【摘要】：测验等值,作为心理测量中的一个重要领域,其主要目的是使不同测验版本的分数之间具有可比性,为考试的公平性提供保障。此项研究以经典测验理论为等值模型,对2015年11月份和2015年5月份心理咨询师(三级)职业资格考试的试卷进行了等值分析,为国内相关的资格考试的等值研究与应用提供了理论与实践的参考价值。此项研究的等值方法选用锚测验非等组设计,以经典测验理论为等值理论模型,探究了锚测验非等组设计中的Tucker观察分数的方法、Levine观察分数的方法与Levine真分数的方法,对这三种线性等值方法做出了比较研究。通过比较这三种方法在不同总体权重下的等值误差的大小,选出等值误差最小的一个作为心理咨询师(三级)职业资格考试的等值方法。将最适合心理咨询师(三级)职业资格考试的等值方法的转换方程应用于两次测验成绩的等值中,经过严密的统计和分析得出2015年11月份与2015年5月份心理咨询师(三级)职业资格考试的等值转换分数对照表。研究结果表明选用的锚测验与2015年11月份和2015年5月份两次测验的相关系数分别为:0.888和0.855,锚测验与两份测验之间有显著的相关。在线性等值法中,当总体权重为1时,Tucker观察分数法的截距为-4.673,斜率为0.966;Levine观察分数法的截距为-5.850,斜率为0.961。当总体权重为0.501时,Tucker观察分数法的截距为-4.692,斜率为0.965;Levine观察分数法的截距为-5.930,斜率为0.963;Levine真分数法的截距为-7.153,斜率为0.985。选用加权误差均方差作为等值误差大小的指标,得出当总体权重为1时,Tucker观察分数法等值误差最小为1.6008;当总体权重为1时,Levine观察分数法等值误差最大为2.0687。据此可知,当总体权重为1时,Tucker观察分数法最适合作为心理咨询师(三级)职业资格考试的等值方法。根据总体权重为1时,Tucker观察分数法的等值方程y=0.966x-4.674,可以将2015年11月份心理咨询师(三级)职业资格考试理论部分与2015年5月份心理咨询师(三级)职业资格考试理论部分进行两个测验版本之间分数的等值转换,实现两份测验的等值。通过等值数据的分析,得到如下结论:1、在心理咨询师职业资格考试的等值实践中选用锚测验设计是比较科学的。2、在心理咨询师这类的职业资格考试中宜选用Tucker法来实现测验版本之间的等值。3、不同总体权重的选择,对实现心理咨询师职业资格考试的等值结果的影响甚微。
[Abstract]:As an important field of psychological measurement, the main purpose of test equivalence is to make the scores of different test versions comparable and to guarantee the fairness of the test. Using classical test theory as the equivalent model, this study analyzed the equivalence of the test papers of psychological counselors (level 3) vocational qualification examination in November 2015 and May 2015, respectively. It provides theoretical and practical reference value for the research and application of relevant qualification examination in China. The equivalence method of this study is based on the non-equal group design of anchor test. Based on the classical test theory as the equivalent theoretical model, the method of Tucker observation score and the method of Levine true score in the design of anchor test non-equal group are explored. The three linear equivalence methods are compared and studied. By comparing the magnitude of the equivalent errors of the three methods under different total weights, the one with the smallest equivalent error is selected as the equivalent method of the professional qualification examination of the counselors (level 3). The conversion equation of the equivalent method most suitable for the professional qualification examination of the counsellor (level 3) was applied to the equivalence of the results of the two tests. Through strict statistics and analysis, a comparison table of equivalent conversion scores between November 2015 and May 2015 was obtained. The results show that the correlation coefficients between the anchor test and the two tests in November 2015 and May 2015 are respectively 0: 0.888 and 0.855, and there is a significant correlation between the anchor test and the two tests. In the linear equivalent method, when the total weight is 1, the intercept of Tucker observation fraction method is -4.673, the slope is -5.850 and the slope is 0.961. When the total weight is 0.501, the intercept of Tucker observation fraction method is -4.692, the slope is -5.930, the slope is -7.153 and the slope is 0.985.The total weight of Tucker observation fraction method is -4.692, the slope is -5.930. The weighted error mean square error is chosen as the index of equivalent error, and the minimum equivalent error of Tucker observation fraction method is 1.6008 when the total weight is 1, and the maximum equivalent error of Levine observation fraction method is 2.0687 when the total weight is 1. Therefore, when the total weight is 1, the Tucker observation score method is the most suitable for the equivalent method of the professional qualification examination for psychological counsellors (level 3). According to the equivalent equation of the Tucker observation score method with a total weight of 1, 0.966x-4.674, the theoretical part of the professional qualification examination for psychological counselors (level 3) in November 2015 and the theory for the vocational qualification examination for psychological counselors (level 3) in May 2015 can be regarded as the theory of the vocational qualification examination for psychological counselors (level 3) in May 2015. Part of the equivalent conversion of scores between the two test versions, Achieve the equivalent of two tests. Through the analysis of equivalent data, The conclusion is as follows: 1, it is more scientific to choose anchor test design in the equivalent practice of the psychological counsellors' vocational qualification examination, and the Tucker method should be used in the psychological counsellors' professional qualification examination to realize the difference between the test versions. Equal value. 3, selection of different overall weights, It has little influence on the achievement of the equivalent result of the psychological counsellors' professional qualification examination.
