Discrimination is associated with numerous psychological health outcomes over the life course. The nine-item Everyday Discrimination Scale (EDS) is one of the most widely used measures of discrimination; however, this nine-item measure may not be feasible in large-scale population health surveys where a shortened discrimination measure would be advantageous. The current study examined the construct validity of a combined two-item discrimination measure adapted from the EDS by Add Health (N = 14,839) as compared to the full nine-item EDS and a two-item EDS scale (parallel to the adapted combined measure) used in the National Survey of American Life (NSAL; N = 1,111) and National Latino and Asian American Study (NLAAS) studies (N = 1,055). Results identified convergence among the EDS scales, with high item-total correlations, convergent validity, and criterion validity for psychological outcomes, thus providing evidence for the construct validity of the two-item combined scale. Taken together, the findings provide support for using this reduced scale in studies where the full EDS scale is not available.

歧视与生命历程中的许多心理健康结果有关。九项日常歧视量表 (EDS) 是最广泛使用的歧视衡量标准之一；然而，这项九项措施在大规模人口健康调查中可能不可行，因为缩短歧视措施将是有利的。当前的研究检验了根据 Add Health 的 EDS 改编的组合两项目歧视衡量标准（ N = 14,839）与完整的九项目 EDS 和两项目 EDS 量表（与改编后的组合衡量标准平行）的结构效度。 ）用于全国美国人生活调查（NSAL； N = 1,111）和全国拉丁裔和亚裔美国人研究（NLAAS）研究（ N = 1,055）。结果表明，EDS 量表之间具有收敛性，具有较高的项目总相关性、收敛效度和心理结果标准效度，从而为两项目组合量表的结构效度提供了证据。总而言之，这些发现为在无法获得完整 EDS 量表的研究中使用这种缩小的量表提供了支持。
