基于项目反应理论的老年医学知信行量表条目分析与评价
|
摘要
目的用项目反映理论对老年医学知信行量表进行条目分析与评价。方法选取北京协和医学院临床八年制医学本科生及护理本科生。用双参数logistic模型分析知识维度条目,用等级反应模型分析态度维度和行为维度条目,计算各条目区分度、难度和信息量并绘制项目特征曲线,评估条目的质量。结果老年医学知信行量表最大信息量为18.810,最大信息量所对应的潜在能力参数值为-0.4;34个条目中,23个条目性能良好,11个条目因难度和区分度超出标准范围有待修订。结论老年医学知信行量表的大部分条目性能良好,但部分条目需进一步修订并验证效果。
Objective To analyze and evaluate the items of geriatric knowledge, attitude and practice scale by using item response theory. Methods The subjects were selected from eight-year medical undergraduates and nursing undergraduates of Peking Union Medical College. Two-parameter logistic model was used to analyze items of knowledge dimension, and grade response model was used to analyze items of attitude and practice dimensions. The degree of discrimination, difficulty and information of each item were calculated, and the item characteristic curve was drawn to evaluate the quality of items. Results The maximum information function of the scale was 18.810, and the potential ability parameter corresponding to the maximum information function was-0.4. Of the 34 items, 23 items performed well, and 11 items were out of the standard framework due to difficulty or discrimination parameters.Conclusions Most items of the geriatric knowledge, attitude and practice scale have good performance, but some items need to be further revised and validated.
