What term describes the minimum duration of symptoms required for a schizophrenia diagnosis?

• A. Prodromal/Residual Periods in Schizophrenia
• B. Duration for Schizophrenia Diagnosis
• C. Symptoms of Schizophrenia
• D. Relapse in Brief Psychotic Disorder

Answer: (B)

The concept being tested is the duration criterion for schizophrenia. Diagnosing schizophrenia isn’t just about which symptoms appear, but also how long they have been present. According to DSM-5, there must be continuous signs of disturbance for at least six months, and within that period at least one month of active-phase symptoms (such as delusions, hallucinations, or disorganized speech). Prodromal or residual periods may occur before or after the active phase, but they still count toward that overall duration. This time threshold distinguishes schizophrenia from disorders with briefer courses. The other choices either describe phases (prodromal/residual), general symptom lists, or unrelated conditions, and they don’t capture the required minimum duration.
