Behavioral characteristics of 187 young adults with autism

A survey was conducted on the present behavioral characteristics of 187 cases of adult autism in patients over 18␣years of age employing Achenbach's Child Behavior Checklist (CBCL). When their behavioral characteristics were evaluated in relation to Present Language Developmental Level (PLDL) and Present Adaptive Level (PAL), it was seen that greater variation in behavior characteristics was seen among those exhibiting increasingly lower PLDL and PAL scores. Behavior characteristics reminiscent of depression were noted even among those exhibiting high PLDL. Behavior pointing to obsession was found in common among almost all cases of autism irrespective of PLDL or PAL. Psychotic symptoms such as hallucinations and delusions were absent in most cases. The results of the present study were indicative not only of the significance of obsessive behavior in autism, but also its significance in terms of delving further into the psychopathology of the disorder.
