What is the primary purpose of DSM-5-TR criteria in substance use disorders?

• A. To determine if SUD criteria are met, assign severity, and guide treatment planning.
• B. To determine the cost of treatment.
• C. To classify criminal responsibility in substance use cases.
• D. To evaluate the risk of harm to others.

Answer: (A)

The DSM-5-TR criteria are used to diagnose Substance Use Disorders by checking whether a pattern of problematic use meets specific criteria over the past year, and to rate that disorder as mild, moderate, or severe based on how many criteria are met. This standardized diagnosis guides treatment planning because the level of severity informs the intensity and type of intervention, targets to address (such as reducing use, managing withdrawal, or improving functioning), and how progress will be tracked over time. It’s not about estimating treatment costs, determining criminal responsibility, or assessing risk to others, which are separate considerations outside the diagnostic framework.
