What proportion of individuals will change to schizophrenia, affective disorder, or other psychotic disorder?

• A. More than 50% will change to schizophrenia, affective disorder, or other psychotic disorder
• B. Less than 50% will change to schizophrenia, affective disorder, or other psychotic disorder
• C. Prodromal/Residual Periods in Schizophrenia
• D. Symptoms of Schizophrenia

Answer: (B)

The question tests the idea that conversion from prodromal or attenuated psychosis states to a full psychotic disorder is not guaranteed and is relatively unlikely to reach the level of a majority. In people identified as at clinical high risk for psychosis, the chance of developing schizophrenia or another psychotic disorder within the next few years is substantial but typically falls well below 50%—roughly a minority to about a one-in-three range over 2–3 years, with some additional risk extending over longer periods. So saying that less than half will convert is the best answer. The other options describe phases or symptoms rather than a proportion of who will convert, so they don’t address the question about likelihood of progression. This concept matters because early identification and intervention aim to reduce the risk of conversion and improve outcomes.
