PURPOSE This study aimed to develop a test scale to measure the character qualities of medical students as a follow-up study on the 8 core character qualities revealed in a previous report. METHODS In total, 160 preliminary items were developed to measure 8 core character qualities. Twenty questions were assigned to each quality, and a questionnaire survey was conducted among 856 students in 5 medical schools in Korea. Using the partial credit model, polytomous item response theory analysis was carried out to analyze the goodness-of-fit, followed by exploratory factor analysis. Finally, confirmatory factor and reliability analyses were conducted with the final selected items. RESULTS The preliminary items for the 8 core character qualities were administered to the participants. Data from 767 students were included in the final analysis. Of the 160 preliminary items, 25 were removed by classical test theory analysis and 17 more by polytomous item response theory assessment. A total of 118 items and sub-factors were selected for exploratory factor analysis. Finally, 79 items were selected, and the validity and reliability were confirmed through confirmatory factor analysis and intra-item relevance analysis. CONCLUSION The character qualities test scale developed through this study can be used to measure the character qualities corresponding to the educational goals and visions of individual medical schools in Korea. Furthermore, this measurement tool can serve as primary data for developing character qualities tools tailored to each medical school’s vision and educational goals.

使用多项项目反应理论和因子分析开发韩国医学生性格品质测试：初步量表开发研究

目的本研究旨在开发一个测试量表来衡量医学生的品格品质，作为对之前报告中揭示的 8 种核心品格品质的后续研究。方法 总共制定了 160 个初步项目来衡量 8 项核心品格品质。每个素质分配 20 个问题，对韩国 5 所医学院的 856 名学生进行了问卷调查。利用部分信用模型，进行多层次项目响应理论分析来分析拟合优度，然后进行探索性因子分析。最后对最终选定的项目进行验证性因素和信度分析。结果 对参与者进行了 8 项核心品格品质的初步测试。最终分析纳入了 767 名学生的数据。在160个初步项目中，25个通过经典测试理论分析被删除，另外17个通过多元项目反应理论评估被删除。共选取118个条目和子因素进行探索性因素分析。最终筛选出79个条目，通过验证性因子分析和条目内相关性分析确认有效性和信度。结论 通过本研究开发的品格品质测试量表可用于衡量与韩国各医学院的教育目标和愿景相对应的品格品质。此外，该测量工具可以作为开发适合每个医学院愿景和教育目标的性格品质工具的主要数据。
