The objective of this study was to develop a content valid, understandable, readable, and reliable Chronic Obstructive Pulmonary Disease knowledge Questionnaire (COPD-Q).
Twenty-one questions were generated as potential items to include in the COPD-Q. Twenty-two content experts provided both qualitative and quantitative assessments of two COPD-Q drafts. Ten patient volunteers completed a field test to assess clarity of individual COPD-Q items. An additional 24 patient volunteers completed a pilot test to determine internal consistency and test-retest reliability of the COPD-Q. The Flesch Reading Ease (FRE) was used to assess reading grade level of the COPD-Q.
Thirteen items were rated as "essential" (content validity ratio= p <0.05) by content experts and composed the final COPD-Q. Internal consistency, using Cronbach's alpha, was 0.72. Test-retest reliability, using intraclass correlation coefficient, was 0.90. The FRE score of the COPD-Q was 74.7 (equivalent to a 5th grade reading level).
The COPD-Q is a valid, readable and reliable knowledge assessment instrument for assessing COPD knowledge in patients who may have low health literacy skills.
Health care providers can use the COPD-Q to tailor counseling efforts according to individual patient needs, and to assess the effectiveness of their educational interventions.
本研究旨在开发一种内容有效、易懂、易读且可靠的慢性阻塞性肺疾病知识问卷（COPD-Q）。
生成了 21 个问题作为潜在的 COPD-Q 条目。22 位内容专家对 COPD-Q 的两个草案进行了定性和定量评估。10 名患者志愿者完成了现场测试，以评估单个 COPD-Q 条目的清晰度。另外 24 名患者志愿者完成了预测试，以确定 COPD-Q 的内部一致性和重测信度。Flesch 阅读容易度（FRE）用于评估 COPD-Q 的阅读年级水平。
13 项被内容专家评为“必要”（内容有效性比= p <0.05），构成了最终的 COPD-Q。使用 Cronbach's alpha 的内部一致性为 0.72。使用组内相关系数的重测信度为 0.90。COPD-Q 的 FRE 评分为 74.7（相当于 5 年级阅读水平）。
COPD-Q 是一种有效的、易读的和可靠的知识评估工具，可用于评估可能健康素养较低的患者的 COPD 知识。
医疗保健提供者可以使用 COPD-Q 根据患者的个体需求调整咨询工作，并评估其教育干预措施的效果。
