Assessing the health related quality of life (HRQOL) in patients with a disease specific scale is essential. The purpose of this study was to develop the Japanese version of the coronary revascularisation outcome questionnaire (CROQ), a disease-specific scale to measure HRQOL before and after coronary revascularisation.
The English version of the questionnaire was translated into Japanese; some terms were revised, and some items were eliminated to suit the Japanese medical environment. Eight patients filled out the questionnaire, which was then analyzed for face validity. In the field study, subjects were recruited from a university hospital in Tokyo, and questionnaires were given to fill out. In terms of statistical analysis, factor analysis, internal consistency, known-groups validity, concurrent validity with using Short-Form36 (SF-36) and Seattle Angina Questionnaire-Japanese version (SAQ-J), and test-retest reliability were assessed.
Informed consents were obtained from 356 patients, and out of 325 patients responded in the field study (91.3%). The factor structure of CROQ-Japanese version (CROQ-J) was similar to that of the original version. Cronbach's α ranged from 0.78 to 0.92. The concurrent validity was mostly supported by the pattern of association between CROQ-J, SAQ-J, and SF-36. Patients without chest symptoms had significantly higher scores of CROQ-J than those with chest symptoms. On the basis of analysis of the test-retest reliability, intra-class correlation coefficients were close to 0.70.
The Japanese translation of CROQ is a valid and reliable scale for assessing the patient's HRQOL in CAD.
使用特定疾病量表评估与健康相关的生活质量（HRQOL）至关重要。本研究旨在开发冠状动脉血运重建结局问卷（CROQ）的日文版，这是一种用于测量冠状动脉血运重建前后 HRQOL 的疾病特异性量表。
将问卷的英文版翻译成日文版；对一些术语进行修订，并删除一些项目以适应日本的医疗环境。有 8 名患者填写了问卷，然后对其进行了表面效度分析。在现场研究中，从东京的一所大学医院招募了受试者，并发放问卷进行填写。在统计分析方面，评估了因子分析、内部一致性、已知组有效性、与使用简短形式 36 项健康调查量表（SF-36）和西雅图心绞痛问卷-日本版（SAQ-J）的同时有效性以及测试-重测信度。
从 356 名患者中获得了知情同意，在现场研究中有 325 名患者（91.3%）做出了回应。CROQ-J 日本版（CROQ-J）的因子结构与原始版本相似。CROQ-J 的 Cronbach's α 范围为 0.78 至 0.92。同时有效性主要通过 CROQ-J、SAQ-J 和 SF-36 之间的关联模式得到支持。无胸痛症状的患者的 CROQ-J 评分明显高于有胸痛症状的患者。基于测试-重测信度分析，组内相关系数接近 0.70。
CROQ 的日文翻译是一种评估 CAD 患者 HRQOL 的有效且可靠的量表。
