Within what time frame must the 2+ DSM-5 criteria occur to diagnose substance use disorder?

• A. Within 3 months
• B. Within 6 months
• C. Within 9 months
• D. Within 12 months

Answer: (D)

The key idea is how DSM-5 defines when substance use disorder is diagnosed: at least two criteria must be present within a 12-month period. This year-long window is designed to capture a pattern of problematic use over time, not just a single incident. If two or more criteria occur within any 12-month span, the diagnosis is made, with the number of criteria guiding severity. Shorter windows (like 3, 6, or 9 months) don’t define the diagnosis on their own because the standard reference is a 12-month period.
