Schizophreniform Disorder Symptoms
The formal diagnosis of schizophreniform disorder rests on these symptoms, which can be evaluated by psychiatrists and other mental health professionals.
Symptoms of Schizophreniform Disorder
The following specific diagnostic criteria are reproduced verbatim (except for codings and page references) from the DSM-IV, the immediate predessor of the current DSM-IV TR (where ‘IV TR’ indicates fourth edition, text revision).
Diagnostic Criteria for Schizophreniform Disorder
A. Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated):
- disorganized speech (e.g., frequent derailment or incoherence)
- grossly disorganized or catatonic behavior
- negative symptoms, i.e., affective flattening, alogia, or avolition
Note: Only one Criterion A symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person’s behavior or thoughts, or two or more voices conversing with each other.

D. An episode of the disorder (including prodromal, active, and residual phases) lasts at least 1 month but less than 6 months. (When the diagnosis must be made without waiting for recovery, it should be qualified as “Provisional.”)
