What is the minimum duration for a schizophrenia diagnosis in most criteria?

• A. 1-6 months
• B. More than 6 months
• C. 3 months
• D. 12 months

Answer: (B)

Schizophrenia is diagnosed when there is a sustained disturbance in thinking, perception, or behavior over a long period, specifically lasting at least six months. This total duration includes any prodromal or residual phases plus the active illness, and the active symptoms (such as delusions, hallucinations, or disorganized speech) must persist for at least one month. Because the threshold is six months or longer, the minimum duration used in most criteria points to about six months, making that time frame the key requirement. Shorter periods aren’t sufficient to meet the diagnosis.
