What duration is used to define schizophrenia in the material?

• A. 6+ months
• B. 1-6 months
• C. 2-6 months
• D. 1 month or more

Answer: (A)

Schizophrenia is defined by a duration of disturbance lasting six months or longer, with at least one month of active psychotic symptoms (delusions, hallucinations, disorganized speech). The total six-month span can include prodromal or residual periods when symptoms are less prominent. This duration requirement helps separate schizophrenia from disorders with shorter courses, such as schizophreniform disorder (about 1–6 months) or brief psychotic disorders (<1 month). So the duration used to define schizophrenia is six months or more.
