DSM-5 Substance Use Disorder Criteria: An Overview
Introduction to DSM-5 Substance Use Disorder Criteria
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), introduced significant changes to the criteria for diagnosing substance use disorders (SUDs). These changes were driven by extensive research and aimed to improve the reliability and validity of SUD diagnoses 125.
Combining Abuse and Dependence into a Single Disorder
One of the most notable changes in DSM-5 is the combination of the previously separate categories of substance abuse and substance dependence into a single diagnosis: substance use disorder. This decision was based on findings that abuse and dependence criteria represent a single underlying dimension of substance use severity 125. The new criteria set includes 11 symptoms, and a diagnosis is made if at least two of these symptoms are present 149.
Addition and Removal of Specific Criteria
Removal of Legal Problems
The DSM-5 criteria for SUDs no longer include legal problems as a diagnostic criterion. This change was supported by research indicating that the legal problems criterion had limited diagnostic utility and did not significantly contribute to the overall assessment of substance use severity 126.
Addition of Craving
Craving was added as a new criterion in DSM-5. Although there was some debate about its inclusion, craving was ultimately added due to its importance in the conceptualization of substance use disorders and its potential as a diagnostically useful biomarker 1257. However, some studies have shown mixed support for the addition of craving, suggesting that it may not significantly enhance the diagnostic process 249.
Introduction of Withdrawal Syndromes for Additional Substances
The DSM-5 also introduced withdrawal syndromes for cannabis and caffeine, aligning these substances with others that already had established withdrawal criteria. This change was made to provide a more comprehensive understanding of the withdrawal experiences associated with these substances .
Alignment of Tobacco Use Disorder Criteria
The criteria for tobacco use disorder were aligned with those for other substance use disorders, ensuring consistency across different types of substances. This alignment helps in providing a uniform approach to diagnosing and treating various substance use disorders .
Impact on Prevalence and Diagnosis
The changes in DSM-5 criteria have led to a modest increase in the prevalence of SUD diagnoses. This increase is largely due to the inclusion of individuals who were previously considered "diagnostic orphans" under DSM-IV, meaning they met one or two criteria for dependence but none for abuse . The new criteria set captures these individuals, providing a more inclusive and accurate diagnosis 49.
Reliability and Validity of DSM-5 SUD Diagnoses
Studies have shown that the DSM-5 criteria for SUDs are generally reliable and valid. Test-retest reliability for DSM-5 SUD diagnoses is substantial to excellent for most substances, indicating that the new criteria provide consistent and dependable diagnoses . The unidimensionality of the criteria set has been confirmed for various substances, supporting the validity of the combined diagnosis 268.
Conclusion
The DSM-5 criteria for substance use disorders represent a significant advancement in the diagnosis and understanding of SUDs. By combining abuse and dependence into a single disorder, removing less useful criteria, and adding new ones like craving, the DSM-5 provides a more comprehensive and reliable framework for diagnosing and treating substance use disorders. These changes are expected to improve clinical practice and research, although ongoing studies are needed to further refine and validate the criteria.
