In schizophreniform disorder, what proportion of individuals are eventually diagnosed with schizophrenia?

• A. 1/3 recover within 6 months
• B. 1/2 recover within 6 months
• C. 0
• D. 2/3 eventually diagnosed with schizophrenia

Answer: (D)

Schizophreniform disorder is a schizophrenia-spectrum condition characterized by psychotic symptoms that last between 1 and 6 months. Because it sits between brief psychotic disorder and schizophrenia, many individuals either remit or progress to a more persistent illness. Longitudinal data show that roughly two-thirds (about 66%) of people diagnosed with schizophreniform disorder later meet criteria for schizophrenia or another chronic schizophrenia-spectrum disorder. The remaining third tend to recover within that 1–6 month window or transition to other, less typical outcomes. So the proportion that eventually develops schizophrenia is best described as about two-thirds.
