문항반응이론을 적용한 1급 응급구조사 국가시험 대비 모의시험의 적정성 연구
A study of the adequate number of questions in a mock test for the paramedic national examination using item response theory
Purpose: To adjust item numbers in a national test, this study used item response theory to examine changes in average scores, reliability, difficulty, and discrimination according to the adjustment of item numbers. Methods: We analyzed the dichotomous coding of correct and incorrect answers of 473 examinees in a mock test conducted in 2023. Additionally, as an explanatory pilot study, we used an online questionnaire to survey experts on their perceptions of the appropriate item numbers for each test subject from January 18, 2024, to February 15, 2024. Results: Regarding the item numbers on the national exam, experts preferred to reduce the number of management of emergency patients (33.14±6.09, p<.05) and advanced emergency medical care: subtopics (104.49±11.55, p<.05), and the total number of questions (217.82±20.95, p<.05). In a simulation set in which items with low item fit were removed after fitting a two-parameter item response theory model, reliability was maintained at .910 until the 5th test consisting of 185 questions with little loss of difficulty, discrimination, and average score, and there was no correlation between item numbers and average score. Conclusion: Experts responded that reducing the number of items on the national exam was appropriate. As a result of the item reduction simulation, there was no significant loss in the average score, difficulty, discrimination, or reliability. More reliable results could be obtained if the results were based on a validity analysis and analyzed using actual national exams.

소개
복합 구조적인 산업사회의 발전에 따라 안전사고와 응급상황에서의 구조구급요청자들이 증가하고 있으나 우리나라의 응급의료체계는 아직 그 수준을 따라가지 못하고 있는 실정이다. 이에 우리나라의 응급의료체계를 확립하고 구조구급에 관한 기초학문의 발전에 기여하고자 학회를 창립한다.
