摘　　要：本文对多级计分认知诊断测验的DIF概念进行了界定,并通过模拟实验以及实证研究对四种常见的多级计分DIF检验方法的适用性进行理论以及实践性的探索。研究结果表明:四种方法均能对多级计分认知诊断中的DIF进行有效的检验,且各方法的表现受模型的影响不大;相较于以总分为匹配变量,以KS为匹配变量时更利于DIF的检测;以KS为匹配变量的LDFA方法以及以KS为匹配变量的曼特尔检验方法在检测DIF题目时有着最高的检验力。Currently,polytomous cognitive diagnosis test has attracted more and more researchers’ attention because it combines the advantages of polytomous items that can provide researchers with more information and the characteristics of cognitive diagnostic tests that can reflect the participants’ inherent knowledge structure.However,some basic problems such as differential item functioning(DIF) have not been solved,which greatly limit the practical application of the polytomous cognitive diagnosis test.Therefore,the main purpose of this study is to introduce several commonly used polytomous DIF detection procedures into polytomous cognitive diagnostic test to fill the gaps in this field.Firstly,the concept of DIF in the field of polytomous cognitive diagnosis test was defined and four DIF detection procedures include the mantel test,the logistic discriminant function analysis(LDFA),the likelihood ratio test(LR test),and Wald test were extended to polytomous cognitive diagnosis.Then simulation experiment was explored to investigate the performance of these polytomous DIF detection procedures in indetecting the uniform DIF under the estimation of four reduced models of seq-DINA,seq-DINO,seq-ACDM,seq-RRUM and a saturation model of seq-GDINA.In addition to the differences in the estimation model,some independent variables also included in the simulation experiment such as the DIF size,sample size,matching variables,and the proportion of DIF items.Two levels of DIF size were.05 and.1.Two levels of sample size were 500 and 1000 examinees per group.Two levels of matching variables mainly for LDFA and the mantel test method were with KS as the matching variable and with the total score as the matching variable.Three levels of the proportion of DIF items were 10%,20% and 30%.Finally,an empirical study was implemented to show the practical application of each method.The results are as follows:(1) Whether in the reduced model or the saturated model,all the DIF detection procedures can effectively detect the uniform DIF in the
