摘要： 目的·引入艾滋病病毒相关知识问卷（Brief HIV Knowledge Questionnaire，HIV-KQ-18），评价该问卷在艾滋病病毒阴性的性传播疾病（sexually transmitted diseases，STD）人群中测量的信度和效度，并根据其知识得分预测该人群的性行为。方法·将HIV-KQ-18汉化后，对2018年1月至2018年12月于上海市皮肤病医院门诊就诊的符合条件的599名STD患者进行评测，将其随机分成2部分，一部分（
n=300）进行探索性因子分析，另一部分（
n=299）进行验证性因子分析；将发生性行为时始终使用安全套判定为安全性行为并作为因变量，HIV-KQ-18得分作为自变量，作受试者工作特征曲线，评估问卷对安全性行为的预测能力及临界值。结果·探索性因子分析显示，该问卷可提取3个因子即艾滋病的传播（7个条目）、有效的预防措施（4个条目）和感染艾滋病的后果（3个条目）；从HIV-KQ-18剔除4个条目，形成中文版HIV-KQ-14。验证性因子分析显示，三因子修正模型拟合情况优良（
χ2/
df=2.046，近似误差的平方根=0.059，增值适配指数=0.926，Tucker-Lewis指数=0.908，比较拟合指数=0.925）。问卷的Cronbach′s
α系数为0.861，Spearman-Brown系数为0.815。问卷得分预测安全性行为曲线下面积为0.708（
P=0.000）。结论·中文版HIV-KQ-14在HIV阴性STD患者中有良好的信效度，对安全性行为有较好的预测能力。

Methods·A total of 599 eligible patients who attended the outpatient clinic of Shanghai Skin Disease Hospital from January 2018 to December 2018 were evaluated by the Chinese version of HIV-KQ-18, and they were randomly allocated into two groups for exploratory factor analysis (n=300) and confirmatory factor analysis (n=299). Consistent condom use when having sex was judged as safe sexual behavior and used as a dependent variable, and HIV-KQ-18 scores were used as independent variables for receiver operating characteristic curve analysis to predict safe sexual behavior.
Results·The exploratory factor analysis showed that three factors including the transmission of HIV (7 items), preventive measures (4 items) and consequences of being infected with HIV (3 items) could be extracted. Four items were removed from HIV-KQ-18 to form the Chinese version of HIV-KQ-14. Confirmatory factor analysis showed that the model revised by three factors fitted well (χ2/df=2.046, root mean square error of approximation=0.059, incremental fit index=0.926, Tucker-Lewis index=0.908, comparative fit index=0.925). The Cronbach′s α of the scale was 0.861, and the Spearman-Brown coefficient was 0.815; the area under the curve of safe sexual behavior was 0.708 (P=0.000).
Conclusion·The Chinese version of the HIV-KQ-14 has good reliability and validity in HIV-negative STD patients, and has a good predictive ability for safe sexual behavior.
