Outline of Final Research Achievements

The reliability of the objective structured clinical examination after clinical clerkship for 6th grade medical students, was studied based on the generalizability theory. The G coefficients was used as an index, and the target value was set to 0.9. The number of stations, raters per station, and the assessment items were set to 4-2-6 and 6-2-6, respectively, in FY2018 and FY2019, and the G coefficient were 0.705 and 0.782, respectively. In 2020, due to the COVID-19 epidemic, three stations were prepared. One of the raters was in the examination room, the other was from a remote location, and the G coefficient was 0.641.
In the simulation using this theory, the number of tasks required to achieve the goal was 22 with the FY2019 data.

Academic Significance and Societal Importance of the Research Achievements

医学部６年生向けの診療能力試験である診療参加型臨床実習後客観的臨床能力試験（Post-CC OSCE）に卒業試験として十分な信頼性を確保するためには、試験の量的な拡大に加え、質的な改善も必須であることが明らかとなった。
各大学を試験会場とした個別の実施は６課題で既に限界と考えられることから、より多くの課題が必要となれば試験会場の共有すなわちOSCEセンターの設置が望まれること、さらに、より均質な課題の開発、均質な評価者の育成が求められることを示唆する社会的意義の大きい研究成果である。
