Patients' knowledge concerning high blood pressure (HBP) is a useful outcome measure in HBP education programs. However, valid and easy-to-use HBP knowledge assessment tools are scarce. The purpose of the study was to validate the HBP Knowledge Test (HKT) in two independent samples of Korean Americans with HBP (N=885). A total of 61% of the sample were women with a mean age of about 61 years (standard deviation=11.0) and 44% reported some college education or greater. Psychometric and item response theory analyses identified 21 items that fit a unidimensional model to form the HKT. Internal consistency was acceptable, with Cronbach's α=0.70. Construct validity testing revealed that patients with controlled BP had significantly higher HKT scores than those with uncontrolled BP (P=.012). The HKT is a simple questionnaire for assessing and monitoring HBP knowledge. It is sensitive to differences in blood pressure control status and should provide a valid, reliable, and standardized measure of HBP knowledge with wide relevance.
患者对高血压（HBP）的了解是 HBP 教育计划中有用的结果衡量标准。然而，有效的、易于使用的 HBP 知识评估工具却很匮乏。本研究的目的是在两个独立的有 HBP 的韩裔美国人样本中验证 HBP 知识测试（HKT）（N=885）。样本中共有 61%为女性，平均年龄约为 61 岁（标准差=11.0），44%的人报告接受过一些大学教育或更高教育。心理测量学和项目反应理论分析确定了 21 个符合单维模型的项目，形成了 HKT。内部一致性可接受，克朗巴赫的α=0.70。结构有效性测试表明，血压控制良好的患者的 HKT 得分明显高于血压控制不佳的患者（P=.012）。HKT 是一种用于评估和监测 HBP 知识的简单问卷。它对血压控制状况的差异敏感，应该为 HBP 知识提供一种有效、可靠和标准化的衡量标准，具有广泛的相关性。
