Using data from two studies conducted among diverse undergraduate students, we assessed the scalar structure of the Explicit Discrimination Scale (EDS), and developed an abridged version of the instrument. Our findings suggest that the EDS has acceptable scalability properties, including an adequate dispersion of items along the latent trait continuum. Results also support the idea that increasing raw scale scores reflect higher intensities of perceived discrimination. This shortened version of the EDS may be used in large-scale studies on the health impacts of discrimination.

扩大对歧视和健康的研究：精简的显性歧视量表

使用在不同本科生中进行的两项研究的数据，我们评估了显性歧视量表 (EDS) 的标量结构，并开发了该工具的精简版。我们的研究结果表明，EDS 具有可接受的可扩展性特性，包括项目沿潜在特征连续体的充分分散。结果还支持这样一种观点，即增加原始量表分数反映了更高强度的感知歧视。EDS 的这种缩短版本可用于关于歧视对健康影响的大规模研究。
