背景：目前几乎没有测量骨质疏松症知识的工具，骨质疏松症是2800万美国人的健康风险。最初的骨质疏松症事实测验(FOOQ)从理论上讲是由Orem(1995)的自我护理理论提供的，于1998年出版。2000年，美国国立卫生研究院(NIH)召开了一次关于骨质疏松的共识会议。目的：根据最新的科学证据更新原始工具，并确定其心理测量学特性。方法：测验内容经骨质疏松专家验证，理论上依据Orem(2001)的自我护理理论。使用迭代过程来设计具有可接受读数水平的仪器。结果：修订后的测验内容基于2000年美国国立卫生研究院骨质疏松共识会议，包括20个问题。该测验的内容效度指数为0.87，内部一致性信度为0.76，阅读水平为6年级。结论：修订后的FOOQ具有较好的信度和效度，具有较好的心理测量学特征。
Background: Few instruments exist that measure knowledge of osteoporosis, a health risk for 28 million Americans. The original Facts on Osteoporosis Quiz (FOOQ), which was theoretically informed by Orem's (1995) Self-Care Theory, was published in 1998. In 2000, the National Institutes of Health (NIH) held a consensus conference on osteoporosis in which previous knowledge was modified based on current science.Objectives: The goal was to update the original instrument based on the latest scientific evidence and to determine its psychometric properties.Method: The quiz content was validated by osteoporosis experts and is theoretically informed by Orem's (2001) Self-Care Theory. An iterative process was used to design an instrument with an acceptable reading level. Reliability, item discrimination, and item difficulty were assessed in a convenience sample of 256 participants.Results: The revised quiz, content-based on the 2000 NIH osteoporosis consensus conference, includes 20 questions. The quiz has a content validity index of .87, an internal consistency reliability of .76 and a 6th grade reading level. Item difficulty and item discrimination are also reported.Conclusions: The revised version of the FOOQ provides a valid, reliable, and theoretically informed instrument with acceptable psychometric properties.
