医学生公共卫生伦理认知水平调查问卷的编制

Preparation of a Questionnaire on Medical Students'Cognition Level of Public Health Ethics

目的编制医学生公共卫生伦理认知水平调查问卷,为了解医学生对公共卫生伦理的认知水平提供科学、客观的评价工具。方法在文献回顾和专题小组讨论的基础上编制初始问卷,采用德尔菲法对12名专家进行3轮函询,拟定最终问卷,并采用探索性因子分析及内在一致性对问卷进行评价。结果三轮函询中专家积极性均为100%;权威系数为0.84;变异系数分别为0~0.32、0~0.26、0~0.12;协调系数分别为0.206、0.163、0.250(P值均<0.05);项目分析显示问卷条目临界比率值及相关系数差异均具有统计学差异;结构效度分析显示提取的2个公因子累积方差贡献率为61.015%;内在一致性信度分析显示问卷Cronbach’sα系数为0.956;最终形成了26个条目的问卷,包括公共卫生伦理学的知识、公共卫生伦理学的应用2个维度。结论医学生公共卫生伦理认知水平调查问卷具有可靠性,且信效度较好,可作为医学生公共卫生伦理认知水平的调查工具。

Objective:To construct a questionnaire on medical students'cognition level of public health ethics,and to provide a scientific and objective evaluation tool for understanding the cognitive level of medical students on public health ethics.Methods:Based on the literature review and focus group discussion,the initial questionnaire was constructed.The Delphi method was used to conduct three rounds of correspondence with 12 experts,and the final questionnaire was drafted.And exploratory factor analysis and internal consistency were used to evaluate the questionnaire.Results:In the three rounds of correspondence,the enthusiasms of experts were all 100%,the authority coefficients were all 0.84,the coefficients of variation were 0~0.32,0~0.26,0~0.12,respectively,and the coordination coefficients were 0.206,0.163,and 0.250,respectively(all P<0.05).The analysis of the items showed that the critical ratio values and related coefficients of the questionnaire items were statistically different.The structural validity analysis showed that the cumulative variance contribution rate of the extracted two common factors was 61.015%.The intrinsic consistency reliability analysis showed that the questionnaire Cronbach's coefficient was 0.956.Finally,the questionnaire of 26 items was formed,including two dimensions:knowledge of public health ethics and application of public health ethics.Conclusion:The questionnaire on medical students'cognition level of public health ethics is reliable and has good reliability and validity,and can be used as a tool for medical students'public health ethics cognition level.
