OBJECTIVE
Coronary heart disease (CHD) is a common and frequent disease with a long and incurable course, and the quality of life of patients is severely reduced. This study was to develop and validate a quality of life scale for patients with CHD based on the Chinese context.
METHODS
The scale QLICD-CHD (V2.0) was developed based on the QLICD-CHD (V1.0), using a programmed decision procedures. Based on the data measuring QoL 3 times before and after treatments from 189 patients with CHD, the psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness employing correlation analysis, multi-trait scaling analysis, structural equation modeling, t-test and also G-study and D-study of generalizability theory analysis. The SF-36 scale was used as the criterion to evaluate the criterion-related validity. Paired t tests were conducted to evaluate the responsiveness on each domain/facet as well as the total of the scale, with Standardized Response Mean (SRM) being calculated.
RESULTS
The QLICD-CHD (V2.0) has been developed with 42 items in 4 domains. The Cronbach's α of the general module, the specific module and the total scale were 0.91, 0.92 and 0.91 respectively. The overall score and the test-retest reliability coefficients in all domains are higher than 0.60, except for the specific module. Correlation and factor analysis confirmed good construct validity and criterion-related validity. After treatments, the overall score and score of all domains have statistically significant changes (P<0.01). The SRM of domain-level score ranges from 0.27 to 0.50. Generalizability Theory further confirm the reliability of the scale through more accurate variance component studies.
CONCLUSION
The QLICD-CHD (V2.0) could be used as a useful instrument in assessing QoL for patients with CHD, with good psychometric properties.
目的
冠心病（CHD）是一种常见且病程长、难以治愈的疾病，患者的生活质量严重下降。本研究旨在基于中国背景开发并验证冠心病患者生活质量量表。
方法
在QLICD-CHD（V1.0）的基础上，采用程序化决策程序开发了量表QLICD-CHD（V2.0）。基于189例冠心病患者治疗前后3次生活质量测量数据，运用相关分析、多特质量表分析、结构方程模型、t检验以及概化理论分析中的G研究和D研究，对量表的信效度和反应度进行评估。以SF-36量表作为标准来评估效标关联效度。进行配对t检验以评估量表各领域/方面以及总量表的反应度，并计算标准化反应均值（SRM）。
结果
QLICD-CHD（V2.0）已开发完成，包含4个领域的42个条目。一般模块、特异模块和总量表的Cronbach's α系数分别为0.91、0.92和0.91。除特异模块外，所有领域的总分及重测信度系数均高于0.60。相关分析和因子分析证实了良好的结构效度和效标关联效度。治疗后，总分及各领域得分均有统计学显著变化（P<0.01）。领域水平得分的SRM范围为0.27至0.50。概化理论通过更精确的方差成分研究进一步证实了量表的信度。
结论
QLICD-CHD（V2.0）可作为评估冠心病患者生活质量的有效工具，具有良好的心理测量学特性。
