Item response theory (IRT), item banking and computer adaptive testing (CAT) methods have the potential to provide novel platforms for the collection, analysis and dissemination of patient data on health status and well-being. There are considerable challenges associated with building and maintaining a national item bank and it is uncertain whether there is sufficient interest among key stakeholders for IRT-based and CAT measures. The most convincing activity is demonstrating that the approach is feasible, psychometrically sound and useful in different specific applications. Demonstrated success opens up the possibility of more widespread acceptability and application. As part of the development effort, there needs to be continued meetings and discussion with psychometricians, instrument developers, clinical researchers, the FDA, pharmaceutical industry researchers and a managed care organizations about the advantages and disadvantages of a national item bank.
项目反应理论（IRT）、题库建设和计算机自适应测试（CAT）方法有潜力为收集、分析和传播关于健康状况和幸福感的患者数据提供新的平台。建立和维护一个国家级题库存在诸多挑战，而且关键利益相关者对基于IRT和CAT的测量方法是否有足够兴趣尚不确定。最有说服力的做法是证明该方法在不同的具体应用中是可行的、心理测量学上合理的且有用的。已证明的成功为更广泛的接受和应用开辟了可能性。作为开发工作的一部分，需要持续与心理测量学家、仪器开发者、临床研究人员、美国食品药品监督管理局（FDA）、制药行业研究人员以及管理式医疗组织就国家级题库的优缺点进行会议和讨论。
