What duration range is used to define schizophreniform disorder in the material?

• A. 2-6 months
• B. Less than 1 month
• C. 6+ months
• D. 1-2 months

Answer: (A)

Schizophreniform disorder is diagnosed when psychotic symptoms resemble schizophrenia but the illness hasn’t been present long enough to be called schizophrenia. The duration criterion helps separate it from brief psychotic disorder (symptoms for less than a month) and from schizophrenia (symptoms lasting six months or longer). In the material you’re studying, the specified window is two to six months, meaning the symptoms must be present for at least two months but no longer than six months for this diagnosis. This timeframe captures cases that follow a schizophrenia-like course without the prolonged duration that defines schizophrenia; if symptoms continue beyond six months, the diagnosis would typically shift to schizophrenia, whereas if they remit before two months, a brief psychotic disorder would be considered instead.
