Evidence that delusions/hallucinations developed after intoxication or withdrawal from a substance capable of producing them.

• A. Substance/Med Induced Psychotic Disorder
• B. Schizoaffective Disorder
• C. Mood Disorder with Psychotic Features
• D. Diagnosis Criteria for Substance/Med Induced Psychotic Disorder

Answer: (D)

The key idea is that the timing of psychotic symptoms in relation to substance exposure defines the diagnosis. When delusions or hallucinations arise during intoxication or shortly after withdrawal from a substance capable of producing them, that evidence fits the diagnostic criteria for Substance/Med Induced Psychotic Disorder rather than naming a primary psychotic illness. The option referencing the criteria captures the exact requirement that the psychotic symptoms must be temporally linked to substance exposure. Other choices describe disorder labels that imply different etiologies or patterns of psychosis, not the timing-based criterion used to diagnose substance/medication–induced psychosis.
