预防医学专业本科生流行病学课程学习效果及影响因素分析

Analysis of the Learning Effect and Influencing Factors of Epidemiology Course for Undergraduate Students Majoring in Preventive Medicine

摘要: 目的：了解预防医学专业本科生流行病学课程的学习现状及影响因素。方法：采用问卷调查获取资料，计算Cronbach’s α系数衡量问卷内部一致性信度，通过t检验、方差分析、Pearson相关性分析及多重线性回归分析识别影响学生掌握流行病学知识的相关因素。结果：本次调查共有92名学生参与，学生流行病学掌握情况总体平均分为3.21分；学生统计掌握情况(β = 0.406, P < 0.001)及对流行病学的难易程度评价(β = 0.395, P= 0.001)是影响流行病学课程掌握情况的主要因素。结论：预防医学专业本科生流行病学总体掌握情况一般，学生统计掌握情况及对课程难易程度是影响学生掌握流行病学的主要影响因素。

Abstract: Objective: To understand the learning status and influencing factors of Epidemiology course for undergraduate students majoring in preventive medicine. Methods: Questionnaire was applied to obtain data. Cronbach’s alpha coefficient was calculated to measure the internal consistency reliability of the questionnaire, and the relevant factors that affect students’ mastery of epidemiological knowledge were identified through t-test, analysis of variance, Pearson correlation analysis and multiple linear regression analysis. Results: A total of 92 students were included in this survey, with an overall average score of 3.21 for their understanding of epidemiology; the mastery of medical statistics by students (β = 0.406, P < 0.001) and the difficulty level of epidemiology (β = 0.395, P = 0.001) are the main factors affecting the mastery of epidemiology. Conclusion: Undergraduate students majoring in preventive medicine have a general level of understanding of epidemiology, and their mastery of medical statistics and the difficulty of the course are the main factors affecting their understanding of epidemiology.
