Alcohol Use Disorder Diagnosis and Classification

Diagnostic Criteria

The American Psychiatric Association recommends that Alcohol Use Disorder (AUD) be diagnosed based on the DSM-V criteria, which requires meeting at least two of eleven specific criteria within a 12-month period, with severity classified as mild, moderate, or severe 1
Consumption patterns, such as alcohol consumed in larger amounts or over longer periods than intended, are a key criterion for AUD diagnosis 2
Psychological and physical dependence, including craving or strong desire/urge to use alcohol, tolerance, and withdrawal symptoms, are also important criteria for AUD diagnosis 1, 2, 3
Social and functional impairment, such as recurrent alcohol use resulting in failure to fulfill major role obligations, continued use despite persistent/recurrent social or interpersonal problems, and important activities given up or reduced because of alcohol use, are critical criteria for AUD diagnosis 1, 2

The American Psychiatric Association classifies AUD severity as mild (2-3 criteria), moderate (4-5 criteria), or severe (6+ criteria) 1, 2

The World Health Organization recommends using the AUDIT (Alcohol Use Disorders Identification Test) as a gold standard screening tool to identify AUD, which is a 10-question assessment with high sensitivity and specificity 1, 4
The CAGE Questionnaire is a brief 4-question tool with 85% sensitivity and 89% specificity that asks about Cut-down attempts, Annoyance with criticism, Guilt feelings, and Eye-openers, and two or more "yes" responses indicate an alcohol use disorder 5, 2, 3
The AUDIT-C is a shortened 3-question version focusing on consumption patterns that maintains good sensitivity while requiring less time to administer 5

The prevalence of AUD has increased by 50% between 2001 and 2013, with greater increases among women, minorities, and those of lower socioeconomic status 5

The DSM-V concept of AUD represents an important advancement over previous categorical distinctions between alcohol abuse and dependence, recognizing varying levels of severity rather than the arbitrary distinction of who is or isn't an "alcoholic" 1

The term "alcoholic" can be stigmatizing and should be avoided in favor of the clinical diagnosis of AUD 1
AUD frequently co-occurs with other psychiatric conditions that may complicate diagnosis and treatment 5

The American Psychiatric Association’s DSM‑5 replaced the term “alcohol dependence” with the broader diagnosis of Alcohol Use Disorder (AUD), removing the separate “abuse” category and introducing a dimensional severity spectrum. 6
The World Health Organization’s ICD‑10 continues to list “alcohol dependence” as a distinct diagnostic category separate from hazardous and harmful alcohol use, although ICD‑11 revisions are under review. 7

AUD is diagnosed when an individual meets at least two of eleven criteria within a 12‑month period. 6
Example criteria supported by citation:
- Consuming alcohol in larger amounts or over longer periods than intended. 6
- Persistent desire or unsuccessful attempts to cut down drinking. 6
- Spending a great deal of time obtaining, using, or recovering from alcohol. 6
- Experiencing craving or a strong urge to use alcohol. 6
- Recurrent use leading to failure to fulfill major role obligations (e.g., work, school, home). 6
- Continuing use despite awareness of physical or psychological problems caused by alcohol. 7
Severity is classified by the number of criteria met: mild (2‑3 criteria), moderate (4‑5 criteria), severe (6 or more criteria). 6

The WHO maintains “alcohol dependence” as a separate diagnostic entity from harmful use, reflecting the traditional dependence‑syndrome concept that includes physiological and behavioral components. 7

The World Health Organization’s Alcohol Use Disorders Identification Test (AUDIT) is the gold‑standard screening instrument, developed in 1982 and demonstrated to have high sensitivity and specificity across diverse international populations. 6

The term “alcoholic” is discouraged because it is stigmatizing; clinicians should use the clinical diagnoses of Alcohol Use Disorder or alcohol dependence instead. 7
