[EBP尺度の比較] How to choose an evidence-based medicine knowledge test for medical students? ...

There are a few studies of alignment between different knowledge-indices for evidence-based medicine (EBM). The aim of this study was to investigate whether the type of test used to assess knowledge of EBM affects the estimation of this knowledge in medical students. Medical students enrolled in 1-week EBM course were tested with the Fresno, Berlin, and ACE tests at the beginning and the end of the course. We evaluated the ability of these tests to detect a change in the acquired level of EBM knowledge and compared the estimates of change with those of the Control group that was tested with the ACE and Berlin tests before and after an unrelated non-EBM course. The distributions of test scores and average item difficulty indices were compared among the tests and the groups. Test scores improved on all three tests when compared with their pre-test results and the control. Students had on average a “good” performance on the ACE test, “sufficient” performance on the Berlin test, and “insuf
