摘要：

通常把测验中共用同一刺激的项目集合称为题组, 并把由共同刺激引起的题组项目反应间的相依性称为题组效应。本文首先分别对题组、局部独立性和局部依赖性的概念进行了介绍和梳理, 并结合前人研究给出了题组效应的概念。之后在阐明直接使用标准项目反应模型去拟合题组反应数据会导致参数估计偏差等诸多问题后, 引出能更好地处理题组效应的题组反应模型。全文详细介绍了包括高阶题组模型和多水平题组模型在内的6种题组反应模型, 通过对“如何理解题组反应模型中的区分度参数”和“题组反应模型与多维项目反应模型的关系”两问题的探讨, 认为：(1)题组反应模型与标准项目反应模型中的区分度参数含义并不相同, 直接将两者进行对比是不合理的; (2)题组反应模型属于广义多维项目反应模型, 与狭义多维项目反应模型的主要区别在于满足广义局部独立性假设时所需要控制的潜因素不同。

Abstract:

A testlet is a cluster of items that share a common passage, stimulus, or other context, and the dependence between testlet-based item responses that caused by the common stimulus called testlet effect. This article introduced and combed the concepts of testlet, local independence and local dependence, and proposed the concepts of testlet effect in accordance with previous research. Applying standard item response models to testlet responses leaded to many problems such as biased parameter estimation and overestimation of test reliability, hence, testlet response model was introduced to deal with testlet effect better. 6 testlet response models were described in detail including Higher-order testlet model and Multilevel testlet model, and two issues were discussed: (a) the connotation of slope parameter in testlet response model is different from that in standard item response theory which is inappropriate to contrast the two directly; (b) testlet response model belongs to general multidimensional item response model and the main distinction with special multidimensional item response model is the latent factors needed to control to satisfy general local dependence hypothesis.

Key words: testlet response theory, testlet response model, multidimensional item response theory, general multidimensional item response model, general local independence
