Brief Report: Are ADHD Traits Dissociable from the Autistic Profile? Links Between Cognition and Behaviour / Catherine S. AMES in Journal of Autism and Developmental Disorders, 41-3 (March 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-3 (March 2011) . - p.357-363 Titre : Brief Report: Are ADHD Traits Dissociable from the Autistic Profile? Links Between Cognition and Behaviour Type de document : Texte imprimé et/ou numérique Auteurs : Catherine S. AMES, Auteur ; Sarah J. WHITE, Auteur Année de publication : 2011 Article en page(s) : p.357-363 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Attention deficit hyperactivity disorder  Social cognition  Executive function  Theory of mind Index. décimale : PER Périodiques Résumé : Reports of co-morbid symptoms of ADHD in children with ASD have increased. This research sought to identify ADHD-related behaviours in a sample of children with ASD, and their relationship with the ASD triad of impairments and related cognitive impairments. Children with ASD (n = 55) completed a comprehensive cognitive assessment whilst a semi-structured parental interview (3Di) provided information on ASD and ADHD symptoms. Co-morbid presentation of ADHD traits in these participants was associated with reports of more ASD related behaviours. Inhibitory control performance was directly related only to the ADHD symptom of impulsive behaviour. In contrast, while there was a relationship between social difficulties associated with ASD and theory of mind ability, there was no such relationship with behaviours relating to ADHD.

Exploring anxiety symptoms in a large-scale twin study of children with autism spectrum disorders, their co-twins and controls / Victoria HALLETT in Journal of Child Psychology and Psychiatry, 54-11 (November 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-11 (November 2013) . - p.1176-1185 Titre : Exploring anxiety symptoms in a large-scale twin study of children with autism spectrum disorders, their co-twins and controls Type de document : Texte imprimé et/ou numérique Auteurs : Victoria HALLETT, Auteur ; Angelica RONALD, Auteur ; Emma COLVERT, Auteur ; Catherine S. AMES, Auteur ; Emma WOODHOUSE, Auteur ; Stephanie LIETZ, Auteur ; Tracy GARNETT, Auteur ; Nicola GILLAN, Auteur ; Frühling V. RIJSDIJK, Auteur ; Lawrence SCAHILL, Auteur ; Patrick BOLTON, Auteur ; Francesca HAPPE, Auteur Article en page(s) : p.1176-1185 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  anxiety  twin  siblings  comorbidity Index. décimale : PER Périodiques Résumé : Background Although many children with autism spectrum disorders (ASDs) experience difficulties with anxiety, the manifestation of these difficulties remains unresolved. The current study assessed anxiety in a large population-based twin sample, aged 10–15 years. Phenotypic analyses were used to explore anxiety symptoms in children with ASDs, their unaffected co-twins and a control sample. Methods Participants included 146 families from the Twins Early Development Study (TEDS) where one or both children had a suspected ASD. Eighty control families were also included. The Revised Child Anxiety and Depression scale (Chorpita, Yim, Moffitt, Umemoto Francis, 2000) was completed (self- and parent-report), along with diagnostic and cognitive tests. Children were categorized into four groups (a) ASD (b) Broader Autism Phenotype (BAP: mainly co-twins of children with ASDs, with high subclinical autistic traits) (c) unaffected co-twins (with neither ASDs nor BAP) (d) controls. Results Children in the ASD and BAP groups scored significantly higher than controls for all parent-rated (although not child-rated) anxiety subscales. There were no significant differences between the ASD and BAP groups for any of the parent-rated anxiety subscales. Compared with controls, unaffected co-twins showed significantly heightened Social Anxiety, Generalized Anxiety, and Panic symptoms. Significant associations were observed between certain anxiety subscales and both IQ and ASD symptoms. For example, greater parent-rated Social Anxiety was associated with higher IQ and increased social and communicative impairments. Significant interrater correlations were observed for anxiety reports in children with ASDs (r = .27–.54; p .01), their unaffected co-twins (r = .32–.63; p .01) and controls (r = .23–.43; p .01) suggesting that children in this sample with and without ASD symptoms were able to report on their anxiety symptoms with some accuracy. Conclusions These findings support previous reports of heightened anxiety in children with ASDs, at least on parent-reported measures. Unaffected co-twins of children with ASDs also showed increased anxiety, generating questions about the potential etiological overlap between ASDs and anxiety. Progress in this area now depends on more refined anxiety measurement in ASDs and continued investigation of interrater differences.

Exploring the cognitive features in children with autism spectrum disorder, their co-twins, and typically developing children within a population-based sample / Victoria E. A. BRUNSDON in Journal of Child Psychology and Psychiatry, 56-8 (August 2015)

The findings in the literature are somewhat mixed regarding the cognitive features of ASD. This study attempted to address this issue by investigating a range of cognitive deficits and the prevalence of multiple cognitive atypicalities in a large population-based sample comprising children with ASD, their unaffected co-twins, and typically developing comparison children. Methods Participants included families from the Twins Early Development Study (TEDS) where one or both children met diagnostic criteria for ASD. Overall, 181 adolescents with a diagnosis of ASD and 73 unaffected co-twins were included, plus an additional 160 comparison control participants. An extensive cognitive battery was administered to measure IQ, central coherence, executive function, and theory of mind ability. Results Differences between groups (ASD, co-twin, control) are reported on tasks assessing theory of mind, executive function, and central coherence. The ASD group performed atypically in significantly more cognitive tasks than the unaffected co-twin and control groups. Nearly a third of the ASD group presented with multiple cognitive atypicalities. Conclusions Multiple cognitive atypicalities appear to be a characteristic, but not universal feature, of ASD. Further work is needed to investigate whether specific cognitive atypicalities, either alone or together, are related to specific behaviours characteristic of ASD.

Identifying Symbolic Relationships in Autism Spectrum Disorders: A Deficit in the Identification of Temporal Co-occurrence? / Catherine S. AMES in Journal of Autism and Developmental Disorders, 39-12 (December 2009)

This study examined whether these difficulties reflect underlying problems in the identification of temporal co-occurrence, or in memorial, associative, or inference skills. The performance of a group of adolescents with ASD was compared to that of typically developing children and adolescents with learning difficulties on four tasks assessing these processes. The ASD group experienced specific difficulties when they were required to identify relationships signalled by the temporal co-occurrence of stimuli. These results are discussed in relation to theories of conceptual deduction in ASD, and a hypothesised role in social cognitive development for attention processes is outlined.
