The objective of this study was to design and assess measurement instruments that accurately measure the levels of stigma among individuals with a primarily collectivist culture. A cross-sectional study was conducted among middle school students and their parents or guardians in a rural area of China. Exploratory and confirmatory factor analyses were used to examine and determine the latent factors of the sub-scales of stigma respectively, among students and their parents. Factor analyses identified three sub-scales: HIV public stigma (seven items), drug-use public stigma (nine items), and fear of HIV infection (seven items). There were no items with cross-loading onto multiple factors, supporting the distinctness of the constructs that these scales were meant to measure. Goodness of fit indices indicated that a three-factor solution fit, the data at an acceptable level in the student sample (χ(2) /degree ratio=1.98, comparative fit index [CFI]=0.92, root mean square error of approximation [RMSEA]=0.055, standardized root mean square residual [SRMR]=0.057) and in the parent sample (χ(2)/degree ratio=1.95, CFI=0.91, RMSEA=0.06, SRMR=0.059). Reliability of the three scales was excellent (Cronbach's alpha: 0.78-0.92 for students; 0.80-0.94 for parents or guardians) and stable across split samples and for the data as a whole. The scales are brief and suitable for use in developing countries where the collectivist culture prevails.
本研究的目的是设计并评估能够准确测量以集体主义文化为主的个体耻辱感水平的测量工具。在中国农村地区的中学生及其父母或监护人中开展了一项横断面研究。分别运用探索性和验证性因素分析来检验并确定学生及其父母耻辱感分量表的潜在因素。因素分析确定了三个分量表:艾滋病公众耻辱感(7个条目)、吸毒公众耻辱感(9个条目)以及对艾滋病感染的恐惧(7个条目)。没有条目在多个因素上存在交叉负荷,这支持了这些量表旨在测量的构念的独特性。拟合优度指数表明,三因素模型在学生样本(卡方/自由度比值=1.98,比较拟合指数[CFI]=0.92,近似均方根误差[RMSEA]=0.055,标准化均方根残差[SRMR]=0.057)和家长样本(卡方/自由度比值=1.95,CFI=0.91,RMSEA=0.06,SRMR=0.059)中对数据的拟合程度处于可接受水平。这三个量表的信度极佳(克朗巴哈系数:学生为0.78 - 0.92;父母或监护人为0.80 - 0.94),在拆分样本以及整体数据中都很稳定。这些量表简短,适用于集体主义文化盛行的发展中国家。
