The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is commonly used to measure quality of life (QOL) in patients with heart failure (HF). We examined the psychometric properties and cultural validity of an Arabic version of the MLHFQ.
An observational cross-sectional study was conducted with 210 adult HF outpatients. Patients were interviewed with the Arabic MLHFQ and the Patient Health Questionnaire (PHQ-9). Cronbach's alpha coefficient and confirmatory factor analysis were conducted. Patients with different NYHA classes and HF-hospitalization histories were compared on QOL to test known-group validity.
The confirmatory factor analysis yielded 3 factors: physical, emotional, and social. Three items (4, 8, and 15) had low loadings. The overall Cronbach's alpha coefficient was 0.92. There were significant differences in MLHFQ by PHQ-9 categories, NYHA class, and HF-hospitalization history.
This Arabic version of MLHFQ is valid and reliable and can be used in Arabic-speaking Lebanese HF populations.
明尼苏达州心力衰竭生活质量问卷（MLHFQ）常用于评估心力衰竭（HF）患者的生活质量（QOL）。我们检验了阿拉伯语版 MLHFQ 的心理测量学特性和文化适宜性。
采用观察性横断面研究，纳入 210 例成年 HF 门诊患者。患者接受阿拉伯语版 MLHFQ 和患者健康问卷（PHQ-9）访谈。进行克朗巴赫 α 系数和验证性因子分析。比较不同 NYHA 分级和 HF 住院史患者的 QOL，以检验已知组别的有效性。
验证性因子分析得出 3 个因子：身体、情绪和社会。有 3 个项目（4、8 和 15）的负荷较低。MLHFQ 的总克朗巴赫 α 系数为 0.92。PHQ-9 类别、NYHA 分级和 HF 住院史与 MLHFQ 有显著差异。
阿拉伯语版 MLHFQ 具有有效性和可靠性，可用于阿拉伯语黎巴嫩 HF 人群。
