Are there subgroups within the autistic spectrum? A cluster analysis of a group of children with autistic spectrum disorders

Article Abstract:

Research has not been able to unearth definitive differences between the subgroups of pervasive developmental disorders (PDD) which include autism, Asperger's syndrome and pervasive developmental disorder not otherwise specified (PDD-NOS). Empirical clustering methods were used to analyze reported symptoms and behaviors of a large sample of children diagnosed with autism, Asperger's syndrome or other autistic-type disorders and evaluate the influence of age and verbal abilities on identified patterns. The results and implications are discussed.
