The Coronary Artery Disease Education Questionnaire (CADE-Q) is a validated specific tool used to assess the knowledge and educate coronary patients in cardiac rehabilitation on aspects related to coronary artery disease (CAD). The aim of this study is to translate, cross-culturally adapt and validate from Portuguese to English the Coronary Artery Disease Education Questionnaire (CADE-Q).
Two independent translations were performed by qualified translators. After back-translation, both versions were reviewed by a committee of experts. A final English version was tested in a pilot study. For the psychometric validation, the tool was administered to 200 Canadian coronary patients enrolled in cardiac rehabilitation (CR). The internal consistency was assessed using Cronbach's alpha, the test-retest reliability using intraclass correlation coefficient (ICC), and the construct validity through factor analysis. Criterion validity of CADE-Q was assessed with regard to patients' characteristics.
Eleven of 19 questions were modified and culturally adapted in the English version. Cronbach's alpha was 0.809 and ICC was 0.846. Factor analysis revealed five factors, all internally consistent and well defined by the items. Criterion validity was supported by significant differences in mean scores by family income (p = 0.02) and educational level (p < 0.001).
The English version of the CADE-Q was demonstrated to have adequate reliability and validity, supporting its use in further studies.
冠心病教育问卷（CADE-Q）是一种经过验证的特定工具，用于评估心脏病康复中心冠心病患者在与冠心病相关方面的知识和教育程度。本研究旨在将冠心病教育问卷（CADE-Q）从葡萄牙语翻译、跨文化适应并验证为英语。
由合格的翻译人员进行两次独立的翻译。在回译后，由专家委员会对两个版本进行了审查。最终的英文版本在试点研究中进行了测试。为了进行心理测量学验证，该工具被用于 200 名在心脏康复中心（CR）登记的加拿大冠心病患者。采用 Cronbach's alpha 评估内部一致性，采用组内相关系数（ICC）评估重测信度，采用因子分析评估结构有效性。通过与患者特征的相关性评估 CADE-Q 的标准有效性。
19 个问题中有 11 个在英语版本中进行了修改和文化适应。Cronbach's alpha 为 0.809，ICC 为 0.846。因子分析显示有五个因子，所有因子的内部一致性和项目定义都很好。标准有效性得到了家庭收入（p = 0.02）和教育程度（p < 0.001）差异的支持。
英语版 CADE-Q 具有足够的信度和有效性，支持其在进一步研究中的使用。
