In schizophreniform disorder, what proportion of cases will eventually be diagnosed with schizophrenia?

• A. About two-thirds will eventually be diagnosed with schizophrenia
• B. Most recover completely within 3 months
• C. All cases progress to schizophrenia
• D. None progress beyond 6 months

Answer: (A)

This question is about prognosis and how schizophreniform disorder can evolve into schizophrenia. Schizophreniform disorder lasts between 1 and 6 months, and if symptoms persist beyond 6 months, the diagnosis typically becomes schizophrenia. Across studies, about two-thirds of people diagnosed with schizophreniform disorder eventually meet criteria for schizophrenia, so roughly 66%. The remaining third may remit or have other outcomes, but not all patients convert, and it’s not accurate to say none progress or that all do.
