Assessing functioning of children on the autism spectrum is necessary to determine the level of support they require to participate in everyday activities across contexts. The International Classification of Functioning, Disability and Health (ICF) is a comprehensive biopsychosocial framework recommended for classifying health-related functioning…

Lai, Kelly Y. C.; Yuen, Emily C. W.; Hung, Se Fong; Leung, Patrick W. L. – Journal of Autism and Developmental Disorders, 2022
This study examines the psychometric properties of the Autism Diagnostic Interview-Revised (ADI-R) in the context of DSM-5 in a sample of Chinese children. Using re-mapped ADI-R items and algorithms matched to DSM-5 criteria, and administering to children with autism spectrum disorder (ASD) with and without intellectual disability,…

Mukherjee, Sharmila B.; Neelam; Kapoor, Seema; Sharma, Suvasini – Journal of Autism and Developmental Disorders, 2021
The Autism Dysmorphology Measure is designed for non-expert clinicians. It uses an algorithm to assess 12 body regions and categorizes Autism on the number of dysmorphic regions identified; Essential ([less than or equal to] 3), Equivocal (4-5) or Complex ([greater than or equal to] 6). We evaluated 200 Indian children with Autism (mean age…

Sung, Min; Goh, Tze Jui; Tan, Bei Lin Joelene; Chan, Jialei Stephanie; Liew, Hwee Sen Alvin – Journal of Autism and Developmental Disorders, 2018
Our study examines the Diagnostic and Statistical Manual--Fifth Edition (DSM-5) and Diagnostic and Statistical Manual--Fourth Edition, Text Revision (DSM-IV-TR) when applied concurrently against the best estimate clinical diagnoses for 110 children (5.1-19.6 years old) referred for diagnostic assessments of Autism Spectrum Disorder (ASD) in a…

Henry, Lucy A.; Crane, Laura; Nash, Gilly; Hobson, Zoe; Kirke-Smith, Mimi; Wilcock, Rachel – Journal of Autism and Developmental Disorders, 2017
Three promising investigative interview interventions were assessed in 270 children (age 6-11 years): 71 with autism spectrum disorder (ASD) and 199 who were typically developing (TD). Children received "Verbal Labels," "Sketch Reinstatement of Context" or "Registered Intermediary" interviews designed to improve…

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…

Wong, Virginia C. N.; Fung, Cecilia K. Y.; Wong, Polly T. Y. – Journal of Autism and Developmental Disorders, 2014
Data from 1,261 Chinese Autistic Spectrum Disorder (ASD) patients were evaluated and categorized into dysmorphic (10.79%) and non-dysmorphic groups (89.21%) upon physical examination by the presence of dysmorphic features. Abnormal MRI/CT result, IQ scores and epilepsy were significantly associated with the dysmorphic group of ASD children.…

Ruta, Liliana; Mazzone, Domenico; Mazzone, Luigi; Wheelwright, Sally; Baron-Cohen, Simon – Journal of Autism and Developmental Disorders, 2012
The Autism Spectrum Quotient (AQ) has been used to define the "broader" (BAP), "medium" (MAP) and "narrow" autism phenotypes (NAP). We used a new Italian version of the AQ to test if difference on AQ scores and the distribution of BAP, MAP and NAP in autism parents (n = 245) versus control parents (n = 300) were…

Lauritsen, Marlene B.; Jorgensen, Meta; Madsen, Kreesten M.; Lemcke, Sanne; Toft, Susanne; Grove, Jakob; Schendel, Diana E.; Thorsen, Poul – Journal of Autism and Developmental Disorders, 2010
The purpose of this study was to assess the validity of the diagnosis of childhood autism in the Danish Psychiatric Central Register (DPCR) by reviewing medical records from 499 of 504 total children with childhood autism born 1990-1999. Based on review of abstracted behaviors recorded in case records from child psychiatric hospitals, case status…

Parner, Erik T.; Thorsen, Poul; Dixon, Glenys; de Klerk, Nicholas; Leonard, Helen; Nassar, Natasha; Bourke, Jenny; Bower, Carol; Glasson, Emma J. – Journal of Autism and Developmental Disorders, 2011
Prevalence statistics for autism spectrum disorders (ASD) vary widely across geographical boundaries. Some variation can be explained by diagnostic methods, case ascertainment and age at diagnosis. This study compared prevalence statistics for two distinct geographical regions, Denmark and Western Australia, both of which have had population-based…

de Bildt, Annelies; Sytema, Sjoerd; van Lang, Natasja D. J.; Minderaa, Ruud B.; van Engeland, Herman; de Jonge, Maretha V. – Journal of Autism and Developmental Disorders, 2009
The revised ADOS algorithms, proposed by Gotham et al. (J Autism Dev Disord 37:613-627, 2007), were investigated in an independent sample of 558 Dutch children (modules 1, 2 and 3). The revised algorithms lead to better balanced sensitivity and specificity for modules 2 and 3, without losing efficiency of the classification. Including the…

Coo, Helen; Ouellette-Kuntz, Helene; Lloyd, Jennifer E. V.; Kasmara, Liza; Holden, Jeanette J. A.; Lewis, M. E. Suzanne – Journal of Autism and Developmental Disorders, 2008
There has been little evidence to support the hypothesis that diagnostic substitution may contribute to increases in the administrative prevalence of autism. We examined trends in assignment of special education codes to British Columbia (BC) school children who had an autism code in at least 1 year between 1996 and 2004, inclusive. The proportion…

Kraijer, Dirk; de Bildt, Annelies – Journal of Autism and Developmental Disorders, 2005
The Scale of Pervasive Developmental Disorder in Mentally Retarded Persons (PDD-MRS) is described. The PDD-MRS is a simple classification and screening instrument devised for identification of autistic disorders (of the entire spectrum) in persons with mental retardation from mild to profound levels, age-range 2-55 years. The norms of the scale…
