Purpose: To establish the scale reliability Self-care Agency Appreciation (SAA) of Evers and Isenberg, second version in Spanish, and to describe the capacity of self-care agency among people with cardiovascular factor risks who attend the out-patient chronic patients program service of a hospital in Bogota, Colombia. Method: descriptive design with a quantitative approach that enabled us to evaluate the self-care agency capacity in a sample of 201 patients with cardiovascular risk factors who attended the chronic patients program of a hospital in Bogota, through the use of the SAA scale, second version in Spanish. Reliability was measured thru this scale by calculating the alfa-Cronbach's reliability coefficient value. Results: it was found that 35,8% of the participants had a good self-care agency capability and 62,6%, an average one. The alfa-Cronbach's reliability coefficient was applied to the SAA scale and a value of 0,744 was obtained. Conclusions: A difference of 0,026 is observed below the value reported in the reliability measure of the SAA scale carried out by doctor Gallegos, first version in Spanish, within a Mexican context; these results mean that the 24 items of the scale analyzed measure the same concept and therefore one concludes that the instrument has internal consistency.
