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。
Objective To evaluate the attitude of mother-to-child transmission of AIDS. Methods A 16-item HIV / AIDS attitude questionnaire was designed with reference to domestic and international literatures, and the structural validity was evaluated by factor analysis. The discriminant validity was evaluated by analyzing the difference of attitude scores among undergraduates and undergraduates with other qualifications of pregnant women The Cronbach’s coefficient and half-reliability were used to evaluate the internal reliability of the scale. The difference between the scores before and after the test was compared with the correlation coefficient to evaluate the test-retest reliability. Results The factor analysis extracted three main components to explain 52.21% of the total variance. The post-rotation factor 1 was defined as a misleading factor for the responsibility of HIV / AIDS prevention and control of mother-to-child transmission. Factor 2 was defined as not influencing the prevention of mother- Control of the identity factor, factor 3 is defined as likely to affect the situation of maternal and child transmission AIDS prevention and control of identity factors; undergraduate and above who score higher than undergraduate education. The Cronbach’s coefficients of three factors and all items were 0.812, 0.794, 0.653 and 0.786, respectively, and the half-reliability values were 0.759, 0.799, 0.569 and 0.728, respectively. The correlation coefficients of 65 participants were 0.665,0.766,0.492 and 0.721 , The correlation was significant; there was no significant difference between the two surveys. Conclusion The scale has good validity and reliability, which can provide reference for similar domestic surveys.
