Although recent research with the Disgust Scale-Revised (DS-R) has contributed to current knowledge regarding the structure of disgust, this line of research has exclusively employed adult samples. The current study extended existing research by examining the factor structure of the DS-R in an adolescent sample (N = 637). Exploratory factor analysis revealed three factors: Contagion, Mortality, and Contact Disgust. Subsequent to removing three items due to inadequate factor loadings, confirmatory factor analysis provided support for the 3-factor model across gender, grade level, and racial subgroups. Tests of item-intercept invariance also revealed no differences in item means across grade level. However, three and four items were associated with differences across race and gender, respectively. Latent factor means were also found to be invariant across racial groups and grade level, but not across gender. Implications of the DS-R factor structure in this adolescent sample and its domains are discussed.
虽然最近使用修订后的厌恶量表（DS-R）的研究对厌恶的结构有了更多的了解，但这条研究线仅使用了成人样本。本研究通过在青少年样本（N=637）中检查 DS-R 的因子结构，扩展了现有研究。探索性因素分析显示出三个因素：传染、死亡和接触厌恶。在由于因子负荷不足而删除了三个项目之后，验证性因素分析为跨性别、年级和种族亚组的 3 因子模型提供了支持。项目截距不变性检验也表明，年级水平之间的项目平均值没有差异。然而，三个和四个项目分别与种族和性别差异有关。潜因子均值也被发现跨种族群体和年级水平不变，但性别不同。讨论了该青少年样本中 DS-R 因子结构及其领域的意义。
