The Drug Use Screening Inventory for adults: psychometric structure and discriminative sensitivity.
The psychometric structure and characteristics of the adult version of the Drug Use Screening Inventory were examined in alcohol and drug abusers (n = 119) and normal controls (n = 119). It was found that each of the 10 DUSI domains is unidimensional. Inter-item, split half and internal reliability ranged from good to excellent. A score of 4 or higher on the Substance Use Domain correctly classified 80% of the substance abusers whereas a score of 3 or less accurately detected 100% of the normal control subjects. These results demonstrate that the DUSI is a practical and psychometrically sound screening instrument.
