艾滋病母婴传播态度量表的效度和信度评价

目的评价艾滋病母婴传播态度量表。方法参考国内外文献设计出含16个条目的艾滋病母婴传播态度量表,用因子分析评价结构效度;区分效度通过对大学本科及以上和本科以下其他学历孕产妇的态度总分差异分析来进行评价;用Cronbach浕系数和折半信度来评价量表的内部信度;比较前后两次的得分差异和相关系数来评价重测信度。结果因子分析提取3个主成分解释总变异的52.21%,旋转后因子1定义为对艾滋病人及防控艾滋病母婴传播责任误解因子,因子2定义为不影响生育情况下对艾滋病母婴传播防控的认同因子,因子3定义为可能影响生育情况下对艾滋病母婴传播防控的认同因子;大学本科及以上的人得分高于本科以下学历的人。3个因子和全部条目的Cronbach浕系数分别为0.812,0.794,0.653和0.786,折半信度分别为0.759,0.799,0.569和0.728,重测（65人）相关系数分别为0.665,0.766,0.492,0.721,关联有显著性;两次调查的差异无显著性。结论量表具有较好的效度和信度,可以为国内类似调查提供参考。

Assessment on a scale for measuring mother to infant transmission of AIDS-related attitude

Objective To estimate the scale used to measure mother to infant transmission of AIDS-related attitude.Methods Based on literatures published in China and abroad,a scale with 16 items was designed to measure mother to infant transmission of AIDS-related attitude.Factor analysis was used to assess the construct validity of the scale.The differences of the scores between those with undergraduation/postgraduation level and those below that level were tested for assessing the discriminant validity of the scale....
