Abstract
ABSTRACTObjective: Motivation is a widely used concept in substance use treatment, which is related to the change during treatment. The Drug Use Disorders Identification Test–Extended (DUDIT-E) is one of the instruments to measure motivation. Among clients who have been screened already for drug-related problems, DUDIT-E maps the frequency of illicit drug use (D), the positive (P) and negative (N) aspects of drug use, and treatment readiness (T). The aim of the present study was to evaluate the psychometric properties of the Turkish DUDIT-E in adult male patients with substance use disorder (SUD) in Turkey.Methods: We examined the psychometric characteristics of this instrument in a population of outpatients with SUD and who are under probation (n = 196). The participants were administered the Drug Use Disorders Identification Test (DUDIT), the DUDIT-E, and the Addiction Profile Index (API).Results: Cronbach’s alpha coefficient was 0.96 for P score, 0.95 for N score, and 0.85 for T score.

Substance use disorders (SUDs) are a worldwide public health problem [1]
For Drug Use Disorders Identification Test–Extended (DUDIT-E), the exploratory factor analysis (EFA) of the questionnaire’s 44 items (P, N, and T sub-dimensions) resulted in a 7-factor solution, which accounted for 68.6% of the total variance
Previous studies established the psychometric properties of the Turkish version of this scale in adult and adolescent substance users [5] and in prisoners with or without any drug use disorders [6]
Summary
Substance use disorders (SUDs) are a worldwide public health problem [1]. One of the several drug abuse screening instruments that have been developed to assess the severity of substance abusers’ drug use is the 11-item Drug Use Disorders Identification Test (DUDIT) [3]. Developed as an analogous instrument to the Alcohol Use Disorders Identification Test (AUDIT) [4], the questions on the DUDIT are parallel to those on the AUDIT with very few exceptions (i.e. two items on the AUDIT were deleted and three new items were added). The DUDIT was found to be a reliable and valid drug abuse screening instrument that measures a unidimensional construct in Turkish adolescent and adult patients with drug use disorder [5] and in a high-risk population of prisoners [6]
