Which diagnostic criteria specify a duration of 6 months with at least 1 month of active-phase symptoms?

• A. DSM-5-TR diagnostic criteria
• B. ICD-11 criteria
• C. RDoC framework
• D. DSM-5-TR specifiers

Answer: (B)

Duration criteria for diagnosing schizophrenia require that symptoms persist for at least six months, with at least one month of active-phase symptoms (such as delusions, hallucinations, disorganized speech, disorganized or catatonic behavior, or negative symptoms). ICD-11 explicitly states this six-month threshold and the minimum one month of active-phase symptoms in its diagnostic criteria, which is why it aligns with what the question asks. The other options don’t specify this exact duration threshold in the same way: RDoC is a research framework, DSM-5-TR criteria also use a similar duration but the item points to ICD-11’s explicit wording, and DSM-5-TR specifiers describe course features rather than setting the duration requirement.
