经典测试理论（CTT）包括一组概念和方法，为目前健康研究中使用的许多测量工具提供了基础。讨论了CTT背后的假设和概念。这些包括项目和规模的特点，来自CTT以及类型的可靠性和有效性。总结了CTT下量表开发中常用的程序，包括因素分析和量表评分的创建。CTT的优点和缺点，它的使用跨人群，并继续使用在面对最近的测量模型进行了讨论。
Classical test theory (CTT) comprises a set of concepts and methods that provide a basis for many of the measurement tools currently used in health research. The assumptions and concepts underlying CTT are discussed. These include item and scale characteristics that derive from CTT as well as types of reliability and validity. Procedures commonly used in the development of scales under CTT are summarized, including factor analysis and the creation of scale scores. The advantages and disadvantages of CTT, its use across populations, and its continued use in the face of more recent measurement models are also discussed.
