A general linear latent trait model for continuous item responses is described. The special unidimensional case for continuous item responses is Joreskog's (1971) model of congeneric item responses. In the context of the unidimensional case model for continuous item responses the concepts of item and test information functions, specific objectivity, item bias, and reliability are discussed; also the application of the model to test construction is shown. Finally, the correspondence with latent trait theory for dichotomous item responses is discussed.
描述了一种用于连续项目反应的广义线性潜在特质模型。连续项目反应的特殊单维情况是 Joreskog（1971）的同类型项目反应模型。在连续项目反应的单维情况模型的背景下，讨论了项目和测试信息函数、特定客观性、项目偏差和可靠性的概念；还展示了该模型在测试构建中的应用。最后，讨论了与二项式项目反应的潜在特质理论的对应关系。
