People with ischemic heart disease have increased drastically, and their health-related quality of life (HRQOL) has been increasingly important. The Coronary Revascularization Outcome Questionnaire (CROQ) is a widely used tool to assess the quality of life in patients with coronary artery disease. The purpose of this study was to rigorously examine the psychometric properties of the CROQ in patients who had undergone percutaneous coronary intervention (PCI).
The CROQ was translated into Korean. A total of 209 patients before PCI and 169 patients after PCI were recruited from a university hospital in Korea and completed questionnaires. In terms of statistical analyses, internal consistency, concurrent validity with using the Short Form 12 (SF-12) and Seattle Angina Questionnaire-Korean version (SAQ-K), and construct validity using exploratory factor analysis were assessed. Effective size statistics were calculated.
The internal consistency coefficients for all subscales of the CROQ were above 0.70, except the domain of adverse effects. The concurrent validity was mostly supported by the pattern of association among CROQ-K, SAQ-K, and SF-12. The results of EFA showed the core items of the CROQ had 7 factors. Large effect sizes were observed for the symptoms and the psychosocial functioning scales.
The Korean version of the CROQ is a valid and reliable scale for assessing HRQOL in patients with coronary artery disease.
缺血性心脏病患者数量急剧增加，其健康相关生活质量（HRQOL）愈发重要。冠状动脉血运重建结果问卷（CROQ）是评估冠心病患者生活质量的常用工具。本研究旨在严格检验CROQ在接受经皮冠状动脉介入治疗（PCI）患者中的心理测量特性。
将CROQ翻译成韩语。从韩国一家大学医院招募了209例PCI术前患者和169例PCI术后患者，并完成问卷调查。在统计分析方面，评估了内部一致性、与简短健康调查问卷12项版本（SF - 12）和韩国版西雅图心绞痛问卷（SAQ - K）的同时效度，以及使用探索性因素分析的结构效度。计算了效应量统计值。
CROQ所有子量表的内部一致性系数均高于0.70，但不良反应领域除外。CROQ - K、SAQ - K和SF - 12之间的关联模式大多支持同时效度。探索性因素分析结果显示CROQ的核心项目有7个因素。在症状和心理社会功能量表上观察到较大的效应量。
韩语版CROQ是评估冠心病患者HRQOL的有效且可靠的量表。
