目的探索合理、准确、高效的医学影像学考试命题模式.方法采用SPSS 13.0统计软件,对西安交通大学医学院第二附属医院2005级七年制学生的医学影像学试卷进行平均分、标准差和成绩分布状态以及试题难度、区分度、信度和效度的综合分析.结果共计67份试卷,成绩符合正态分布,平均分73.76,标准差11.88.试卷总体难度系数、信度和效度分别为0.74、0.78和0.25.主观性试题的难度系数、区分度、信度和效度均高于客观性试题(0.76 vs.0.73,0.94 vs.0.90,0.71 vs.0.68,0.32 vs.0.22).结论在医学影像学考试命题中,应保持相当比例的主观性试题,并制定详细的评分标准.以选择题为主的客观性试题作为补充,能够弥补主观性试题知识点覆盖面不全的缺点.

Objective To explore a reasonable,accuracy and effectual proposition model for medical imaging examination.Methods Mean scores and their standard deviation and distribution as well as the difficulty,discrimination,reliability and validity of the test paper were analyzed for the 2005 grade 7-year program students by using SPSS 13.0 statistic software.Results The scores of the 67 copies of test paper displayed a normal distribution,with the mean score of 73.76 and standard deviation of 11.88.The difficulty,reliability and validity indexes of the test paper were 0.74,0.78 and 0.25 respectively.The difficulty,discrimination,reliability and validity indexes of subjective items were higher than those of objective items(0.76 vs.0.73,0.94 vs.0.90,0.71 vs.0.68,0.32 vs.0.22,respectively).Conclusions We should keep quite high proportion of subjective items and make detailed scoring standard in medical imaging examination.Furthermore,as a supplement,objectively items such as multiple choice questions can expand the scope of knowledge examined.
