The phenomenology of schizophrenia occurring in childhood.

Thirty-five children, aged 4 to 13 (X = 9.54), meeting strict DSM-III criteria for schizophrenia, are described. The subjects were diagnosed using a new semistructured interview. All were in the normal range of intelligence (mean IQ = 94) and free of neurological disorders. Characteristic auditory hallucinations were present in 80% and delusions in 63% of the sample. The mean age of onset of psychotic symptoms was 6.9 years. Premorbid histories of attention deficit, conduct disturbance and/or developmental abnormalities were common. The nature and content of psychotic symptoms varied with developmental stage. The phenomenological presentation of the sample was similar to previous studies of young schizophrenic children.
