This study evaluated the psychometric properties of the Mandarin version of the HeartQoL questionnaire, a core ischemic heart disease (IHD) health-related quality of life (HRQL) instrument, in patients with angina, myocardial infarction (MI), and ischemic heart failure (IHF).
The English version of HeartQoL was translated into Mandarin. A cross-sectional study was then conducted in mainland China using the Mandarin HeartQoL, Short Form-12 Health Survey, and Hospital Anxiety and Depression Scale. Factor analysis was used to establish the HeartQoL structure and internal consistency reliability and construct validity were assessed.
Patients with IHD (n = 412; angina = 112, MI = 151, and IHF = 149) were enrolled. Significantly higher HeartQoL HRQL scores were reported by patients with either angina or MI than by patients with IHF. The 2-factor structure was confirmed by Mokken scale analysis in the total group with strong H coefficients on the global scale (0.64) and both the physical (0.70) and emotional (0.80) subscales. Internal consistency reliability was strong with Cronbach's α ranging from 0.90 to 0.95. Convergent validity was confirmed with strong correlations between similar physical and mental HeartQoL and Short Form-12 Health Survey subscales ranging from 0.77 to 0.82 with divergent validity confirmed with significantly lower correlations between dissimilar constructs. Discriminative validity was confirmed for 72% of the a priori sociodemographic and clinical hypotheses.
The Mandarin version of the HeartQoL HRQL questionnaire demonstrates acceptable internal consistency reliability and convergent, divergent, and discriminative validity in patients with IHD and in each diagnostic subgroup. The data support the use of the HeartQoL to assess and compare HRQL in Mandarin-speaking patients with IHD.
本研究评估了 HeartQoL 问卷简体中文版的心理测量特性，HeartQoL 是一种核心缺血性心脏病（IHD）健康相关生活质量（HRQL）工具，适用于心绞痛、心肌梗死（MI）和缺血性心力衰竭（IHF）患者。
将 HeartQoL 的英文版本翻译成中文。然后在中国内地进行了一项横断面研究，使用简体中文版 HeartQoL、简明健康状况调查问卷和医院焦虑抑郁量表。采用因子分析确定 HeartQoL 的结构，评估内部一致性信度和结构效度。
共纳入 412 例 IHD 患者（心绞痛 112 例、MI 151 例和 IHF 149 例）。有或没有 MI 的心绞痛患者报告的 HeartQoL HRQL 评分显著高于 IHF 患者。Mokken 量表分析在整个研究组中确认了 2 个因子结构，总量表的 H 系数为 0.64，生理和情感子量表的 H 系数分别为 0.70 和 0.80。内部一致性信度较高，Cronbach's α 范围为 0.90 至 0.95。相似的生理和心理 HeartQoL 与简明健康状况调查问卷子量表之间存在较强的相关性，范围为 0.77 至 0.82，证实了其具有良好的会聚效度，而不同结构之间的相关性较低，证实了其具有良好的区分效度。72%的先验社会人口学和临床假设得到了区分效度的验证。
简体中文版的 HeartQoL HRQL 问卷在 IHD 患者和每个诊断亚组中均表现出可接受的内部一致性信度、会聚、区分和区分效度。该数据支持使用 HeartQoL 来评估和比较讲汉语的 IHD 患者的 HRQL。
