医学生信息素养标准化测评工具研制(二):测试题项

The Development of a Standard Measuring Tool for Medical Students’ Information Literacy(Two):Test Items

医学生信息素养测评理论框架包括信息意识、信息知识、信息能力、信息伦理与道德4个测量维度。通过专家咨询法评价测试题项的内容效度（题项的准确性、清晰度和适用性），对整个测试体系在数量上进行了删减，并对部分题项的内容作了更科学的处理。通过综合指数法建立了各测试题项的权重系数。应用因子分析方法对测评体系进行结构效度检验，共提取4个公因子，能够与之前建立的测评理论框架中确定的4个维度相一致。方差分析结果表明，医学生与临床医学八年制学生、卫管专业本科生的信息素养水平的差异在统计学上有显著意义（P〈0．05），区分效度良好，测评体系整体信度较高。效应尺度统计量（ES）分析结果表明，《医学文献检索与利用》课程干预后，医学生的信息素养整体以及各维度的水平均有显著性改善。最终形成的标准化测评工具能够用于医学生信息素养水平的测量。

The measuring theoretieal framework of Medical students＇ information literacy consists of four dimeosions; they am information awareness, information knowledge, information ability, and information ethics morals. After evaluating the test items validity （its accuracy, clarity and applicability） through expert consultation method, researchers cut the amount of the test system and scientific processing for particular items is done. They also build different weighting coefficients for each test item with comprehensive index method. Factor analysis method is being used to test the construct validity and four common factors arc put forward, which are in conformity with the four dimensions of the measuring theoretical frameworlc The variance analysis shows that the differences in the level of information literacy amongst medical students, eight-year clinical medical students and health management undergraduates are statistically significant （P〈0.05）, and have a good discriminant validity. The overall reliability of the evaluation system is relatively high and the effect scales show that after the intervention of taking Medical Literature Retrieval and Utilization, the information literacy of medical students achieve an overall improvements greatly as well as each dimension level. The final standard measuring tool turns out to be possibly used to measure the information literate level of medical students.
