A good prognostic feature in schizophreniform disorder includes onset of psychotic symptoms within what time frame of first noticeable change in behavior?

• A. Within 4 weeks
• B. Within 8 weeks
• C. Within 6 months
• D. Within 1 year

Answer: (A)

A quick, abrupt onset of psychotic symptoms within a short window after the first noticeable change in behavior is a favorable prognostic sign in schizophreniform disorder. Specifically, onset within four weeks suggests a more acute, potentially reversible course and a better chance of improvement, compared with slower development over several weeks to months. Schizophreniform disorder requires symptoms for 1 month up to less than 6 months, so rapid onset within 4 weeks aligns with a better prognosis. Onset within 8 weeks or longer implies a slower progression and does not carry the same positive outlook, while onset framed around 6 months or 1 year would push the course toward the boundary with schizophrenia rather than schizopheniform disorder.
