An Examination of the Validity of Social Subtypes in Autism.
Peer reviewed Peer reviewed
Borden, M. Christopher; Ollendick, Thomas H. – Journal of Autism and Developmental Disorders, 1994
Examination of 53 children with autism supported the validity of the subtypes "aloof" and "active-but-odd" as predictors of behavior across language/communication, reciprocal social interaction, and stereotyped behavior/restricted interest domains. Partial support for an intermediate, "passive" subtype was garnered. (Author/JDD)
