The self-report Drug Use Disorders Identification Test—Extended (DUDIT-E): Reliability, validity, and motivational index

Psychometric properties of the Turkish version of Drug Use Disorders Identification Test–Extended (Turkish DUDIT-E) in substance-dependent adults under probation

“…A quick assessment of the extent of drug problems is essential for planning appropriate treatment and prevention strategies [2]. 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].…”

“…Secondly, the DUDIT includes a drug list with commonly abused prescription medications for clients' and counselors' easy reference. Thirdly, the DUDIT is suitable for use in public health surveys of drug use [2]. 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].…”

“…Although there are several instruments available for measuring treatment motivation, a more time-efficient and targeted measure of treatment motivation, such as the Drug Use Disorders Identification Test-Extended (DUDIT-E), could be useful in settings where time is limited [2]. The questionnaire was created to provide detailed information about substance use, excluding alcohol, including patients' perceptions about use.…”

“…Also based on these dimensions, a Motivational Index (MotInd) is calculated as a ratio of positive to negative aspects of substance abuse, multiplied with readiness, in order to get a simple index of motivation. According to Berman et al [2], the three dimensions comprising MotInd are composed of distinct subcomponents contributing to the factors. The P and N factors are both made up of four components, and the T factor has three subcomponents.…”

“…The P and N factors are both made up of four components, and the T factor has three subcomponents. The original scale was studied in a sample of heavy drug users, which yielded a Cronbach's alpha coefficient of 0.88 for both P and N aspects of using drugs and 0.72 for the T section; in a separate sample of prison inmates, Cronbach's coefficients were 0.92, 0.90, and 0.81, respectively [2]. To date, Berman et al's original Swedish scale has been adapted to Bosnian, Danish, English, Finnish, French, German, Hungarian, Portuguese, Norwegian, Mandarin Chinese, Russian, and Turkish and was approved by European Monitoring Centre for Drugs and Drug Addiction [7].…”
