The aim of the present study was to establish diagnostic validity of the new algorithm of the Autism Diagnostic Observation Scale, the ADOS-2, to differentiate between ASD and other clinically relevant psychiatric and developmental disorders in a large German sample. Validity of ADOS and ADOS-2 diagnostic algorithms was established in 826…

Stevenson, Jennifer L.; Hart, Kari R. – Journal of Autism and Developmental Disorders, 2017
The current study systematically investigated the effects of scoring and categorization methods on the psychometric properties of the Autism-Spectrum Quotient. Four hundred and three college students completed the Autism-Spectrum Quotient at least once. Total scores on the Autism-Spectrum Quotient had acceptable internal consistency and…

Harrison, Ashley J.; Bradshaw, Laine P.; Naqvi, Nilofer C.; Paff, Madison L.; Campbell, Jonathan M. – Journal of Autism and Developmental Disorders, 2017
ASD knowledge deficits contribute to disparities in the timing and quality of ASD services. To address the limitations with existing measures of ASD knowledge, we developed and examined the Autism Stigma and Knowledge Questionnaire (ASK-Q), which comprehensively assesses multiple subdomains of ASD knowledge while maintaining strong psychometric…

Duvekot, Jorieke; van der Ende, Jan; Verhulst, Frank C.; Greaves-Lord, Kirstin – Journal of Autism and Developmental Disorders, 2015
The screening accuracy of the parent and teacher-reported Social Responsiveness Scale (SRS) was compared with an autism spectrum disorder (ASD) classification according to (1) the Developmental, Dimensional, and Diagnostic Interview (3Di), (2) the Autism Diagnostic Observation Schedule (ADOS), (3) both the 3Di and ADOS, in 186 children referred to…

Booth, Tom; Murray, Aja Louise; McKenzie, Karen; Kuenssberg, Renate; O'Donnell, Michael; Burnett, Hollie – Journal of Autism and Developmental Disorders, 2013
There is a need for brief screening instruments for autistic spectrum disorders (ASD) that can be used by frontline healthcare professionals to aid in the decision as to whether an individual should be referred for a full diagnostic assessment. In this study we evaluated the ability of a short form of the autism spectrum quotient (AQ)…

The algorithm of the Autism Diagnostic Interview-Revised provides criteria for autism versus non-autism according to DSM-IV. Criteria for the broader autism spectrum disorders are needed. This study investigated the validity of seven sets of criteria from the literature, in 1,204 Dutch children (aged 3-18 years) with and without mental…

de Bildt, Annelies; Mulder, Erik J.; Hoekstra, Pieter J.; van Lang, Natasja D. J.; Minderaa, Ruud B.; Hartman, Catharina A. – Journal of Autism and Developmental Disorders, 2009
The Children's Social Behavior Questionnaire (CSBQ) was compared with the Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule (ADOS), and clinical classification in children with mild and moderate intellectual disability (ID), to investigate its criterion related validity. The contribution of the CSBQ to a…

Reliability and validity for three autism instruments were compared for 190 children with low functioning autism (LFA), 190 children with high functioning autism or Asperger's disorder (HFA), 76 children with attention deficit hyperactivity disorder (ADHD), and 64 typical children. The instruments were the Checklist for Autism Spectrum Disorder…

Sikora, Darryn M.; Hall, Trevor A.; Hartley, Sigan L.; Gerrard-Morris, Aimee E.; Cagle, Sarah – Journal of Autism and Developmental Disorders, 2008
Behavior checklists are often utilized to screen for Autism Spectrum Disorders (ASDs) when comprehensive evaluations are unfeasible. The usefulness of two behavioral checklists, the Gilliam Autism Rating Scale (GARS) and Child Behavior Checklist (CBCL), in identifying ASDs was investigated among 109 children with Autism, 32 children with ASD, and…

Tomanik, Stacey S.; Pearson, Deborah A.; Loveland, Katherine A.; Lane, David M.; Shaw, J. Bryant – Journal of Autism and Developmental Disorders, 2007
The classification agreement of the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) was examined in 129 children and adolescents (aged 7-18 years) who were evaluated for autism. Participants received a diagnosis of autism or non-autism based on the ADI-R. Linear discriminant analysis revealed…

This study compared DSM-III-R (Diagnostic and Statistical Manual III, Revised), Childhood Autism Rating Scale, and clinical diagnoses of 138 admissions to a program for diagnosis and treatment of autistic and related communication-handicapped individuals. Results indicated generally high agreement on the diagnosis of autism, with DSM-III-R…

Peer reviewedGhaziuddin, Mohammad; And Others – Journal of Autism and Developmental Disorders, 1992
This paper assesses to what extent the ICD-10 (International Classification of Diseases) criteria differ from other diagnostic systems for Asperger syndrome. The paper concludes that the variety of criteria in use makes interpretation of research findings difficult and that the ICD-10 criteria are the most stringent and closest to Hans Asperger's…

This paper compared clinicians' diagnosis and DSM-III (Diagnostic and Statistical Manual), DSM-III-R (Revised), and ICD-10 (International Classification of Diseases) diagnoses of 52 individuals with autism and 62 nonautistic, developmentally disordered individuals. The DSM-III-R system overdiagnosed the presence of autism, and ICD-10 closely…

An evaluation was made of the empirical validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) with 51 individuals with severe/profound mental retardation, some of whom were also diagnosed with autism, and controls. The Autism/Pervasive Developmental Disorder subscale of the DASH-II was internally consistent and just as…

Describes the development of the Children's Social Behavior Questionnaire (CSBQ), an instrument designed to provide an extensive list of behaviors frequently observed in children with Pervasive Developmental Disorder Not Otherwise Specified. The successful results of the CSBQ in distinguishing the characteristics of this disability are reported.…
