摘要
阐释了运用多组均数与协方差结构(MACS)模型侦查多级反应项目的一致性与非一致性项目功能差异(DIF)的原理与程序,以道德自我概念量表DIF的侦查进行示例,并对该方法进行了评价。与项目反应理论比照,MACS采用系统的、迭代的方式利用修正指数来侦查DIF,并提供多个拟合指数协同评价模型拟合;与标准验证性因素分析相较,MACS不仅能侦查非一致性DIF,而且能侦查一致性DIF。运用MACS侦查DIF是一种值得推荐的方法。
The article clarifies the principle and procedure of detection of uniform and non-uniform differentlal item functioning （DIF） on polytomous ordered response item using multiple-group mean and covariance structure analysis （MACS） model, gives a demonstration that how the procedure is applied to moral serf-concept scale for detection of DIF, and evaluates the method. Compared with item response theory, MACS concerns the systematic and iterative use of modification indices to detect DIF and gives multiple fit indices to assess model fit jointly. And compared with the standard confirmatory factor analysis, MACS allows the detection of not only non-uniform DIF but also uniform DIF. it is recommendable to detect DIF using MACS.
