摘要：

题目参数漂移(Item Parameter Drift, IPD)指锚题参数值在若干连续性测试场合或测验水平之间的变化。该概念和项目功能差异(Differential Item Function, DIF)有实质区别。当前的IPD研究涵盖五个方面：IPD的实际存在、产生原因、检测方法、链接结果效应, 及极端锚题的处理策略。横向IPD领域需要更进一步和具有综合性的研究, 尤其需研究DIF检测方法在IPD检测中的语境适用性, 开发针对IPD的检测方法, 以及发展修正的链接程序。纵向IPD研究需要进行系统、深入探索。

Abstract:

Item Parameter Drift (IPD) refers to change in parameter value (s) of the anchor item across several sequential testing occasions or test levels. This concept is essentially different from the concept of Differential Item Functioning (DIF). Current research on IPD spans five aspects: the practical existence, reasons, detection methods, and linking effects of IPD, and the strategy to the outlier anchor item. With respect to horizontal IPD, further and more comprehensive research is needed; esp., we should study the contextual applicability of DIF detection methods in the detection of IPD and develop detection methods for IPD specially, and develop revised linking procedures. Systematic and deep investigations are called up on vertical IPD.

Key words: test linking, parameter invariance, item parameter drift, differential item functioning, nonequivalent groups with anchor test design.
