摘要： 目的: 通过分析国家某口腔医学统一考试试题难度预估方法的效果及其影响因素,研究改进预估方法的可能路径。方法: 对试题难度预估方法改进前、后预估值与实测值一致性进行对比分析,并对改进方法的可能影响因素进行评价。使用SPSS 16.0软件包对数据进行统计学分析。结果: 方法改进后,试题预估难度与实测难度的一致性提高;两者一致性的变化以分数中间组考生最为显著（P<0.05）,且受预估专家人数、题型及认知层次等多因素影响。结论: 通过改进试题难度预估方法,可有效改进预估效果,对提高组卷预测性,进而精准评价合格考生有所帮助。

Abstract: PURPOSE: To explore a possible method of improving prediction by analyzing the effect and influencial factors of difficulty prediction of a national board dental examinations. METHODS: The correlation between the predicted value and the measured value, and related influential factors were analyzed with SPSS 16.0 software package. RESULTS: The correlation between the predicted difficulty and the tested difficulty increased after the improvement of the method (P<0.05). The correlation was mainly reflected in the median score group of candidates. CONCLUSIONS: Improving the method of difficulty prediction can increase the prediction effect, and it is helpful to improve the forecasting ability of the test paper and to evaluate the candidates accurately.
