The suitability of fitting a two-parameter logistic item response model to the Drug Use Screening Inventory (DUSI) was assessed. In a sample of 846 adolescents, each of the 10 domains was found to be unidimensional. Invariance of the item parameters across different groups was also observed. The reliability coefficient, based on item response theory, was found to be superior. The results of these analyses indicate that the DUSI has sound psychometric properties.
评估了两参数逻辑斯蒂项目反应模型对药物使用筛查量表（DUSI）的适配性。在一个846名青少年的样本中，发现10个领域中的每一个都是单维的。还观察到项目参数在不同组间的不变性。基于项目反应理论的信度系数被发现更优。这些分析结果表明DUSI具有良好的心理测量学特性。
