Abstract
SANCHEZ-ROPERO, Eliana M. et al. Validation of a questionnaire for Measuring functional capacity in patients with heart failure in Colombia. Rev. Colomb. Cardiol. [online]. 2018, vol.25, n.6, pp.356-365. ISSN 0120-5633. https://doi.org/10.1016/j.rccar.2018.04.004.
Objectives:
To validate the Duke Activity Status Index questionnaire in patients with heart failure in Colombia.
Methods:
A translation to Spanish and a cultural adaptation was performed on the Duke Activity Status Index (DASI) questionnaire. A total 135 patients were included to carry out the content validity, with a confirmatory factor analysis. The convergent and divergent construct validity, and the criteria validity was evaluated, comparing New York Heart Association (NYHA) classification groups, and the correlations with the “Minnesota Living with Heart Failure Questionnaire” quality of life questionnaire, the SF-36 quality of life generic scale, and a questionnaire on the evaluation of disability by the World Health Organisation (WHO-DAS II). Internal consistency and inter-observer reliability was evaluated, as well as the sensitivity to change at one, three, and six months.
Results:
The scale is adjusted to two domains in the content validity. The convergent and divergent validity was verified, with significant correlations of the DASI with the scales that it was compared against. The criteria validity of the DASI with the NYHA classification showed some relationship, but it was not statistically significant. The Cronbach alpha was 0.69 in the internal consistency, and the inter-class correlation coefficients for inter-observer and within-observer reliability were 0.81 and 0.90, respectively.
Conclusions:
This version of the Duke Activity Status Index (DASI) in Spanish is valid and reliable for patients with heart failure in Colombia.
