Objective:

To validate the “Minnesota Living with Heart Failure” quality of life questionnaire in patients with heart failure, for its use in a Colombian population.

Materials and methods:

An observational, prospective study with validation of a scale at three points was conducted. First of all, a translation, back-translation, and cultural adaptation were performed. This was followed by the evaluation of the content validity, construct, convergent and divergent criteria with the SF36, WHODAS II and DAS I questionnaires, as well as the assessment of internal consistency and the within- and between-observer reliability. Finally, a longitudinal study was carried out to evaluate the sensitivity to change.

Results:

The study included a total of 134 patients, with NYHA functional class I-IV, and an ejection fraction ≤ 50%. The confirmatory analysis was adjusted to the three dimensions of the original scale. There was a better quality of life in those that had a better physical capacity according to the MET achieved. The validity of the convergent criteria was greater than 0.6, with the divergent being less than 0.4 with the SF36, WHODAS II and DASI. Statistically significant differences were found between the beginning and the first, third, and sixth month. The minimum detectable change was for the physical dimension, 0.6, for the emotional dimension, 4.8, and for the total, 12.6.

Conclusions:

The “Minnesota Living with Heart Failure” scale is valid and reliable, and has a good sensitivity to change, in order to be used in the populations with heart failure in Colombia.
