The distribution and the statistical accuracy of scores on the Drug Use Screening Inventory (DUSI) and the discriminative power of the DUSI for identifying individuals who qualify for a DSM-III-R diagnosis of Psychoactive Substance Use Disorder (PSUD) were examined in 846 adolescents. The subjects with PSUD had higher mean scores, and the distribution of their scores approximated a normal distribution in each of the 10 domains measured by the DUSI. All of the DUSI domains yielded more precise trait estimates for the subjects who had more severe PSUD. Within the normal sample, using a score of 30 on the overall problem density index as the cutoff score, the DUSI correctly classified 95% of the normal sample and 81% of the PSUD cases.
对846名青少年进行了研究，考察了药物使用筛查量表（DUSI）得分的分布及统计准确性，以及DUSI对识别符合精神活性物质使用障碍（PSUD）DSM-III-R诊断标准个体的判别能力。患有PSUD的受试者平均得分更高，在DUSI测量的10个领域中，他们的得分分布均近似正态分布。对于患有更严重PSUD的受试者，所有DUSI领域都能得出更精确的特质估计值。在正常样本中，以总体问题密度指数30分为临界值，DUSI正确分类了95%的正常样本和81%的PSUD病例。
