Modified essay questions (MEQs) have been developed at the University of Newcastle to assess clinical problem-solving by first- and second-year medical students. Reliability estimates (given as coefficient alpha [60]) as high as 0.91 were reported for term assessment in 1979 based on MEQs. Lower estimates can be expected as statistical artifacts due to the faculty's criterion-referenced assessment of competence. More appropriate measures of reliability are currently being evaluated. The validity of assessment by MEQ was based on one model of medical problem-solving and another of cognitive skill taxonomies. Internal consistency estimates (coefficient alpha) based on each model yielded some interesting anomalies on the nature of problem-solving which may be reexamined in terms of cognitive preference indexes.
纽卡斯尔大学开发了改良短文问题（MEQs），用于评估医学专业一、二年级学生的临床问题解决能力。1979年基于MEQs进行的学期评估报告显示，可靠性估计值（以阿尔法系数[60]表示）高达0.91。由于教师对能力的标准参照评估，预计会有较低的估计值作为统计假象。目前正在评估更合适的可靠性测量方法。MEQ评估的有效性基于一种医学问题解决模型和另一种认知技能分类法。基于每个模型的内部一致性估计值（阿尔法系数）在问题解决的性质上产生了一些有趣的异常情况，这些情况可能会根据认知偏好指标进行重新审视。
