The Explicit Discrimination Scale (EDS) was developed to assess experiences with discrimination in Brazilian epidemiologic surveys. Though previous analyses have demonstrated that the EDS has good configural, metric, and scalar properties, its invariance has not yet been investigated. In this study, we examined the factorial invariance of two abridged versions of the EDS, according to skin color/ethnicity, sex, socioeconomic status, and their intersections.
Data from the EpiFloripa Adult Study were used, which include a representative sample of adults residing in a state capital of southern Brazil (n=1,187). Over half of the respondents were women, and around 90% identified as white; the mean age of the participants was 39 years. Two abridged versions of the EDS were analyzed, with seven and eight items, using Multigroup Confirmatory Analysis and the Alignment method.
The two versions of the scale may be used to provide estimates of discrimination that are comparable across skin color/ethnicity, sex, socioeconomic status, and their intersections. In the seven-item version of the scale, only one parameter lacked invariance (i.e., threshold of item i13 - called by names you do not like), specifically among black respondents with less than 12 years of formal education.
The EDS may provide researchers with valid, reliable, and comparable estimates of discrimination between different segments of the population, including those at the intersections of skin color/ethnicity, sex, and socioeconomic status. However, future research is needed to determine whether the patterns we identified here are consistent in other population domains.
明确歧视量表（EDS）是为评估巴西流行病学调查中的歧视经历而编制的。尽管先前的分析表明EDS具有良好的构型、度量和标度属性，但其不变性尚未得到研究。在本研究中，我们根据肤色/种族、性别、社会经济地位及其交叉情况，检验了EDS两个简化版本的因子不变性。
使用了来自弗洛里亚诺波利斯成人研究的数据，其中包括居住在巴西南部一个州首府的成年人的代表性样本（n = 1187）。超过一半的受访者为女性，约90%的人自认为是白人；参与者的平均年龄为39岁。使用多组验证性分析和对齐方法，对EDS的两个简化版本（分别有7个和8个项目）进行了分析。
该量表的两个版本可用于提供在肤色/种族、性别、社会经济地位及其交叉情况方面具有可比性的歧视估计。在量表的7个项目版本中，只有一个参数缺乏不变性（即项目i13的阈值——被称呼你不喜欢的名字），具体是在正规教育年限少于12年的黑人受访者中。
EDS可为研究人员提供关于不同人群细分之间歧视的有效、可靠且可比的估计，包括那些处于肤色/种族、性别和社会经济地位交叉点的人群。然而，需要未来的研究来确定我们在此处识别的模式在其他人群领域是否一致。
