Schizophreniform Disorder lasts 1-6 months.

• A. 1-6 months
• B. 6-12 months
• C. 1 year or longer
• D. Less than 1 month

Answer: (A)

The key idea is how long psychotic symptoms must persist to qualify for this diagnosis. Schizophreniform disorder sits between brief psychotic disorder and schizophrenia timewise: you must have symptoms typical of schizophrenia for at least one month, but they cannot continue beyond six months. That places the appropriate duration squarely in the 1-6 month window. If symptoms last less than a month, the diagnosis would be brief psychotic disorder; if they last six months or more, the diagnosis would be schizophrenia. So the 1-6 months option is the correct fit.
