摘　　要：变点分析法是目前在心理与教育测验中实用性非常高的侦测异常反应的手段,变点分析方法不仅能够识别被试在测验过程中是否存在异常作答反应,还能检测异常变点发生的具体位置。本研究首次将变点分析方法拓展到迫选测验中,并对变点分析法的各指标在迫选测验中的异常反应侦测效果进行了验证。结果表明,基于似然比检验的个人拟合统计量(L_(max))、基于加权残差的个人拟合统计量(R_(max))和基于Wald检验的个人拟合统计量(Wmax)在所有实验条件下,I-类错误率接近显著性水平(α=.05);在统计检验力方面,L_(max)的检测力高于另外两种指标;在变点定位绝对偏差方面,Wmax定位的变点位置相对来说最准确;潜在特质估计结果表明,通过变点分析方法对被试的异常作答数据进行清洗后,被试的潜在特质估计精度有了显著改善。总体来说,变点分析法的各指标在迫选测验中对后程随机作答的检测结果比较理想且三种方法的侦测结果具有高度一致性(κ>.61,p<.001)。Psychological tests mainly include cognitive tests and personality tests.In cognitive tests,participants can make a correct choice when they know the correct answer,regardless of the guessing factor.However,in personality tests,participants are free to improve their scores.Previous studies have shown that traditional personality tests are prone to acquiescence response,halo effect,impression management,and other abnormal responses.Many methods used to detect abnormal responses are only proposed for ability tests,but are lacking for personality tests.With the wide application of personality tests in the field of talent assessment,it becomes more urgent to detect whether there is an abnormal response in the test.The development of forced-choice questionnaires avoids the disadvantages of traditional personality tests to some extent.However,personality test is still affected by response style and random response,especially by back random response.Because the length of personality tests is long or the motivation of the participants is low,the participants are prone to random response in the latter part of the test(BRR).BRR is a common abnormal phenomenon in psychological tests.It can increase the error of potential trait estimation,which cannot reflect the real trait level of the participants.At the same time,it can seriously reduce the reliability and validity of the test.Change point analysis is a popular method for detecting abnormal responses in psychological tests.The advantage of CPA is that it can identify not only the abnormal response of a particular participant,but also detect the specific location of the change point(Shao,2016).Therefore,the CPA method can help researchers clean up the abnormal part of the data independently without deleting all the data of the participants during data analysis.In this way,the influence of abnormal response can be reduced,the valid data can be retained to the maximum extent and the accuracy of parameter estimation can be improved.On the basis of previous studies and in comb
