Background and Objectives: The current study was conducted to assess factor structure, validity, and reliability of the Persian version of the Drug Use Disorders Identification Test (DUDIT) among drug abusers in many city of Iran. It also assessed the DUDIT scores of a number of demographic factors.
Methods: The LDQ underwent forward translation to to Persian abackward translation to English. Furthermore, it was compared with the original scale. We made essential changes after it was used by 20 participants. Two hundred and eighty one drug abusers from prisons, dormitories, and rehabilitation camps completed the questionnaire. A demographic questionnaire as well as the Drug Use Disorders Identification Test (DUDIT), Severity of Dependence Scale (SDS), and Leeds Dependence Questionnaire (LDQ) were used to collect data. Methods used for data analysis included Confirmatory factor analysis, Cronbach’s alpha coefficient, Guttman split-half coefficient and convergent reliability.
Results: Findings supported the unidimensional structure of the DUDIT. The Cronbach’s alpha and Guttman scale score were 0.81 and 0.68, respectively. The convergent validity through calculation of the correlation coefficient of the DUDIT with LDQ and SDS was 0.61 and 0.46, respectively. History of drug abuse in the family, residence in rehabilitation camps, taking several substances simultaneously, and use several methods of drug abuse simultaneously obtained the highest score in the DUDIT.
Conclusion: The Persian version of the DUDIT has suitable psychometric properties in drug abusers. It is important to pay attention to the demographic factors affecting drug use disorders for prevention and treatment plans.
