Usefulness of DETECT program to assess internal structure of dimensionality in simulated data and results of Korean Nursing Licensing Examination

The dimensionality of examinations provides empirical evidence to investigate the internal test structure underlying the responses to a set of items. The internal structure is one of the important evidence to demonstrate examination validity sources. Thus, aim of the study is to examine the internal structure of Korean nursing examinations and investigate performances of DETECT program. A real data study was conducted using data collected from Koran nursing licensing examinations taken by January 2014. It contains eight different subjects including the different item numbers. Each subject possesses its unique items that candidates require to learn as content objectives. Table 1 shows domain specification including the number of items. The number of examinees of real data was 16,085 and its number of items was 330.

考试的维度特征可为探究一组试题作答背后潜藏的内部测验结构提供实证依据。内部测验结构是验证考试效度来源的重要证据之一。因此，本研究旨在探究韩国护理类考试的内部测验结构，并检验DETECT程序的应用性能。本研究采用2014年1月前参加韩国护理执业资格考试的考生作答数据开展实证分析。该数据集涵盖8个不同考试科目，各科目试题数量各不相同。每个科目均设有专属试题，作为考生需掌握的内容目标范畴。表1展示了各测验领域的命题规范，其中包含试题数量信息。本次实证分析的有效考生人数为16085名，总试题数为330道。
