This paper describes a paper and pencil questionnaire that measures heart disease risk knowledge in people with diabetes. The Heart Disease Fact Questionnaire (HDFQ) is a 25-item questionnaire that was developed to tap into respondents' knowledge of major risk factors for the development of CHD. Approximately half of these items specifically address diabetes-related CHD risk factors. Based on extensive pilot data, the current study analyzed responses from 524 people with diabetes to assess the psychometric properties. The HDFQ is readable to an average 13-year old and imposes little burden. It shows good content and face validity. It demonstrates adequate internal consistency, with Kuder-Richardson-20 formula = 0.77 and good item-total correlations. Item analysis showed a desirable range in P-values. In discriminant function analyses, HDFQ scores differentiated respondents by knowledge of their own cardiovascular health, use of lipid lowering medications, health insurance status, and educational attainment, thus indicating good criterion related validity. This measure of heart disease risk knowledge is brief, understandable to respondents, and easy to administer and score. Its potential for use in research and practice is discussed. Future research should establish norms as well as investigate its test-retest reliability and predictive validity.
本文介绍了一种用于测量糖尿病患者心脏病风险知识的纸笔问卷。心脏病事实问卷（HDFQ）是一份包含25个条目的问卷，旨在了解受访者对冠心病发生主要危险因素的知识。其中约一半的条目专门涉及与糖尿病相关的冠心病危险因素。基于大量的预试验数据，本研究分析了524名糖尿病患者的回答，以评估其心理测量学特性。HDFQ对于平均13岁的人来说易于阅读，负担很小。它具有良好的内容效度和表面效度。它显示出足够的内部一致性，库德-理查森公式20值为0.77，且各条目与总分的相关性良好。条目分析显示P值范围理想。在判别函数分析中，HDFQ得分根据受访者对自身心血管健康的了解、降脂药物的使用、健康保险状况和教育程度对受访者进行了区分，从而表明其具有良好的效标关联效度。这种心脏病风险知识测量方法简短，受访者易于理解，易于实施和评分。文中讨论了其在研究和实践中的应用潜力。未来的研究应建立常模，并调查其重测信度和预测效度。
