title: Psychometric characteristics of the Drug Use Disorders Identification Test (DUDIT) and the Drug Use Disorders Identification Test-Extended (DUDIT-E) among young drug users in Hungary.
abstract: BACKGROUND
  The Drug Use Disorders Identification Test (DUDIT) was developed for problematic substance use screening, and for a more detailed assessment of problematic use, the Drug Use Disorders Identification Test-Extended (DUDIT-E) was additionally developed.
  
  
  OBJECTIVE
  Examining the psychometric properties of DUDIT and DUIT-E across diverse settings in populations of young drug users.
  
  
  METHODS
  We examined the psychometric characteristics of these instruments across various settings in populations of young substance users differing in substance use severity and treatment status. Data were collected from three clinically relevant groups (n = 259) as well as a control sample of college students (n = 109).
  
  
  RESULTS
  Reliability analyses indicated good internal consistency for both instruments; high intraclass correlations further indicated good test-retest reliability. Differences among study groups were significant on the DUDIT scale and all DUDIT-E subscales (p < 0.01), with the target groups exhibiting higher scores compared to controls. A two-factor solution was identified for the factor structure of DUDIT.
  
  
  CONCLUSIONS
  The Hungarian version of DUDIT and DUDIT-E can effectively identify substance use problems among young users.
