中文摘要:
      目的 通过编制预防医学本科毕业生基本能力自评量表及进行量表的信度效度检验,为评价毕业生基本能力提供可靠的测量工具。方法 在构建《预防医学本科毕业生基本能力评价指标体系》的基础上,将三级指标转化为具体问题,经过预调查及专家论证,最终形成58个条目、22个子维度、8个主维度的自评量表。选取某校2017届、2018届205名预防医学本科毕业生及9位公共卫生教育专家进行问卷调查,应用内部一致性信度及组合信度对量表信度进行检验,应用内容效度和验证性因子分析对量表效度进行检验。结果 量表的内部一致性信度α系数为0.976;8个主维度的α系数及组合信度均大于0.8;量表的内容效度指数S-CVI为0.94,条目水平的内容效度指数I-CVI为0.78~1.00;8个主维度的平均方差抽取量(AVE)均大于0.50,以条目为观察指标的结构模型拟合合理(?字2/df=1.749,RMR=0.036,RMSEA=0.061,NFI=0.801,IFI=0.904,TLI=0.904,CFI=0.903),而以子维度为观察指标的结构模型拟合良好(?字2/df=1.876,RMR=0.032,RMSEA=0.066,NFI=0.913,IFI=0.958,TLI=0.945,CFI=0.957)。结论 此次编制的量表是依据《公共卫生与预防医学类教学质量国家标准》制定的预防医学本科毕业生的基本能力自我测评量表,具有良好的信度和效度,可实现毕业生基本能力的量化评价。
英文摘要:
      Objective To design the self-rating scale on basic ability in graduates of preventive medicine major, and test its reliability and validity, providing a reliable tool for evaluating the basic ability of graduates. Methods On the basis of constructing the Evaluation Index System on Basic Ability in Graduates of Preventive Medicine Major, the three-level indexes were converted to specific questions. Self-evaluation scale including 58 items, 22 sub-dimensions and 8 main dimensions were finally designed after pre-survey and expert argumentation. A total of 205 graduates of preventive medicine major from a medical college and 9 experts in the field of public health were selected to completed the questionnaire. Scale's reliability was tested by applying internal consistency reliability and composite reliability; it's validity was tested by applying content validity and confirmatory factor analysis. Results Scale's α coefficient of internal consistency reliability was 0.976; α coefficient and combination reliability of eight main dimensions were both higher than 0.8; the content validity index S-CVI of the scale was 0.94, the content validity index I-CVI of the item level was 0.78 to 1.00; the average variance extraction amount (AVE) of the eight main dimensions was higher than 0.50. Fitting of the structural model with the item used as observation indexes was reasonable ( ?字2/df=1.749, RMR=0.036, RMSEA=0.061, NFI=0.801, IFI=0.904, TLI=0.904, CFI=0.903), and the sub-dimension as used observation indexes was good(?字2/df=1.876, RMR=0.032, RMSEA=0.066, NFI=0.913, IFI=0.958, TLI=0.945, CFI=0.957). Conclusion This scale is the first self-rating scale on the basic ability in graduates of preventive medicine major on the basis of the National Standards of Teaching Quality on Public Health and Preventive Medicine, with good reliability and validityl. It is able to achieve quantitative evaluation on graduates' basic abilities.
