Spanish Title: Confiabilidad de la escala de barreras para la rehabilitación cardiaca


Objective: To determine the internal consistency and the test-retest reproducibility of the barriers scale for cardiac rehabilitation in a Colombian population.
Methods: The study included 30 patients (66.6% male, mean age = 67.0 ± 11.0 years), who were subjected to a percutaneous revascularisation in the Bucaramanga Los Comuneros University Hospital, Colombia, completed the scale at two times, with an interval of two months between them. The Cronbach-alpha coefficients and the intra-class coefficients (ICC) were calculated.
Results: The internal consistency of the Colombian version of the scale and the barriers scale for cardiac rehabilitation was good (Cronbach-alpha = 0.84). The ICC found was 0.711 (95% CI; 0.423-0.860). The reproducibility by domains was as follows: for the logistic factor (ICC: 0.76; 95% CI; 0.56-0.88); for the comorbidities/functional state (ICC: 0.73; 95% CI; 0.51-0.86); for the health perception factor (ICC: 0.66; 95% CI; 0.38-0.83; and finally for the work/time conflicts factor (ICC: 0.56; 95% CI; 0.29-0.78). The mean score per patient was 2.3 ± 0.7 and 2.0 ± 0.7 in the first and second evaluation, respectively (p = .0071).
Conclusion: The barriers scale for cardiac rehabilitation has acceptable reliability in the Colombian population evaluated. The identification of barriers using this scale will help to develop strategies to increase the participation and adherence to cardiac rehabilitation programs focused on the real needs of the patients.
