Graduate entry medicine raises new questions about the suitability of students with different backgrounds. We examine this, and the broader issue of effectiveness of selection and assessment procedures.
The data included background characteristics, academic record, interview score and performance in pre-clinical modular assessment for two years intake of graduate entry medical students. Exploratory factor analysis is a powerful method for reducing a large number of measures to a smaller group of underlying factors. It was used here to identify patterns within and between the selection and performance data.
Basic background characteristics were of little importance in predicting exam success. However, easily interpreted components were detected within variables comprising the 'selection' and 'assessment' criteria. Three selection components were identified ('Academic', 'GAMSAT', 'Interview') and four assessment components ('General Exam', 'Oncology', 'OSCE', 'Family Case Study'). There was a striking lack of relationships between most selection and performance factors. Only 'General Exam' and 'Academic' showed a correlation (Pearson's r = 0.55, p<0.001).
This study raises questions about methods of student selection and their effectiveness in predicting performance and assessing suitability for a medical career. Admissions tests and most exams only confirmed previous academic achievement, while interview scores were not correlated with any consequent assessment.
研究生入学医学提出了关于具有不同背景的学生是否适合的新问题。我们研究了这一点,以及更广泛的选拔和评估程序有效性问题。
数据包括背景特征、学术记录、面试分数以及两年制研究生入学医学生的临床前模块评估表现。探索性因素分析是一种将大量测量值简化为少数潜在因素的强大方法。在这里,它用于识别选择和表现数据内部和之间的模式。
基本背景特征对考试成功的预测作用不大。然而,在构成“选择”和“评估”标准的变量中,检测到了易于解释的成分。确定了三个选择因素(“学术”、“GAMSAT”、“面试”)和四个评估因素(“普通考试”、“肿瘤学”、“客观结构化临床考试”、“家庭病例研究”)。大多数选择和表现因素之间几乎没有关系。只有“普通考试”和“学术”表现出相关性(Pearson r=0.55,p<0.001)。
本研究提出了关于学生选拔方法及其在预测表现和评估医学职业适合性方面的有效性的问题。入学考试和大多数考试仅证实了以前的学术成就,而面试成绩与任何后续评估均无相关性。
