To develop a questionnaire for measuring patients' knowledge about arthritis and its self-management.
An initial item pool of 175 multiple-choice questions was developed, based on the Stanford Arthritis Self-Management Program and on basic medical knowledge about arthritis and its management. A rheumatologist, psychologist, physiotherapist, and several lay individuals assessed the questions for content validity, breadth of coverage, and face validity. Patients assessed the questions for comprehensibility. Four subject groups with varying knowledge levels were recruited to answer the entire set of questions. Item analysis was undertaken to develop parallel forms of subtests so that repeated assessments could be undertaken.
The final instrument, the Arthritis Knowledge Questionnaire, consists of 2 tests, each comprising 3 subtests: self-management (15 items), arthritis in general (15 items), and rheumatoid arthritis (11 items).
We present psychometric evidence that these parallel forms provide highly reliable and valid estimates of knowledge concerning arthritis and arthritis self-management.
编制一份用于衡量患者对关节炎及其自我管理知识掌握情况的问卷。
基于斯坦福关节炎自我管理项目以及有关关节炎及其管理的基础医学知识，编制了一个包含175道多项选择题的初始题库。一名风湿病学家、一名心理学家、一名物理治疗师以及几位非专业人士对这些问题进行了内容效度、覆盖广度和表面效度评估。患者对问题的可理解性进行了评估。招募了四个知识水平各异的受试者组来回答整套问题。进行项目分析以编制平行形式的子测验，以便能够进行重复评估。
最终工具《关节炎知识问卷》由2个测试组成，每个测试包含3个子测验：自我管理（15项）、一般关节炎（15项）和类风湿关节炎（11项）。
我们提供了心理测量学证据，表明这些平行形式能够高度可靠且有效地评估有关关节炎及关节炎自我管理的知识。
