Which symptom set comprises the diagnostic criteria for Schizophreniform Disorder?

• A. Delusions, Hallucinations, Disorganized speech, Negative symptoms
• B. Delusions, Obsessions, Compulsions, Mood swings
• C. Hallucinations, Anxiety, Depression, Sleep disturbance
• D. Grossly disorganized behavior, Catatonia, Anhedonia, Paranoia

Answer: (A)

The key idea is that schizophreniform disorder uses the same symptom pattern as schizophrenia: you need two or more of five core psychotic symptoms during a one-month period, and at least one of those must be delusions, hallucinations, or disorganized speech. The five symptoms are delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms (such as flat affect or avolition). The set that includes delusions, hallucinations, disorganized speech, and negative symptoms fits this framework, since it contains multiple items from the list and includes at least one of the mandatory features (delusions or hallucinations). This demonstrates the kind of symptom cluster that would support the diagnosis, provided the duration criteria are also met (symptoms lasting 1–6 months). The other options mix in features not defining the schizophrenia-spectrum criteria (like obsessive-compulsive symptoms, mood or anxiety symptoms, or non-core sleep issues), which don’t establish the diagnostic pattern by themselves.
