NORMS AND SENSITIVITY OF THE ADOLESCENT VERSION OF THE DRUG-USE SCREENING INVENTORY

The distribution and the statistical accuracy of scores on the Drug Us e Screening Inventory (DUSI) and the discriminative power of the DUSI for identifying individuals who qualify for a DSM-III-R diagnosis of P sychoactive Substance Use Disorder (PSUD) were examined in 846 adolesc ents. The subjects with PSUD had higher mean scores, and the distribut ion 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. Wit hin the normal sample, using a score of 30 on the overall problem dens ity index as the cutoff score, the DUSI correctly classified 95% of th e normal sample and 81% of the PSUD cases.
