摘要
目的编制高校新生公共卫生安全素养快速测评量表。方法采用文献研究和专家访谈法构建指标池,采用专家意见集中法遴选题项,编制初始量表,随机抽取一所高校的250名本科、硕士、博士新生进行实测。采用经典项目测验理论和项目反应理论进行题项缩减,并对另外抽取的318名新生的测试数据进行验证性因子分析。结果量表包含3个维度9个题项,遴选内容效度均≥0.8,题项难度系数为1.18~2.43,难度指数为0.41~0.78,鉴别力指数为0.38~0.64,27%高/低分组在各题项的得分差异均t>3,均P<0.05。各题项的Cronbach'sα值为0.72~0.77,矫正题项-总相关系数为0.33~0.60,整体α值为0.77。因子分析各条目的荷载>0.680,因子累积方差贡献率为62.484%。验证性因子分析结果显示模型整体适配度指标除χ^(2)值外均达适配标准。不同人口学特征学生量表总得分和在各题项上的得分差异无统计学意义(P>0.05)。结论高校新生公共卫生安全素养快速测评量表信度、效度、稳定性和题项恒定性均较好,可用于高校新生公共卫生安全素养的测评。
Objective To develop a measurement scale for the public health and safety literacy of university freshmen.Methods Item pooling was conducted through literature review and in-depth interview with public health experts,and a nominal group was organized to develop the initial items to form the questionnaire.A total of 250 freshmen were randomly selected to complete the questionnaire,and the assessment of psychometric properties were performed to carry out item reduction by using classical test theory and item response theory.Exploratory factor analysis method(EFA)was employed to calculate the item-factor loadings.The data collected from another 318 freshmen were analyzed using confirmatory factor analysis method(CFA).Results The scale contained 3 dimensions and 9 items with all content validity index≥0.8.The difficulty coefficient of 9 items was 1.18-2.43.The discriminative validity analysis showed that the difficulty index was 0.41-0.78,and the discrimination index was 0.38-0.64.Each of the remaining items had a statistically significant difference in the score value between the top 27%and lowest 27%of respondents(t>3,P<0.05).The item's Cronbach'sαwas 0.72-0.77,corrected item-total correlation was 0.33-0.60 and the overallαof the scale was 0.77.EFA indicated all item-factor loading were higher than 0.680,and the accumulated variance contribution of the 3 factors was 62.484%.Results of CFA showed that the overall fitness index of the model reached the fitness standard except for theχ^(2) value.There was no statistical significance in the total score of the scale and the scores of each item among groups with different demographic characteristics(P>0.05).Conclusions The newly developed public health safety literacy scale had a good reliability,validity,stability and item constancy.It can be used in measurement of the public health and safety literacy of university freshmen.
