Background and Objective: Current study was conducted to assess factor structure, validity and reliability of the Persian version of Drug Use Disorders Identification Test (DUDIT) among drug abusers in Iran. It has also been assessed DUDIT scores about a number of demographic factors.

Method: LDQ was translated to Persian and subsequently it was translated reversely. Furthermore, it was compared with original scale. We made essential changes after using scale among 20 participants. 281 drug abusers from prison, dormitory and rehabilitation camps were completed the questionnaire. Questionnaires of demographic information, Drug Use Disorders Identification Test (DUDIT), Severity of Dependence Scale (SDS) and Leeds Dependence Questionnaire (LDQ) were used in order to obtain data. Methods used for data analysis includes Confirmatory factor analysis, Cronbach’s alpha coefficient, Guttman split-half coefficient and convergent reliability.

Results: Findings supported the unidimensional structure of DUDIT. Scores of Cronbach’s Alpha and Guttman scale were measured as 0.81 and 0.68 respectively. Assessment of convergent validity by computing correlation coefficient of DUDIT scale with LDQ and SDS was 0.61 and 0.46 respectively. Using history of family, residence in rehabilitation camp, taking several substances simultaneously and the using several methods simultaneously obtained highest score in DUDIT.

Conclusion: The Persian version of DUDIT has suitable psychometric properties among the Iranian population of drug abusers. Regarding to demographic factors affecting on enhancement of drug use disorders is necessary for prevention and treatment plans.
