摘要:
 被试回答人格测验题目时并不是特质水平越高其得分率越高，这称为非累积反应 机制。广义等级展开模型GGUM就是针对这一机制提出来的。使用EPQ和五因素人格问卷发现G GUM比累积IRT模型有更好的模型拟合度和测量精度。研究结果表明GGUM有其合理性，且有助 于反应心理过程机制的深入探讨。
Abstract:
 People with high trait level will not necessarily get high scores w hen responding to non-cognitive items，this is called non-cumuˉlative response m echanism.Generalized Graded Unfolding Model（GGUM）is an IRT model developed to s olve this problem in personality.In this study EPQ and NEO-FFI were administered to991and1017students，the results show that GGUM can fit the data better and pr ovide more information than cumulative IRTmodels（2PLM and SGRM）.The study also suggests that the issues of model fit and response mechanism in personality sho uld be further studied.
