有效和可靠的工具用于测量艾滋病毒感染者的实际、预期和内在化污名，对于绘制艾滋病毒相关污名流行趋势和跟踪减少污名干预措施的有效性至关重要。虽然存在较长的工具，例如Berger等人常用的40个项目的艾滋病毒污名量表，但较短的工具将有助于将艾滋病毒污名纳入更多和更广泛的调查。因此，这项工作的目的是开发一个大大缩短，但仍然有效的艾滋病毒污名量表版本。瑞典40个项目的艾滋病毒污名量表的心理测量评估数据被重新分析，以创建一个包含12个项目的简短版本(四个污名子量表各三个：个性化污名、披露担忧、对公众态度的担忧和负面自我形象)。随后，使用一项调查瑞典艾滋病毒携带者的耻辱和生活质量的全国性调查的数据，对简短版本的艾滋病毒污名量表进行了心理测量学测试(n=1880，平均年龄47.9岁，26%女性)。在没有交叉加载的探索性因素分析和验证性因素分析中，建议的简短版本的假设因素结构被复制，验证性因素分析支持结构效度，具有预期量表上项目的高度标准化效应(>；0.7)。χ2检验具有统计学意义(χ2=154.2，df=0.48，p<0.001)，但替代拟合度显示可接受的拟合度(相对拟合度指数：0.963，塔克-刘易斯指数：0.950，近似均方误差：0.071)。所有项目的校正项目-总相关系数为-gt；0.4，差异表明已捕捉到污名概念的广泛性。除两个方面外，该文书打算涵盖的与艾滋病毒有关的耻辱的所有方面都被简短版本中的选定项目所涵盖。没有丢失任何项目的方面被判断为具有可接受的心理测量学特性。短版仪器显示的地板和天花板效应比全长天平更高，这表明短版仪器的灵敏度有所下降。克朗巴赫各分量表的α均为0.70。虽然在测量上不那么敏感，但拟议的12个项目的艾滋病毒污名量表具有与全量表类似的心理测量学特性，并可在需要更短的工具时使用。
Valid and reliable instruments for the measurement of enacted, anticipated and internalised stigma in people living with HIV are crucial for mapping trends in the prevalence of HIV-related stigma and tracking the effectiveness of stigma-reducing interventions. Although longer instruments exist, e.g., the commonly used 40-item HIV Stigma Scale by Berger et al., a shorter instrument would be preferable to facilitate the inclusion of HIV stigma in more and broader surveys. Therefore, the aim of this work was to develop a substantially shorter, but still valid, version of the HIV Stigma Scale. Data from a psychometric evaluation of the Swedish 40-item HIV Stigma Scale were reanalysed to create a short version with 12 items (three from each of the four stigma subscales: personalised stigma, disclosure concerns, concerns with public attitudes and negative self-image). The short version of the HIV stigma scale was then psychometrically tested using data from a national survey investigating stigma and quality of life among people living with HIV in Sweden (n = 880, mean age 47.9 years, 26% female). The hypothesized factor structure of the proposed short version was replicated in exploratory factor analysis without cross loadings and confirmatory factor analysis supported construct validity with high standardised effects (>0.7) of items on the intended scales. The χ2 test was statistically significant (χ2 = 154.2, df = 48, p < 0.001), but alternate fit measures indicated acceptable fit (comparative fit index: 0.963, Tucker-Lewis index: 0.950 and root mean square error of approximation: 0.071). Corrected item-total correlation coefficients were >0.4 for all items, with a variation indicating that the broadness of the concept of stigma had been captured. All but two aspects of HIV-related stigma that the instrument is intended to cover were captured by the selected items in the short version. The aspects that did not lose any items were judged to have acceptable psychometric properties. The short version of the instrument showed higher floor and ceiling effects than the full-length scale, indicating a loss of sensitivity in the short version. Cronbach’s α for the subscales were all >0.7. Although being less sensitive in measurement, the proposed 12-item short version of the HIV Stigma Scale has comparable psychometric properties to the full-length scale and may be used when a shorter instrument is needed.
