Unformatted text preview: The DSM-IV: Selected diagnostic criteria for several Psychiatric disorders. NOTE: The DSM-IV-TR can be accessed free of charge via the Tisch website under ‘Databases and Articles’ as an e-book. You should refer to this for more complete descriptions. PSYCHOTIC DISORDERS Diagnostic criteria for Schizophrenia A. Characteristic symptoms: Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated): (1) delusions (2) hallucinations (3) disorganized speech (e.g., frequent derailment or incoherence) (4) grossly disorganized or catatonic behavior (5) 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.

During these prodromal or residual periods, the signs of the disturbance may be manifested by only negative symptoms or two or more symptoms listed in Criterion A present in an attenuated form (e.g., odd beliefs, unusual perceptual experiences).
