Classification of alcohol use disorders.

Area of Science:

• Psychiatry
• Addiction Medicine
• Epidemiology

Background:

• Accurate definitions of medical conditions are crucial for research and clinical practice.
• The Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD) provide widely used definitions for alcohol use disorders.
• These definitions are fundamental to alcoholism research, including treatment studies, genetics, and epidemiology.

Purpose of the Study:

• To evaluate the reliability and validity of current diagnostic criteria for alcohol use disorders.
• To assess the performance of definitions from the DSM and ICD in research and clinical settings.

Main Methods:

• Review of existing studies on the reliability and validity of DSM and ICD diagnostic criteria for alcohol use disorders.
• Analysis of reliability data for alcohol dependence and alcohol abuse/harmful use.
• Analysis of validity data for alcohol dependence and alcohol abuse/harmful use.

Main Results:

• High reliability was consistently observed for DSM-IV and ICD-10 alcohol dependence diagnoses.
• Lower reliability was found for alcohol abuse/harmful use criteria.
• Validity studies indicated good validity for alcohol dependence diagnoses.
• The validity of alcohol abuse/harmful use diagnoses was significantly lower.

Conclusions:

• DSM-IV and ICD-10 criteria demonstrate strong reliability and validity for alcohol dependence.
• Alcohol abuse/harmful use criteria exhibit notable reliability and validity issues.
• The hierarchical structure of alcohol abuse in relation to dependence may underlie these diagnostic challenges.
