摘　　要：目的基于实际调查分析整合问卷《大学生艾滋病相关KAP(知信行)调查问卷》的内部结构,并提出分析与优化策略。方法对江苏省某高校全日制在校生,通过“问卷星”网络平台发放问卷、收集数据。两次探索性因子分析用于分析和优化问卷结构,采用相关系数分析问卷条目间和因子关系,Cronbach′sα系数评价问卷信度。结果共调查1100份问卷,有效问卷1045份。1045名大学生中,男生为227人(21.7%),女生818人(78.3%),平均年龄(20.30±2.14)岁;初次探索性因子分析得22个因子,累积方差贡献率为64.0%;二次探索性因子分析提取了5个因子,累积方差贡献率达62.4%。全问卷的Cronbach′sα系数为0.780,艾滋病危险行为倾向、宣教服务与关注度、艾滋病知识、宣教需求与自我认知、艾滋病态度等维度的Cronbach′sα系数分别为0.862、0.861、0.598、0.596、0.578。宣教服务与关注度和艾滋病态度维度间相关性最强。结论《大学生艾滋病相关KAP(知信行)调查问卷》的结构效度和信度处于可接受水平,本研究基于实际调查对整合问卷的结构化分析和优化的分析策略可以用于类似的研究。Objective To analyze the structure of the questionnaire on Knowledge,Attitudes and Behaviors Related to AIDS among College Students,and propose strategies for its optimization.Methods Full-time students in a university in Jiangsu province were selected as subjects.Wenjuanxing,a network platform,was used to distribute the e-questionnaire and collect the data.2-time exploratory factor analyses were used to explore the design structure of the questionnaire for optimization.Correlation analysis was used to study the relationship between the items and factor scores.The Cronbach′sαcoefficient was used to evaluate the reliability of the questionnaire.Results The first exploratory factor analysis obtained 22 factors with a cumulative variance contribution rate of 63.95%.The second exploratory factor analysis extracted 5 factors with a cumulative variance contribution rate of 62.35%.The Cronbach′sα-coefficient of the whole questionnaire was 0.780,and the Cronbach′sαcoefficients of tendency towards AIDS risk behavior,promotional service&attention,AIDS knowledge,promotional needs&self-cognition,attitude towards AIDS were 0.862,0.861,0.598,0.596,and 0.578,respectively.The correlation between promotional services&attention and attitude towards AIDS was the strongest.Conclusion The structural validity and reliability of Questionnaire on Knowledge,Attitudes and Behaviors Related to AIDS among College Students are acceptable.The structural analysis and optimization of the questionnaire based on the survey data can be used for similar studies to improve the structure of the questionnaire.
