The classification of autism spectrum disorders (ASDs) is a topic of debate among clinicians and researchers with many questioning the validity of the distinction among subtypes. This manuscript examines the validity of three ASD subtypes (Autism, Asperger’s, and PDDNOS) by reviewing 22 studies published between 1994 and 2006. We reviewed studies that examined differences between the subtypes in terms of clinical and demographic characteristics, neuropsychological profiles, comorbidity, and… 

Categorical and Dimensional Structure of Autism Spectrum Disorders: The Nosologic Validity of Asperger Syndrome

The study provides evidence that AS and autism are not qualitatively distinct disorders, but rather different quantitative manifestations of the same disorder, and does not support the thesis that autistic disorders are discrete phenotypes.

Comparing Autism, PDD-NOS, and Other Developmental Disabilities on Parent-Reported Behavior Problems: Little Evidence for ASD Subtype Validity

Cognitive functioning may be a more salient variable than subtype when studying psychopathology in individuals with ASDs.

The relationship of cognitive profile to differential diagnosis of high-functioning autism and Asperger's Syndrome

The adequacy of diagnostic criteria for Asperger’s syndrome (AS) has been debated, and many in the field do not believe that AS warrants a discrete subgrouping, considering AS to differ from classic

Autism Spectrum Disorders and Intellectual Disability

This chapter discusses the impact of level of functioning on the presentation of ASDs and their associated features as well as the similarities and differences between the two disabilities in terms of psychopathology and adaptive behavior.

DSM-5 ASD Moves Forward into the Past

Findings do not support the conceptualization of AD, AsD and PDDNOS as a single category of ASD and future research and clinical practice will continue to find ways to meaningfully subtype the ASD.

It is suggested that quantitative measures of social reciprocity and repetitive behaviors and interests, with separate quantification of expressive language level and nonverbal intelligence, most accurately reflect the range of behavioral phenotypes in autism spectrum disorders.

Little difference was found between the three PDD subtypes with respect to EF and the view that executive dysfunctioning plays an important role in autism is supported.

Three Diagnostic Approaches to Asperger Syndrome: Implications for Research

Diagnostic assignments of AS based on three commonly used approaches have low agreement and lead to different results in comparisons of IQ profiles, patterns of comorbidity, and familial aggregation of psychiatric symptoms across the approach-specific resultant groups of HFA, AS, and PDD-NOS.

In this Norwegian population of children ages 3–14 years the minimum prevalence estimate for childhood autism was 4–5 per 10,000 using ICD-10 research criteria, and did not confirm the high estimates suggested more recently.

Can the Children's Communication Checklist differentiate autism spectrum subtypes?

The HFA cluster showed most autism characteristics, followed by the combined HFA + AS cluster, and then the PDD-NOS cluster, which support the autism spectrum concept based on severity of symptom impairment rather than distinct categories.

Annotation: The similarities and differences between autistic disorder and Asperger's disorder: a review of the empirical evidence.

There is currently insufficient evidence to establish the validity of Asperger's disorder as a syndrome distinct from high-functioning autism, and the findings are consistent with the view that these disorders belong on an autism spectrum.

An examination of the validity of social subtypes in Autism

The general findings supported the validity of aloof and active-but-odd subtypes as predictors of behavior across language/communication, reciprocal social interaction, and stereotyped behavior/restricted interest domains and suggested that individuals assigned to these respective groups differed in a number of important ways.

Reliability and accuracy of differentiating pervasive developmental disorder subtypes.

Although the psychometric properties of the current DSM-IV criteria for autism and AsD appear quite acceptable, there is likely to be a high rate of misclassification of children given a diagnosis of atypical autism.

Indications of a dissociation between verbal and visual-perceptual skills among the older children, and the specific association of discrepantly high nonverbal skills with increased social symptoms suggest that the nonverbal > verbal profile may index an etiologically significant subtype of autism.
