Drug Use Disorders Identification Test (DUDIT)
Drug Use Disorders Identification Test · Also known as: DUDIT
The DUDIT is a brief, gender-sensitive screening instrument designed to identify individuals with harmful or hazardous drug use patterns across a wide range of substances. Developed by Berman and colleagues in 2005, it serves as a primary care and public health screening tool to detect drug-related problems before they escalate to dependence or disorder. The DUDIT is freely available and has been validated in multiple languages and settings.

When to use it
The DUDIT is appropriate for use in primary care, addiction medicine clinics, emergency departments, correctional facilities, occupational health services, and research settings where rapid screening for harmful drug use is needed. It is particularly useful for identifying individuals across a broad spectrum of substances (cannabis, amphetamines, opioids, cocaine, hallucinogens, inhalants, etc.) and for monitoring outcomes in treatment-seeking populations. The DUDIT is less suitable for diagnostic confirmation or severity staging; clinical interview and additional structured assessments are necessary for those purposes.
Strengths & limitations
- Brief and free-to-use screening instrument requiring minimal training or resources
- Gender-sensitive cutoff scores improve detection accuracy across male and female populations
- Covers multiple dimensions of drug use (frequency, consequences, withdrawal, social impact)
- Validated in diverse settings including criminal justice, treatment facilities, and community samples
- Demonstrated sensitivity and specificity for identifying harmful drug use across multiple substance classes
- Screening instrument, not diagnostic; cannot establish specific substance use disorder diagnoses
- May miss individuals with subtle or early-stage problematic use if consequences are not yet apparent
- Performance varies across substances; less sensitive for some drug classes than others
- Depends on self-report and may be subject to underreporting or minimization, particularly in criminal justice contexts
Frequently asked
Can the DUDIT be used to diagnose substance use disorder?
No. The DUDIT is a screening instrument designed to identify harmful or hazardous drug use, not to diagnose substance use disorders. A positive DUDIT screen indicates need for further clinical assessment, including comprehensive history, DSM-5 criteria evaluation, and assessment of consequences across life domains.
Why are the cutoff scores different for men and women?
Research shows that women experience greater harm and social consequences from drug use at lower consumption levels compared to men, due to physiological, psychological, and social factors. The gender-specific cutoffs (≥6 for men, ≥2 for women) optimize sensitivity and specificity in each population.
How long does it take to administer the DUDIT?
The DUDIT takes approximately 3–5 minutes to complete as a self-report measure, or 5–10 minutes if administered by a clinician in interview format.
Is the DUDIT free and available for use?
Yes, the DUDIT is in the public domain and is freely available for clinical, research, and training use. No permission or licensing fee is required.
Can the DUDIT be used to assess severity of substance use disorder?
The DUDIT is not designed for severity assessment. It identifies the presence or absence of harmful drug use above a defined threshold. For severity staging and treatment planning, use dedicated instruments such as the ASAM Criteria or supplementary addiction severity measures.
What substances does the DUDIT cover?
The DUDIT assesses use across a broad range of illicit and non-medical drugs, including cannabis, amphetamines, cocaine, opioids, benzodiazepines, hallucinogens, and inhalants. It does not include alcohol or tobacco; use AUDIT or Fagerstrom scales for those substances.
