The DUDIT Study

Ref: Berman, A. H., Bergman, H., Palmstierna, T., & Schlyter, F. (2005). Evaluation of the Drug Use Disorders Identification Test (DUDIT) in Criminal Justice and Detoxification Settings and in a Swedish Population Sample.
European Addiction Research, 11(1), 22-31.

Abstract: Psychometric properties of the 11-item self-report Drug Use Disorders Identification Test (DUDIT) were evaluated in a sample of heavy drug users from prison, probation, and inpatient detoxification settings, and in a general Swedish population sample. In the drug user sample, the DUDIT predicted drug dependence with a sensitivity of 90% for both DSM-4 and ICD-10 and a respective specificity of 78 and 88%. Reliability according to Cronbach’s alpha coefficient was 0.80. In the population sample, 3.1% scored positive on the DUDIT; T-score values are suggested.
The DUDIT screens effectively for drug-related problems in clinically selected groups and may prove useful in the context of public health surveys 


Drug Use Disorders Identification Test is in the public domain but the layout is copyrighted. This means that if one wants to use the DUDIT clinically or in research and use the data we present in the manual or in the article as a basis for evaluating responses, this is only valid if the DUDIT is used as is.
