Cohen, Ira L.; Liu, Xudong; Hudson, Melissa; Gillis, Jennifer; Cavalari, Rachel N. S.; Romanczyk, Raymond G.; Karmel, Bernard Z.; Gardner, Judith M. – Journal of Autism and Developmental Disorders, 2016
In order to improve discrimination accuracy between Autism Spectrum Disorder (ASD) and similar neurodevelopmental disorders, a data mining procedure, Classification and Regression Trees (CART), was used on a large multi-site sample of PDD Behavior Inventory (PDDBI) forms on children with and without ASD. Discrimination accuracy exceeded 80%,…

The New DSM-5 Impairment Criterion: A Challenge to Early Autism Spectrum Disorder Diagnosis?
Peer reviewed Peer reviewed
Direct linkDirect link
Zander, Eric; Bölte, Sven – Journal of Autism and Developmental Disorders, 2015
The possible effect of the DSM-5 impairment criterion on diagnosing autism spectrum disorder (ASD) in young children was examined in 127 children aged 20-47 months with a DSM-IV-TR clinical consensus diagnosis of ASD. The composite score of the Vineland Adaptive Behavior Scales (VABS) served as a proxy for the DSM-5 impairment criterion. When…

Bussu, G.; Jones, E. J. H.; Charman, T.; Johnson, M. H.; Buitelaar, J. K.; Baron-Cohen, S.; Bedford, R.; Bolton, P.; Blasi, A.; Chandler, S.; Cheung, C.; Davies, K.; Elsabbagh, M.; Fernandes, J.; Gammer, I.; Garwood, H.; Gliga, T.; Guiraud, J.; Hudry, K.; Liew, M.; Lloyd-Fox, S.; Maris, H.; O'Hara, L.; Pasco, G.; Pickles, A.; Ribeiro, H.; Salomone, E.; Tucker, L.; Volein, A. – Journal of Autism and Developmental Disorders, 2018
We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Reszka, Stephanie S.; Boyd, Brian A.; McBee, Matthew; Hume, Kara A.; Odom, Samuel L. – Journal of Autism and Developmental Disorders, 2014
The autism spectrum disorder (ASD) diagnostic classifications, according to the DSM-5, include a severity rating. Several screening and/or diagnostic measures, such as the autism diagnostic and observation schedule (ADOS), Childhood Autism Rating Scale (CARS) and social responsiveness scale (SRS) (teacher and parent versions), include an…

Subclassification of Children with Autism and Pervasive Developmental Disorders: A Questionnaire Based on Wing's Subgrouping Scheme.
Peer reviewed Peer reviewed
Castelloe, Paul; Dawson, Geraldine – Journal of Autism and Developmental Disorders, 1993
Forty parents of children with autism or pervasive developmental disorder completed the Wing Subgroups Questionnaire, developed for subclassifying children into one of L. Wing's three hypothesized subgroups. Results indicated that the questionnaire has adequate external criterion-referenced validity, with similar subgroup ratings made by…

Utility of the Gilliam Autism Rating Scale in Research and Clinical Populations.
Peer reviewed Peer reviewed
South, Mikle; Williams, Brenda J.; McMahon, William M.; Owley, Thomas; Filipek, Pauline A.; Shernoff, E.; Corsello, Christina; Lainhart, Janet E.; Landa, Rebecca; Ozonoff, Sally – Journal of Autism and Developmental Disorders, 2002
A study examined the validity of the Gilliam Autism Rating Scale (GARS) with 119 children (ages 3-10) with strict DSM-IV (Diagnostic Statistical Manual of Mental Disorders-IV) diagnoses of autism. The GARS consistently underestimated the likelihood that children would be classified as having autism. Limitations of ratings scales and of the GARS…

Toward a Developmental Operational Definition of Autism.
Peer reviewed Peer reviewed
Gillham, Jane E.; Carter, Alice S.; Volkmar, Fred R.; Sparrow, Sara S. – Journal of Autism and Developmental Disorders, 2000
Vineland Adaptive Behavior Scales scores and measures of intellectual functioning obtained for 44 children (ages 4-13) with autism, 21 with pervasive developmental disorder not otherwise specified, and 30 with developmental disorders, indicated autism and combined nonautism groups could be differentiated on socialization, daily living skills, and…

Empirically Derived Subclassification of the Autistic Syndrome.
Peer reviewed Peer reviewed
Siegel, Bryna; And Others – Journal of Autism and Developmental Disorders, 1986
A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…

Wetherby, Amy M.; Woods, Juliann; Allen, Lori; Cleary, Julie; Dickinson, Holly; Lord, Catherine – Journal of Autism and Developmental Disorders, 2004
Three groups of 18 children were selected for this study, one group with autism spectrum disorders (ASD), one group with developmental delays in which ASD was ruled out (DD), and one group with typical development (TD), from a pool of 3026 children who were screened with the Communication and Symbolic Behavior Scales Developmental Profile (CSBS…

Review of the Asperger Syndrome Diagnostic Scale.
Peer reviewed Peer reviewed
Goldstein, Sam – Journal of Autism and Developmental Disorders, 2002
The reliability, validity, and clinical utility of the Asperger Syndrome Diagnostic Scale in the diagnosis of pervasive developmental disorders are reviewed. While the measure holds promise as a research tool, there appears little evidence that it can distinguish among the variety of types of pervasive developmental disorders, or diagnose Asperger…

Signal Detection Analysis of Items from the Autism Behavior Checklist. Brief Report.
Peer reviewed Peer reviewed
Oswald, Donald P.; Volkmar, Fred R. – Journal of Autism and Developmental Disorders, 1991
Autism Behavior Checklists were completed for 52 autistic individuals (ages 2-31) and 62 nonautistic individuals, and data were analyzed using signal detection methodology. A single item (looks "through" people) combined with one of five other items discriminated as well as the sum scores, and further combinations did not improve…

A Closer Look at the Autism Behavior Checklist: Discriminant Validity and Factor Structure.
Peer reviewed Peer reviewed
Wadden, Norma P. K.; And Others – Journal of Autism and Developmental Disorders, 1991
The Autism Behavior Checklist was completed for 67 autistic and 56 mentally retarded and learning-disabled children (ages 6-15). The checklist was effective in classifying children when using either the full scale or only the more highly weighted items. Results did not support a single unidimensional scale or subdividing the checklist into five…
