological treatment) that explained 34.2% of the latent construct variance in the scale. Seven items that account for less than 0.2% of the variance were eliminated, leaving the final scale reduced to 21 items. The Cronbach alpha reliability coefficient for the entire scale was acceptable (0.75). Conclusion: The new version of the scale has adequate psychometric properties in terms of reliability and validity, allowing for its use by nurses to detect clinically important behavioral changes in self-care among patients with HF.
