Health-related quality of life has emerged as an important outcome in treating and managing patients with heart failure (HF). However, there is no existing instrument for use in Chinese populations.
To translate the Minnesota Living With Heart Failure Questionnaire (MLHFQ) into a Chinese version and to validate it in the clinical setting.
This was a cross-sectional study. A convenience sample of 247 participants with New York Heart Association Class II to III chronic HF were recruited from a cardiovascular outpatient department in Taiwan.
The content validity index was 0.98. Construct validity was supported by exploratory factor analysis, which showed three factors with 20 of 21 items loading above .50, explaining 71% of the variance. Total scale and subscale scores were correlated highly with the reference instruments, indicating satisfactory concurrent and convergent validity. The mean scores of the Chinese version of the MLHFQ were significantly higher among participants with HF than those from a non-HF comparison group. The instrument demonstrated high internal consistency (Cronbach's alpha of .95 for the scale and .93 to .95 for the subscales).
The psychometric properties indicate that the Chinese version of the MLHFQ is a valid and reliable instrument for future research. This instrument provides a holistic approach for measuring health-related quality of life in New York Heart Association Class II and III HF patients.
与健康相关的生活质量已成为治疗和管理心力衰竭（HF）患者的一项重要结果指标。然而，目前尚无适用于中国人群的工具。
将明尼苏达心力衰竭生活问卷（MLHFQ）翻译成中文版，并在临床环境中进行验证。
这是一项横断面研究。从台湾一家心血管门诊招募了247名纽约心脏协会II至III级慢性HF患者作为便利样本。
内容效度指数为0.98。探索性因子分析支持结构效度，结果显示三个因子，21个条目中有20个条目的载荷高于0.50，解释了71%的方差。总量表和分量表得分与参考工具高度相关，表明具有令人满意的同时效度和收敛效度。MLHFQ中文版的平均得分在HF患者中显著高于非HF对照组。该工具显示出较高的内部一致性（总量表的Cronbach's α为0.95，分量表的Cronbach's α为0.93至0.95）。
心理测量学特性表明，MLHFQ中文版是未来研究中一种有效且可靠的工具。该工具为测量纽约心脏协会II级和III级HF患者与健康相关的生活质量提供了一种全面的方法。
