Diagnosis and Classification of Alcohol Use Disorder

Diagnostic Criteria (DSM‑5, American Psychiatric Association)

Alcohol Use Disorder is diagnosed when an individual meets at least two of the eleven DSM‑5 criteria within a 12‑month period, indicating a pattern of alcohol use that causes clinically significant impairment or distress. 1, 2, 3
The eleven criteria are: loss of control over amount or duration of drinking; unsuccessful attempts to cut down; excessive time spent obtaining, using, or recovering from alcohol; craving; role impairment; social/interpersonal problems; giving up important activities; hazardous use; continued use despite physical/psychological problems; tolerance; and withdrawal. Each criterion is supported by the same DSM‑5 sources. 1, 2

The categorical label “alcoholic” is considered clinically unhelpful and stigmatizing; modern diagnostic frameworks replace “alcoholism,” “alcohol abuse,” and “alcohol dependence” with the unified, dimensional concept of Alcohol Use Disorder. 1, 4

Once AUD is established, severity is stratified by the number of criteria met:
- Mild AUD: 2–3 criteria 1, 2
- Moderate AUD: 4–5 criteria 1, 2
- Severe AUD: ≥6 criteria 1, 2

The Alcohol Use Disorders Identification Test (AUDIT) is the gold‑standard screening instrument, developed by the WHO in 1982 and demonstrated to have high sensitivity and specificity across diverse populations and clinical settings. 1, 5, 4
For rapid screening, the AUDIT‑C (consumption‑only items) uses gender‑specific cut‑offs: a score > 4 in men or > 3 in women is considered positive and warrants full AUDIT evaluation. 6

Do not base diagnosis solely on the quantity of alcohol consumed. Heavy drinking raises risk, but AUD diagnosis depends on the pattern of use and its adverse consequences, not merely volume. 1, 2
Physical dependence (tolerance or withdrawal) is not required for diagnosis. These represent only two of the eleven criteria; many individuals with clinically significant AUD do not exhibit tolerance or withdrawal. 1, 2
