背景资料：明尼苏达心力衰竭生活质量问卷（MLHFQ）是心力衰竭（HF）患者最广泛使用的健康相关生活质量问卷之一。它提供了两个维度的分数，身体和情感，以及总分。然而，对其因素结构存在一些关切，并提出了替代办法，其中一些办法包括代表社会层面的第三个因素。本研究的目的是分析MLHFQ的内部结构和总得分的单维度，并比较不同的因素结构proposed.Methods：MLHFQ被给予2565例HF患者。采用验证性因素分析（CFA）和Rasch分析评价问卷的结构效度。这两种方法也适用于替代structures proposed.Results：CFA结果的假设模型的两个潜在的因素和Rasch分析证实了适当的身体和情绪量表。Rasch对总分的分析显示只有两个问题。对其他双因子结构的验证性分析结果并不比原结构的结果好。应用于不同的社会因素的Rasch分析产生了最好的结果Munyombwe的社会层面，由6 items.Conclusions组成：我们的研究结果支持使用MLHFQ的身体，情感和总分数在HF患者的有效性，为临床实践和研究。此外，他们证实了第三个因素的存在，我们建议使用Munyombwe的社会因素。
Background: The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is one of the most widely used health-related quality of life questionnaires for patients with heart failure (HF). It provides scores for two dimensions, physical and emotional, and a total score. However, there are some concerns about its factor structure and alternatives have been proposed, some including a third factor representing a social dimension. The objectives of the present study were to analyze the internal structure of the MLHFQ and the unidimensionality of the total score, and to compare the different factor structures proposed.Methods: The MLHFQ was given to 2565 patients with HF. The structural validity of the questionnaire was assessed by confirmatory factor analysis (CFA), and Rasch analysis. These two approaches were also applied to the alternative structures proposed.Results: The CFA results for the hypothesized model of two latent factors and the Rasch analysis confirmed the adequacy of the physical and emotional scales. Rasch analysis for the total score showed only two problematic items. The results of the CFA for other two-factor structures proposed were not better than the results for the original structure. The Rasch analyses applied to the different social factors yielded the best results for Munyombwe's social dimension, composed of six items.Conclusions: 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.
