According to the material, what duration defines a brief psychotic disorder?

• A. Less than 1 month
• B. 1-2 months
• C. 2-6 months
• D. 6+ months

Answer: (A)

Brief psychotic disorder is defined by a sudden onset of one or more psychotic symptoms that lasts at least 1 day but less than 1 month, with full return to premorbid functioning. That duration boundary is why the correct choice is “less than 1 month.” If symptoms persist for longer, the diagnosis would shift to schizophreniform disorder (1–6 months) or schizophrenia (more than 6 months). An example: psychotic symptoms appear abruptly after a stressor and remit completely within a few weeks. This short, complete recovery differentiates it from longer-duration psychotic disorders.
