Abstract

Background and Aims

The Minnesota Life with Heart Failure Questionnaire (MLHF-Q), a globally recognized instrument, is widely used to assess the quality of life in heart failure (HF) patients. This study, conducted in Iran, investigated the psychometric properties of the Persian version of the MLHF-Q and contributed to the global understanding of the quality of life assessment of HF patients.

Methods

In this methodological study, the MLHF-Q was meticulously translated from English to Persian using a rigorous forward-backward translation process. Subsequently, the Persian version was comprehensively assessed for content and face validity, structural validity (through exploratory and confirmatory factor analysis), reliability, and stability.

Results

Five hundred twenty-seven heart failure patients participated in the study, with a mean age of 57.9 years (SD = 13.54). Exploratory factor analysis validated a three-factor structure for the scale, and confirmatory factor analysis showed satisfactory model fit indices (RMSEA = 0.08, CFI = 0.92, TLI = 0.91, IFI = 0.93). The questionnaire had exceptional internal consistency and reliability, with a Cronbach's alpha coefficient of 0.97 and an intraclass correlation coefficient (ICC) of 0.98, instilling confidence in our results' robustness.

Conclusion

The questionnaire used to measure the quality of life of heart patients is very accurate and reliable. It can evaluate the quality of life of these patients in three main sections (researchers, doctors, and patients).

伊朗版明尼苏达心力衰竭患者问卷（MLHF-Q）的验证研究：一项横断面研究

背景与目的明尼苏达心力衰竭生活问卷（MLHF-Q）是一种全球公认的工具，被广泛用于评估心力衰竭（HF）患者的生活质量。这项在伊朗进行的研究调查了波斯语版MLHF-Q的心理测量特性，并有助于全球对心衰患者生活质量评估的理解。方法在本方法学研究中，采用严格的前后翻译过程，将MLHF-Q从英语翻译成波斯语。随后，对波斯语版本进行内容效度、面效度、结构效度（通过探索性和验证性因素分析）、信度和稳定性的综合评估。结果527例心力衰竭患者参与研究，平均年龄57.9岁（SD = 13.54）。探索性因子分析验证了量表的三因子结构，验证性因子分析显示模型拟合指标令人满意（RMSEA = 0.08, CFI = 0.92, TLI = 0.91, IFI = 0.93）。问卷具有优异的内部一致性和信度，Cronbach's alpha系数为0.97，class内相关系数（ICC）为0.98，为我们的结果的稳健性提供了信心。结论该问卷用于测量心脏病患者的生活质量是准确可靠的。它可以从三个主要部分（研究人员、医生和患者）来评估这些患者的生活质量。
