What is the valid factor structure of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) in patients with heart failure?
The MLHFQ is a valid instrument for assessing physical, emotional, and social dimensions in patients with heart failure.
Our results support the validity of using the MLHFQ physical, emotional and total scores in patients with HF, for clinical practice and research. In addition, they confirmed the existence of a third factor, and we recommend the use of Munyombwe's social factor.
Bilbao et al. (Wed,) studied this question.
