title: Symptoms in the first two years of life. A preliminary population study of infantile autism.
abstract: A population sample of autistic children (n = 26) were compared retrospectively with age- and sex-matched mentally retarded children (n = 20) and age- and sex-matched population-representative children (n = 25) on a 130-item questionnaire to the mother concerning characteristic features of the child's behaviour in the first 2 years of life. Thirteen items discriminated clearly between the groups. The results are discussed in the context of early screening for autism.
