For Substance/Med Induced Psychotic Disorder, there must be evidence that delusions or hallucinations developed after exposure to a substance.

• A. Not necessary
• B. Before exposure to any substance
• C. During a period of sustained remission
• D. After intoxication or withdrawal from a substance capable of producing them

Answer: (D)

The key idea is that psychotic symptoms must be directly tied to the substance's effects, appearing after exposure. In Substance/Medication-Induced Psychotic Disorder, delusions or hallucinations arise due to the physiological impact of the substance and occur during intoxication or withdrawal. That’s why the correct choice specifies symptoms that emerge after intoxication or withdrawal from a substance capable of producing them. If symptoms started before exposure, or only occur during remission, or persist independently of the substance’s effects, the presentation wouldn’t fit this diagnosis. The diagnosis hinges on a clear temporal relationship to substance use and the expectation that symptoms are linked to the substance’s active use or withdrawal.
