Note: the APA did not publish separate criteria for autism until 1980
DSM I (1952)
000-x28 Schizophrenic reaction, childhood type
Here will be classified those schizophrenic reactions occurring before puberty. The clinical picture may differ from schizophrenic reactions occurring in other age periods because of the immaturity and plasticity of the patient at the time of onset of the reaction. Psychotic reactions in children, manifesting primarily autism, will be classified here.
DSM II (1968)
[autism was not mentioned; the word appears only under the following category]
295.8 Schizophrenia, childhood type
This category is for cases in which schizophrenic symptoms appear before puberty. The condition may be manifested by autistic, atypical and withdrawn behavior; failure to develop identity separate from the mother's; and general unevenness, gross immaturity and inadequacy of development. These developmental defects may result in mental retardation, which should also be diagnosed.
