What proportion of people with schizophreniform disorder are eventually diagnosed with schizophrenia?

• A. 1/3
• B. 1/2
• C. 0
• D. 2/3

Answer: (D)

Schizophreniform disorder represents a psychotic episode of intermediate duration—1 to 6 months. The key idea is prognosis: if the symptoms extend beyond six months, the diagnosis shifts to schizophrenia. Long-term follow-up data show that a substantial portion of those with schizophreniform disorder eventually meet criteria for schizophrenia—about two-thirds. The remaining roughly one-third may fully remit or evolve into other psychotic or mood-related disorders rather than schizophrenia. This pattern reflects how this condition often serves as a precursor to the more chronic course seen in schizophrenia.
