Are analytic global OSCE ratings sensitive to level of training?
In this study, a summated analytic global rating demonstrated construct validity, as did 2 of the 4 scales measuring specific traits. In addition, the analytic global rating showed substantially higher internal consistency than did the checklists, a finding consistent with that seen in previous studies cited in the literature. Global ratings are an important element of OSCE measurement and can have good psychometric properties. However, OSCE researchers should clearly describe the type of global ratings they use. Further research is needed to define the most effective global rating scales.
In hyperacute cerebral infarction within 3 hours after onset, MDM, as compared with CDM, was able to detect DPM with higher sensitivity and specificity. This suggests that MDM is more reflective of DPM.
