The Childhood Asperger Syndrome Test (CAST): Test–retest reliability in a high scoring sample / Carrie ALLISON in Autism, 11-2 (March 2007)
[article]
Titre : The Childhood Asperger Syndrome Test (CAST): Test–retest reliability in a high scoring sample Type de document : Texte imprimé et/ou numérique Auteurs : Carrie ALLISON, Auteur ; Simon BARON-COHEN, Auteur ; Jo WILLIAMS, Auteur ; Fiona J. SCOTT, Auteur ; Carol STOTT, Auteur ; Patrick BOLTON, Auteur ; Carol BRAYNE, Auteur Année de publication : 2007 Article en page(s) : p.173-185 Langues : Anglais (eng) Mots-clés : Asperger-syndrome Autism Childhood-screening Pervasive-developmental-disorder Reliability Index. décimale : PER Périodiques Résumé : The Childhood Asperger Syndrome Test (CAST) is a 37-item parental self-completion questionnaire designed to screen for high-functioning autism spectrum conditions in epidemiological research. The CAST has previously demonstrated good accuracy for use as a screening test, with high sensitivity in studies with primary school aged children in mainstream schools. This study aimed to investigate test–retest reliability of the CAST in a high scoring sample. To this end, 73 parents filled in the second CAST (CAST-2) within approximately 2 months of the first administration of the CAST (CAST-1). Agreement above and below the cut-point of 15 was investigated. The kappa statistic for agreement (<15 versus 15) was 0.41. It was found that 70 percent (95% CI: 58, 80) of children did not move across the cut-point of 15. The correlation between the two test scores was 0.67 (Spearman's rho). The CAST shows moderate test–retest reliability in a high scoring sample, further evidence that it is a relatively robust screening tool for epidemiological research.

WILLIAMS, Auteur ; Simon BARON-COHEN, Auteur ; Carrie ALLISON, Auteur ; Fiona J. SCOTT, Auteur ; Patrick BOLTON, Auteur ; Carol BRAYNE, Auteur ; Fiona E. MATTHEWS, Auteur Année de publication : 2008 Article en page(s) : p.1731-1739 Langues : Anglais (eng) Mots-clés : Communication Social-behaviour Autism Asperger-syndrome Sex-differences Index. décimale : PER Périodiques Résumé : The Childhood Autism Spectrum Test (CAST) (formally known as the Childhood Asperger Screening Test) identifies autism spectrum conditions by measuring social and communication skills. The present study explored the sex distribution of scores. The CAST was distributed to 11,635 children aged 4–9 years in Cambridgeshire primary schools (UK). 3,370 (29%) were returned. The median score was significantly higher in boys (median test, P < 0.001) (Boys, median = 5 (IQR: 3,8); girls, median = 4 (IQR: 2,6)). There was a predominance of boys (n = 81 (79.4%) over girls (n = 21 (20.6%)) amongst those scoring ≥ 15. Exclusion of children with ASC did not significantly affect the results. We conclude that different profiles of social and communication skills in boys and girls must be taken into account when measuring these skills in the general population.

JOHNSON, Auteur Année de publication : 2009 Article en page(s) : p.637-642 Langues : Anglais (eng) Mots-clés : Infancy autism visual-attention gap-overlap-task disengagement Index. décimale : PER Périodiques Résumé : Background: Recent studies of infant siblings of children diagnosed with autism have allowed for a prospective approach to examine the emergence of symptoms and revealed behavioral differences in the broader autism phenotype within the early years. In the current study we focused on a set of functions associated with visual attention, previously reported to be atypical in autism.
Method: We compared performance of a group of 9–10-month-old infant siblings of children with autism to a control group with no family history of autism on the 'gap-overlap task', which measures the cost of disengaging from a central stimulus in order to fixate a peripheral one. Two measures were derived on the basis of infants' saccadic reaction times. The first is the Disengagement effect, which measures the efficiency of disengaging from a central stimulus to orient to a peripheral one. The second was a Facilitation effect, which arises when the infant is cued by a temporal gap preceding the onset of the peripheral stimulus, and would orient faster after its onset.
Results and conclusion: Infant siblings of children with autism showed longer Disengagement latencies as well as less Facilitation relative to the control group. The findings are discussed in relation to how differences in visual attention may relate to characteristics observed in autism and the broader phenotype.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.02051.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=732
